I think that all proper maths questions, asked recently, have received an answer by me or by someone else.
If your maths question didn't get answered bump it up by 'answering' yourself. State that you still need help.
If you need more explaination post again and explain what you want.

Other people who answered questions today (Sydney time) were
Kitty<3
NickB
Jillianj17
Bob
and
Professor Lopez.
If I missed anybody I am very sorry.
Thanks guys, I appreciate all your input! This site can't work without people like you!

I would like to stress that this site is best used if we help people to learn.
If you just give the answer that, most likely, won't help learning.
If you give very full worked answers, that might be good but it might be better to give half answers or to answer a different, similar question so that the person who posted has to do some of their own thinking. It is also okay to throw some ideas or questions back at the person who posted. If they are seriously interested they will get back to you. If you can interact with the person they will learn better.
I am a qualified mathematics teacher, a good one I believe, if you want any guidance, or if you want to comment, or maybe you have some great ideas of your own, you can talk to me in a post or you can send me a private message. You will need to be a member before you can access private messaging.
Thank you
Melody.

Best AnswerThank you Puzzled, I am glad that you are enjoying the forum. That makes me happy. Puzzled, if you have done some graphing of trigonometric functions you may like to dig out a recent post by 'Nobody Special'. You may find it interesting. I think it was yesterday or the day before.

That's it for today.
There are a couple of very recent questions that really haven't been properly answered but the rest are all answered.

some of the helpers today were
aaaa, Bliu1, Bob, 1<3 Algebra, Kitty<3, omkar, At least one guest and DavidQD.
There may be others as well. Please accept my appology if I missed you out.
A big thank you to all of you. The site can not function if people don't answer questions.

We are very fortunate to have DavidQD with us. He is a very clever mathematician. He is busy so he probably won't answer that many questions but if he answers yours you can consider yourself very honoured. Please make him feel very welcome.
Thank you David for joining us.
David, there was a question a couple of posts back by Lomsor that you might like to take a look at. I have played around with it a little but maybe you could offer input.
Thanks.

Good night all. (there are no sleepy smilies - what a pity)

Another day down. It is sunday night (actually monday morning) here in Sydney. 3:40 am and already hot.

Zamarroncis gave me a great answer to a continuing thread that i only just started - on the divisability of numbers.
Jazz gave some fantastic answers.
A guest also gave a good answer - it would be nice if you had a name.
fsad gave an answer, which is good, and I am sure next time he/she will try to make it more helpful.
-----------------------------------------------------------------------------------

I'm going to take this opportunity to point out the sub and sup buttons above the smilies on the posting page.

Sub stands for subtext. If you want to put a little number (or text) just below the normal text line then you highlight it and press the sub button. example; X ₁

Sup stands for supertext. this is for when you want to put something just above the normal text. It is what I use when I am writing powers and it is easier to read than using the ^ button.

so 8^(3b) = 8 ^3b

to get this I wrote 83b then I highlighted the 3b then I pressed the sup button.
It makes it a little harder to read when you are actually making the post but that is what the preview button is for.
The preview function should be used to check that everything looks as you intended.

Melody · Answer 5 · 2014-01-13T11:47:38

Another day and all questions are answered.

There were sum fantastic answers today from Doc, Zamarroncis, Gene, and Sp3ctr3.
Thanks guys - that's fabulous.

Doc, I would like you to go back to the divisability post and reply with some examples of what you meant.
Some people wont understand if you don't illustrate what you mean with an example or two.

Sorry guys, not all questions are answered to this point. I've run out of time.
There are 5 posts that I seriously want to return to, I might not get to all but i will try.

There were lots of great answers given by helpers today. Otherwise there would be even more posts unanswered. Thank you so much.
Helpers today were
Sudenpur, Bagelfood, mathnut 8, unicornrainbow, 2548, MissLuna, Zamarronics, Dee, and a couple by 'guests'
oh, and there was a great little sketch by NoTrees.

Good night all.

Okay, I have finally got through all todays questions.
They all have good answers either from me or from one of you.
There are still 2 left from yesterday that I still intend to get back to
I should be able to do them tomorrow.

Helpers today included
Mighty, Sammy, Q-Who, Zamarronics, Kitty<3, one or more 'guests'
plus an WFT- an ocean of rice (who has been asked a clarification question which is not answered yet)
A really big thank you to all of you.

I was thanked by Echo and by a 'guest'. I appreciate this, i give my thanks in return.

-------------------------------------------------------------
When people post offensive material generally I think it is best to ignore it.
If it doesn't gain attention then the poster will probably decide it is not worth while and will either go away or will improve the quality of their posts.
That's my theory anyway.

Today someone used a post to bully another member. I don't think this sort of behaviour can or should be ignored or tolerated.
I told the person that this was not acceptable behaviour in this forum.
Last time this happened, Professor Lopez told the bully that their behaviour was not going to be tollerated and the bully just gave a little mouth full and left the forum.
I was very grateful to the Professor for her action.
I hope that my words will be equally effective. Of course, no one needs to leave the forum, they just may need to change their behaviour.
I would like you to support me, and let bullies know that that type of behaviour is not acceptable here.
Don't start calling them names or anything just be very sensible about it and show that you support the person being bullied and not the person who is doing the bullying.
If anyone has any good ideas on how to handle this sort of problem i would love you to speak up, or if you would just like to comment, that would be good too.

Thankyou all for making this forum so worth while.
Melody.

Everything is all up to date now.

Helper today included reinout-g i_luv_math_300, cxz\xc, and a couple of guests.
Thank you, your answers are really apreciated.

I would like to remind everyone that the aim here is to help people learn. If you give an answer without an explanation then not much learning is going to happen.
Therefore please try to explain how you got your answer.

Iwilli28 offered a number question. I think it was intended as a sort of number puzzle. '28 tacked it onto another post.
I reposted it awith the green smilie symbol.
Thankyou Iwlli28 for your contribution.

I know people are getting very busy with school and other activities but could you please make a contribution to the puzzles and continuing posts from time to time, just to keep them rolling.

Thank you everyone

Another day over,
A big thankyou to AA22 and Lexi24 for your helpful answers today.
---------------------------------------------------------------------------------------------------------------------------
I might take this opportunity to suggest that when you make a post you
a) give it an appropriate title
b) Say something about what you have attempted yourself and why you are having problems.
(eg I don't understand the neg signs or I'm not allowed to use a calculator)
c) Give some indication of your age or level of study.
An answer that is good for a standard 14yr old may not be best for a year 12 or a year 6 student.

Thank you and good night.

Melody · Answer 12 · 2014-01-20T01:59:04

Another day done.
There were a couple of top answers posted by teach and Walt plus some others by one or more guests.
A big thank you to each of you

There were 2 questions that i have not done yet.
I think they were called "Measurement" and "Teacher trying to flunk me"
these were both difficult questions and I didn't have much time today. Maybe I will suceed tomorrow, or maybe one of you will beat me to it.
Most of you would have the skills needed, they are just difficult puzzle type questions.

I wrote an information post today on how to deal with negative indices. If these give you any grief you should take a look.
I put an i symbol next to it to help it stand out. I have decided to use that symbol for information posts.
That's all folks,
Good night.

Melody · Answer 13 · 2014-01-21T10:01:07

There were some excellent answers today from Sportsguy007, Walt, Zamarronics, Nobody Special, and guest. I really appreciate your efforts and I am sure that the people who posted the questions all did too. There really are too many questions for me to answer them all, plus the fact that I don't want to.
Walt answered one of the difficult questions from yesterday so there is just the one unanswered one left (Walt posted it)
Zamarronics, I thought you might like to take a look at Walt's questions. I'll bump them up so they are easy to find.

Please note that indice (exponent) questions and answers are much easier to read if you use the superscript button 'sup', that is located above the smilies, instead of using the ^ key.
Try and keep that in mind.

Thanks everybody.

Another day gone and we will never get it back again. or

There were some great answers and participation today from joelhdzfdz, Nobody Special, Lauren1213, Homelesswolf, Kitty<3 and guest.
Thanks guys, I really appreciate it.
NOTE: When I talk about a guy (singular) I mean a male, but when I talk about guys (plural) it includes both males and females.
It's not just me, everyone in Sydney uses the words like this. I guess I can't really speak for the rest of Australia. Is it different overseas?

I bumped up some old posts that I want more people to see, or perhaps, to keep seeing.
Walt's questions (2 in one post) still haven't been answered but I think all the others have.
I answered one a bit - not a proper answer - really just some thoughts.
I still challenge Zamarronics to answer them, or anyone else, that would be great

Pleasant Dreams,
Melody.

Melody · Answer 15 · 2014-01-23T12:51:04

Wow, that was the most posts that we have ever had in a day. Just as well I have so many people helping me now days or I would never cope.
I would hate to think that some people's perfectly good maths question would go unanswered. That would be very sad.

Helpers today included SnowRobin, tanker_girl7777. Kitty<3, Yugarian, Walt, Justsmile, lol at this, hhh....., MathNerd741 and a few guests.
There were also a couple of thankyou's from people, that is always nice (one of them was for Kitty)
These days most people give excellent answers. I would like to remind people that generally speaking 'answer only' answers are usually not much help. Plus, if you use a formula in an answer it is a good idea to write the formula out first, rather than just going straight to the substitution step.

My friend Romsec has done one of Walt's difficult questions. I haven't given the entire answer to Walt. I am going to make him do some of it on his own
A few of my friends have banded together to do walt's other difficult question. I am not sure but the final answer might be in.
Walt i am still waiting on you to simplify your divisabilty by 4 test. I am sure one of you others could do it. How can you tell easily if a big number is exactly divisable by 4?
This is in a thread called " how can you tell what a number is divisable by". (It is denoted by a green smiley in the margin) I'd love to see a simple answer posted on this one.

I think that's it for the day. Some of the helpers I haven't noticed on the forum before. If you are new, welcome, I hope you like it here and that you stay and answer more questions.
Thanks guys and good night.

Lot's more questions today.
I never could have answered them all on my own, I am so lucky to have so many people helping me.
Today there were some really great answers given by Walt, Serjio, Kingcong, Kitty<3, Lucas, zoomasd, and I like Serena.
Thankyou all for your efforts. The quality or your answers is really great.
I like Serena only joined today, welcome to web2 forum, we hope you like it here.

Walt gave a great answer on the 'What is a number divisible by' thread. Now I am waiting for another contribution! (maybe from someone else)

Zoomasd answered the "number puzzle" thread. He had problems with it but that is okay. I have given him some help and i hope he has another try tomorrow. I really appreciate your input Zoomasd.

Kitty had a couple of great thank you's from people she helped. That is always nice. Ayee got upset with me. That's okay, I deserved it and i am sorry I upset her.

Oh, one more thing. Acronyms are commonly used in maths. for example. LCM of HCF but if you use these in your answers could you please write the whole version as well. People do need to learn the acronyms, but they can be very confusing if the person doesn't know what they mean.

Thanks everyone. See you all tomorrow.

Melody · Answer 17 · 2014-01-25T08:26:46

Another day done,
some good answers were presented by I like Serena, kitty<3, Lucas, bechapm, DavidQD, and Anonymous4338.
Anonymous4338 pick up on it when I didn't interprete a question the way we both think it was meant. That was really great.
DavidQD gave a fantastic final answer to Walt's "My teacher wants to fail me" question. So now, Walt you should be able to 'knock your teacher's socks off'

Aadilk96 did the most recent number puzzle. That was really good to see.
I have posted two more puzzes on that same thread. They are similar but one is difficult and the other is much easier.
Take a look and answer, or ask for a hint, on the one that best suits your ability level. Playing with numbers really will help you to understand them better

'I like serena' answered the next bit on the 'what is a number divisable by post. He? was being a bit cheeky really, 'I like Serena' is a very good mathematician and I am hoping he/she will stay and answer lots of questions, especially the physics question. We would all really appreciate it if you stay and help us out. (Now I need a clapping emoticon, we don't have one, what a shame)

The last thing on my mind is that I would really like some people to think about what an appropriate title for their post might be.
It can make quite a big difference to how quickly your question is answered. It also makes a big difference to how easily it can be refound if it is not answered straight away.
There may have been an extreme case today. I like Serena was answering questions, with what appeared to be a preference for physics questions. Princess Sophie had posted a great physics question but the title was 'math'. I think 'i like serena' simply didn't see it and it is the only question that has not been answered today. If it had been called Physics or Forces, it probably would have been answered already.
That's it, for me it is Saturday evening, for most of you it is Friday night. So, have a great weekend.

Melody · Answer 18 · 2014-01-26T11:20:42

Well, my Saturday is finished. It is even later in New Zealand, that is, just after midnight, Sunday morning.
But, almost everywhere else in the world is behind Sydney (in time, that is).

We had some great answers today from Anonymous4338, Anonymous#16, Princess Sophie and Kitty<3
I like Serena and DavidQD also gave Princess Sophie great answers on her difficult question from yesterday.
Thankyou everybody. You all did a great job
----------------------------------------------------------------------------------------------
Please when you write your questions could you be very careful to use brackets to make your meaning clear.
Too many brackes is usually less confusing than too few. Just try to keep that in mind.
good night.

Monday (for me) is over. It's been a great day. (It is Australia Day long weekend so we had a traditional Aussie BBQ)
Once again lots of fantastic answers came in. Contributors were puzzled, I like Serena, Hello, Kitty<3, imfifteen, reinout-g and a guest.
reinout-g has shown him/herself to be a very capable mathematician.
However reinout-g is having a problem with a matrix question that I cannot help with.
If anyone has good knowledge of matrices could they please try to help reinout-g with this question.
I think the title is 'Stuck on proof'.
There was another incidence of bullying today. I think i have handled it. This sort of behavior should never appear to be condoned. That is very important.
I am very pleased with how the forum is progressing.
Thankyou everybody.

Melody · Answer 20 · 2014-01-28T01:03:00

hi everybody,
Some great answers were posted today by reinout-g, I like Serena, mathsabi, superman Seth Rocks, Kingcong,Walt, Kitty<3, Puzzled, guest and The dumb guy, (i think that i will just refer to you as The Guy in future, unless you don't want me too ) The quality of your answers is consistantly high. I am thrilled.
Thanks guys

I started this Forum rolling almost exactly 4 months ago, until that time, very few people posted questions and most of those were not answered. The forum has grown enormously since then. Up until today i have always checked every single answer. This is no longer necessary, your answers are great, and soon it won't even be possible. So I will no longer be doing this with such diligence.

Also I am very pleased that we now have at least 3 people who are capable of answering questions that are beyond my capabilities.
These members are DavidQD, I like Serena and Reinout-g. I am really pleased that you have joined us. Actually I am very aware that many of you others are extremely bright young people, so in a couple of years or less, many of you will also surpass me in ability. I will be very proud of you and pleased that i have contributed in some small way to your education!

Reinout-g, I examined your complex number solution and am pleased that I did make sense of it. Thankyou very much for that. I really appreciated it.

Now we have Jedithious back. With Jedithious and Puzzled and Walt and reinout-g and The Guy (and maybe I like Serena and myself) all here, the Puzzle posts should be given a kick along.
I think perhaps all these members solved puzzles in the last couple of days. Jedithious posted some of them! I will give the puzzle posts some attention tomorrow. I didn't have time today, sorry.
If you solve a puzzle it would be good if you could give other members some idea to your thought processes that you had. If this is too difficult or you don't know what i mean, i will try to do it for you. If you watch me you will get a better idea of what i mean. People can learn a real lot about numbers if they learn how puzzles are done.
Puzzled did this beautifully today with a puzzle that Jedithious had posted.

Anybody would think I was writing an essay!
I'll go now, good night.

Hi everybody,
Actually I don't think it was so busy today. Maybe that is just because I was a little less hands on. There was more time for puzzles which is great.
Once again there were some fantastic answers by reinout-g, anonymous4338, I like Serena, The Guy, Zamarronics, guest and unknown name.

Once again i will stress that answers without good explanations are not of much value. Please do not give answer only.

It is always hard to know what to do when people make a nuisance of themselves.
Generally speaking it is probably best to ignore them.
If you think differently, that is fine.
Goodnight all and thankyou for making this forum such a success.

I believe that is it for the night. I have not checked every question, if you are not happy with your reply bump your question up with a comment about why you are doing so.

Great answers were given by guest, reinout-g, halper, I like Serena, Anonymous4338, Zamaronics, DavidQD, Rom and Kitty<3.
Rom only became a member today. We hope you enjoy your experience with us.

Reinout-g posted 2 really good puzzles. One he called Logic's puzzle. It had me stumped but a great answer came from theiswe.
reinout-g has also posted a new number puzzle. I normally do these very easily but this one appears to me to be very difficult.

I know that some people, even some core people are not formally members.
There are some big benefits to joining up.
1) It is a little easier to make a post.
2) Once you have made a post you can edit it if you are a member. I edit my post all the time. I would hate not to be able to do that.
3) You can also delete your post so long as no-one has answered you yet.
4) No-one else can use your username
5) You can send private messages to other people and make real friends. I know that I have

Thanks reinout-g for your calcuator tips. I haven't really looked at them yet but I will.

SUP button
I really want people to learn to use the 'sup' button instead of the ^ . It makes it so much easier to read.

Hi all,
Another day done
Great answers were given by Rom, I like Serena, The Guy, Expertise, Selina Marie, Right and Archhunt.
Archhunt only just joined up today. Welcome to Web2.0calc forum. We hope you like it here.

Reinout-g i have left messages at the end of your calc display posts, specially for you, oh, also on your puzzle post.

The forum is evolving very quickly now. Some of it is very exciting, other things I am a little concern about.
I don't know if it can, and I don't know whether other peoople will want it to, but I would really like this to stay fundamentally a children's forum.
There are many forums around for older people but I haven't seen many for younger people. Most of you know that it was only a week or so ago that the children and I were the only ones in this forum. ( I use the term loosely, I know that many are not children, maybe young people would be more accurate and less offensive).
I always encouraged the young people to answer, even if they got the answer wrong! I think people are much more likely to learn if they are also actively participating. Plus, teaching is a learned skill and this was giving the children a chance to learn. They responded extremely well to my guidance when it was given.

Maybe I am wrong but I expect some of the young people are already feeling 'crowded out'. (I really do not think that I am wrong). Some of the young people were giving extremely good answers on a very regular basis. I know that most of the questions will always be answered by adults and I am very genuinely grateful to all of you who have joined us. I was starting to 'burn out' and I was well aware that I needed more help. I also know that when questions are asked, the person asking is wanting a quick and accurate answer.
However, I guess I am asking you to give the children a little time to answer some of the questions themselves.
I would like the adult mathematicians to check that the answers given are correct, I see this as a very important role. Please don't think that I am aiming this at you or at any individual. We are all guity at times. I am just trying to give you an insight into what I am thinking.
Kind regards to all.
Melody.

We had some great answers today from Rom, I like Serena and Selina Marie. Thanks guys.
Thanks for giving the young people a chance to answer today. It is a pity that only Selina took advantage, but it is Friday. Not many people want to do homework (even other people's on a Friday).
Thanks Selina Marie for that great answer. You gave a great one yesterday too. Why don't you join up properly and become a part of the team? That would be really good.

Hi all,
It was a quiet weekend day today.
There were a couple of good answers from Rom and Keltoi. Thanks guys, your answers are much appreciated.
I like Serena gave the forum a great parametric equation to use in Desmos Graphing calculator. You will have to actually use it if you want to know what it is
I put out a post reminding the question presenters that good manners are always appreciated. i will bump this up in front of this post. I don't know how much difference it will make but it can't hurt to remind people every now and then.
There is one unanswered question, it is called "Pearson's r and coefficient of determination" by Shoni. I will bump it up so that it is easy to find. If no one can help her she will need to be referred to a different forum.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Now, our new adult mathematicans are I like Serena, Reinout-g and Rom. I would like to introduce you all to Kitty<3.
In the weeks prior to you joining this forum Kitty was my right hand girl, I really don't think I could have coped without her.
She is a sophomore student, which to the best of my understanding is just pre-calculus. Kitty answered many of the junior High questions.
Her answers are always of an extremely high quality.

She wasn't on the forum much last week so i wrote and asked her how she was feeling about the changes that have taken place.
This was her reply.

"I would agree that this forum would work better for mostly younger people who have simpler math questions, as there are quite a lot of physics and higher-level math forums out there. But it's nice that more adults are helping out here now. Personally, I didn't really feel left out, just busy and bombarded with essays and homework.
It would hopefully work out beautifully if the kids could answer and the adults could help check the answers. That, as you said, is an important role, and both the kids and the new adults could help out "

I just wanted to introduce Kitty<3 because i think that it is important that all the key answer providers recognise each other.
Good night all.

Hi everybody,

We had some great answers today from DakenSoren, Flarp, Abhi, lilipop, Singfur, Rom, DavidQD, and several by guests. I think there were a few questions answered by the same guest. Why don't you sign up or at least choose a name. That would be really good because I love that you attempted so many questions today and I would like to know who you are .

I actually had a problem with a question today. I answered it but I would like input as to how it should be interpreted. (I am not sure if it is correct) This is the page.
http://web2.0calc.com/questions/help_179

There were three of the more difficult questions that I didn't get done. Time was a problem today.
I will bump them up after I finish this post.

Good night all.

Hi all,
I am in a good mood because i just did the puzzle question (math by gutierrez) totally by myself.
Reinout-g said it was likely to cause him sleep deprivation, and I like Serena resorted to Wolfram|alpha.

Alright, enough about me.
There were many great answers given today by Rom, I like Serina, Not a homosapien, Blogganta, Selina Marie, Justin,Amos Tomlin, MissRaevalynn.
A big thank you to all of you.
I also saw a nice thank you post from Zamarronics (for DavidQD). Thank you on David's behalf.

It appeared to be unanimous that -x ⁿ should always be interpreted as -(x ⁿ). I was troubled about this yesterday.

The number of questions that are being posted appears to be growing exponentially. I did expect this to happen but that doesn't make it any easier.
I am thinking that perhaps we could more often refer students to a learning resource like a you tube clip or a mathsisfun site. I don't want us just to do a student's homework. I think I caught someone today posting a series of log questions. Maybe, with the more advanced students, we could start requesting more interactivity. With the younger ones we could do a similar problem rather than the one they present us with. I want the site to be very friendly but some of these tactics might discourage some of the people who are using us in a not so desirable way. I personally am answering far more questions than I really want to. Rom answered a great many today as well. It leaves little time for other things.
I am probably giving mixed messages (to people who answer questions). I am sorry, I am trying to feel my way.

There is a new post running asking for people to add ideas and comments relating to all aspects of the forum. Please use it. I really do want your input
On a very positive note there appears to be a greater number of students posting answers. This is exactly what we want. Thanks folks.
Melody.

Hi everyone,
Today we had some great answers from Rom and J-Rad, thank you, your efforts are much appreciated.

It was a very quiet day. This morning the forum was full of snark posts. I am sorry Rom, that you were so bombarded. I have not seen so many for a very long time.
I think that these posts should be totally ignored. I have found that silence is a very good deterrent. The young people who have been here for some time know that this is what I think and they are usually supportive of my position.
Also, I have no problem with a little bit of play happening in here and if anyone wants to join in on some harmless fun I most certainly have no objection. I would like the forum to be a little light hearted sometimes.
My only exception to 'the silent treatment' is if you discover any bullying, even if it is only very mild. If you see any bullying could you let me know asap please. You can either send me a private message (I check them fairly regularly) or you can leave me an attn: post, with the attn post symbol that I have been using in the margin. If I am not around I guess you will have to play it by ear. Don't make threats that you can't back up, don't stoop to bullying the bully. Just tell the person very firmly that their behaviour is not acceptable in this forum. If they want to stay they have to 'be nice'. In the past I have always found that this is enough. If the bullying is very mild it can be dealt with more gently.

Please check for messages regularly. You just have to left click on your username. There are no automatic reminders here.

I sent 'Admin' a note last night thanking them for providing this forum for us and asking if they could do some upgrades. I asked if it would be possible to get more pages so that we could separate different types of posts and I ask if they could install LaTex into the forum. The message is still sitting in my outbox which means that they have not opened it yet. Web2.0calc has never responded to any of my messages so I won't hold my breath, but I will keep you updated if there are any developments.
Thank you,
Melody.
Edit: I nearly forgot, there is a question that i answered but I am not sure of, maybe someone would like to take a look.

Good evening everyone,
It was really hectic today. The questions never stopped.
There were some great answers provided today by Bob, Rom, I like Serena, Princess Sophie and Guest. Thank you all.
Warped Tour Girl (who has been with us since our quieter days) Gave Rom and me a very nice thank you for our efforts.

Reinout-g gave some feedback regarding organizing our resources. At the moment I am starting to 'throw them' into onto one of the information threads below. They will need to be organised better than this eventually. Some things will need there own posts but I thought we could eventually, when it is organised properly, take a page each to use for our own selections. Obviously the individual will need to be responsible for his/her own page, since no-one else will have editing access. There is a free program called Gyazo which acts like the snipping tool accept the picture gets stored in the cloud and it has its own address that can be shared. Maybe we could make good use of this. My computing knowledge is quite poor. Maybe other people have better ideas.

That's it.
Goodnight all.
Melody.
Edit: Doesn't anyone know how people are including symbols such as integral signs and +- signs into the body of their posts?
I thought perhaps they are using the control key. Any thoughts?

You can do that by copying and pasting from about any source.
When using Windows you can use the Accessory Character Map to copy and paste them.
Pick any site where you can type latex, and you can copy and paste the symbols when viewing the result.
Pick any web page where the symbols you want are listed, e.g. wikipedia, and you can copy and paste them.

Melody · Answer 31 · 2014-02-07T09:32:23

Hello everyone,
Today was a little quiet, for me at least, which was really good.
There were some great answers from Rom, Reinout-g, myrandomusername, unknown name and guest.
Lostjr126 answered 3 puzzles, he/she is only in 6th class, and he/she only joined today. Maybe he/she will be a force to be reckoned with in the years ahead.
There were also some really nice thank you's from Lostjr126, tannawirsch, and PaPreciousVang. It is always nice when people express their appreciation.

There is one unanswered question http://web2.0calc.com/questions/malaria
I didn't think it made sense but I could be wrong.

In regards to yesterday's request. Thanks I like Serena, I just found the character map, I haven't tried to use it yet but I certainly will.
Reinout-g also added some web addresses to our, as yet unsorted, thread of resources. Thanks Reinout.

I really like Rom's answer when someone ask him 'What is pie" He just gave a web address. If you want to know what is is you will have to take a look.
http://theotherdayatportrait.files.wordpress.com/2012/03/pi7.jpg
Thanks Rom, You always give good high level answers but I liked your younger, and also your more light-hearted answers that you gave today.

Stu, joined us yesterday and is making good use of the forum. He posted under one of my information posts. When i pointed this out, he said, "well isn't that what it is there for" .
Maybe he is right, maybe we should start some threads with really appropriate titles, The first post/s could be a fairly comprehensive look at the topic. Then the people asking questions could either continue the thread or if they post elsewhere, they could be directed to the thread. I have never made good use of the Search Box at the top of the questions. But if the thread is titled appropriately, it does seem to work very well. If the search works well there would be no need for me to bump the threads up each night. Any comments on this idea?

That's it, thanks everyone and have a great weekend. (Mine has already started)
Melody.

Hi everyone,
I was hardly on at all today. I did check quite a few questions and I answered a couple but compared to usual I was hands off.
I am really pleased with how things are developing and how much everyone is helping.

There were Lots of great answers today from Rom, MathHelp, Stu, Gibsonj338, and guests.
Lili and a guest were joking over a snark question. It was all in good fun

That's it I think.
Good night,

Melody · Answer 33 · 2014-02-09T10:11:53

Good evening everyone,
Another very quiet day today.
However, great answers were forthcoming from Rom, DavidQD, gibsonj338 and guest. Thank you.
I used the character map that 'I like Serena' told me about today. It was really good. Thanks ILS

A lot of people, including myself, originally think that the message system doesn't work.
This is because messages seem to 'get stuck' in the outbox.
The system does work, the messages will stay in your outbox until the recipient opens it. The message will then move to 'sent messages'.
While the message is in the outbox, you can edit it and you can delete it.
If you delete a message that was already in the outbox then the recipient will still receive a message. The message will tell them that you had sent mail but that you had already deleted it.

If you choose to, you can be notified of new private messages.
To do this go to the User Control Panel and choose the Board Preferences tab. Then select "notify me of new private message".

Enjoy the rest of your weekend,
Melody.

Hi everyone,

Great answers today from Rom, lol no username, hampy canper and Kitty<3.

Herpaderp, guest and free answers XD: I really liked that you got involved today and gave full answers. However, I would like you to look at what I wrote after your posts. This way you can learn too.

Stu and gibsonj338, thanks for answering the snark 2+2 question. I am interested to see if this tactic has a positive impact. It may do, I don't know. The usual policy is to ignore such questions.

Stu wrote an information post on how to search the forum. He called it "How to Search: find what you want!"
Thanks Stu I hope that this information is well used

Edition:
I have added 2 information pages.
One is entitled "Information pages worth keeping or developing"
the other one is just "Puzzles"
These contain the web2 addresses of all the relevant posts. I am not sure yet but I thought that instead of bumping lots of posts up I could just bump these 2 up.
Does that sound like a possibility?

That is it, I think.
Thanks everyone.

hi everyone.
The new week has seriously begun. - all over the world that is.
I am really lucky to have so many wonderful people supporting me and supporting the forum.
Excellent answers today from agooch99, Daniel999820, Stu, non, Hipster02, I like Serena and autumn.
And of course Rom. What would we do without you?
A very big thank you to all of you.
Stu has added a Top free sites post. He has added mathportal.org It looks quite good. Thanks Stu.
Stu has invited other people to add to this thread.

Please everyone. If you do not like snark posts such as 2+2 do not respond to them.
If you want to 'play' with such a post that is fine. BUT if annoys you, please DO NOT respond.
Silence is the very best deterrent. I am quite convinced of that.
There has not been any bullying here for quite some time, but I remind you, if you see any hint of it I want to know asap.
You can send me a private message or you can make a post stating the problem. You could label it "Attn:Melody" with an attention marker in the margin.
That should get my attention.

Once again I ask people to give a little thought to the titles of their posts. 'Math' or 'question 9' really reveals nothing about the problem at hand. I think i might start purposely answering properly labeled questions first. Make the others wait longer. I am probably preaching to the converted in here. Sorry. I'll make a separate post in the body of the forum.
That's all,
good night,
Melody.

Melody · Answer 36 · 2014-02-12T10:26:12

Hi everybody,
Another busy day. I think that Rom and 'Someone' answered the most questions. Thank you for all your efforts.
Hi, someone, It is nice to meet you. I don't think that we have met you before, It would be really nice if you joined up properly. There are a number of advantages but I don't think that I will go into them all now.
There were many other great answers from jyotig, Letchersavanna, dealor and a number of 'guests' A big thank you is given to all of you.

* I also received a nice thank you from a guest. It is always nice when people show appreciation.
* Happyfeet has started her? own snark thread named "Why so hard" A couple of people have joined in the fun, including myself. If you don't like insincere threads I suggest you stay clear of this one.
* There was a new 1+1 post and I am please that everyone ignored it. That particular snark is getting a bit tiresome.
* There was one crude post. I was tossing up whether to say anything. I think that if it had been very near the top I may have, but it had already moved down the list and if it had been responded to, that would have put it back at the top again. If it is left alone it moves off the first page quicker. Did I do the right thing or should I have said something. Any thoughts?

* I used the display feature of the web site calculator today for the very first time. It was very appropriate to the question. Thanks Reinout-g, if you had not brought it to our attention it would have continued to be an ignored resource (by me anyway).

I would like to suggest that people look at their own answer posts at the end of the day. Sometimes they have been added to by others. There may have been a problem or someone may be trying to communicate with you.
Also, I think that looking at other people's posts is always a good idea. You may learn content or you may get alternate ideas on how to present that content. I have learned a lot by watching others.
That's it,
Goodnight all,
Melody.

Good evening everyone,
Great answers today from Grammar Fascist, Kobeguapo, I love Serena, Rom and CMW. Thank you one and all.
Grammar Fascist made many high quality answer posts today, they also became a member.
Thank you for joining us. I can already see that your contributions will be highly valued here.
Thanks were also received from a guest, from Blank and from Stu. Thank you, it is always nice when people show their appreciation.

I wrote or tweaked two new info posts.
I called one "Become a member : Why would I want to?"
and the other "Good Manners are always important"

There was a snark post today by Bill Billerson which provided many of us with entertainment.
I often enjoy a good fun snark that is fresh to the forum.
The last entry was from Stu. it was a you tube clip and, i will admit, I really enjoyed it.
Plus, I actually didn't know what a woodchuck was so now I am further educated
Anyway, if you want to take a look at what I am talking about, here it is http://web2.0calc.com/questions/help_186
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
There have been a lot of questions lately on factorising the quadratic equation. (Someone really should tell this spell checker that I am Australian and factorisation is spelled with an s !)
Anyway I digress,
I would like people to look at these two you tube clips, I think that they should be incorporated into you answers quite often.
The first one is how to factorise any quadratic equation: http://www.youtube.com/watch?v=ZQ-NRsWhOGI
The next one is on how to remember the quadratic formula. I know that this really does work. Plus it means that you don't have to write out the quadratic formula yourself.
http://www.youtube.com/watch?v=O8ezDEk3qCg
The last is a post that I did that accompanied the first video - this probably would not be used as often as either of the two clip although it does include the first clip at the end.
It is probably worth taking a look at. http://web2.0calc.com/questions/viewtopic.php?f=2&t=8641&p=18347#p18347

I believe that all these web addresses, or the pages that contain them, are include in the summary list " Information pages worth keeping or developing" that I have been bumping up every night.
Goodnight everyone.
Pleasant dreams.

Good evening all,

There were great answers today from Rom, Zethwolf, Dude and I like Serena. A big thank you to each of you.
There were also thank you given from Princess Sophie, Jiotig and Zethwolf. It is always nice when we receive thanks for our efforts.

There was an incidence of rudeness directed at an answer provider. I dealt with it and was given an initial apology. I have asked for a little more than that so we will see.
Anyway, a genuine apology was given so I don't need to make too big a deal out of it. This is the first time, in the 4 and a half months that I have been here that anything like this has happened.

I discovered today that we can tell if the person making a post is a member or not.
If they are a member, their username is blue, if not a member then the username is black.
I think if we ever have days where we can't get to all the questions, the members should be given priority.
I added this to the 'Become a member : Why would I want to" post.

I have been using the character map since ILS told me about it. I really like it but I can't find the symbol 'pi' which seems really strange. Maybe it goes by a different name. Any suggestions?

That's it for tonight,
Thank you everyone,
My weekend has started, enjoy yours when it arrives.

Well now, that was two weird days,
I hope we never get another one like those !

I think that Andre Massow (creator of web2.0calc.com) heard all our cries. He sent me a very nice email.

Basically he said he is working very long hours and is self funding the site and it has been difficult for him.
He apologized for all today's technical difficulties but said that the servers are working to capacity and the site will have to be revamped in the not too distant future.
Andre said that a lot of processing capacity was used to keep spam posters out of the system. For this we should be very grateful. I have seen forums overrun by spam and I always wondered why this forum did not get similarly swamped. He was concerned though that someone was using an adblocker on the site. He needs genuine adds to generate funding. I know nothing about this, if anyone else does perhaps they could send me a private message.
He thanked me for all the time and effort that I have given to the forum. It is always nice to be appreciated. He said he had not answered any of my correspondence in the past because he gets swamped with emails, he has very little time and he simply had not seen mine.
Anyway, it was not his intent to stop this forum from functioning. I don't think that he realized that it was even being used effectively. He understands now and he says he will be considerate of our needs.

It was obviously a very quiet weekend, (except for the horror cries) but there were some great answers provided by Rom and Demogorgan.
Stu posted two more useful web sites. Thanks Stu.
1) Enrich Learning - this is an enriching maths site rather than a standard learning site, if that makes sense. It looks quite interesting.
2) Tiger maths - Algebra explained and illustrated. This also looks like a very comprehensive and worth while site.
Goodnight all,
I am glad that I am a lot happier now than I was this morning.

Hi everyone,
It was a relatively quiet day today I think. Perhaps people need time to recover from the anarchy of the weekend.
There were good answers provided by Stu, Rom, Vaug13, Jyotig, derp and MathGuru. Thank you.

Tjhill19 joined up to day. We welcome you, and we hope that you enjoy your time with us on web2.calc forum.

Most users are not formal members. Soon, when the restructure happens, they will lose their identity.
It is my understanding that all non-members will simply be labelled 'anonymous'
Some quite active people have not formalized their membership. I think that this is a shame as they are missing out on many of the features that the forum has to offer.
Refer to this page to see what benefits you could be getting.
http://web2.0calc.com/questions/become-a-member-why-would-you-want-to

Some days are very busy and this may get much worse after the site is upgraded. I suggest that the members are looked after first. You can tell a member from a non-member because member names are blue and non-member names are black.
If there is time then other questions may be answered at the discretion of the respondent. I don't want anyone to feel obliged to answer questions. If you want to, that's great. If you don't want to, then don't. It is simple.

That is it I think.
Enjoy the rest of your day.

Good evening everyone,
Another busy day. Great answers were written by Rom, dewicious007, Kitty<3 and guest. Thank you, your efforts are much appreciated.
Two nice thank yous were forthcoming from SelinaMarie, and JyotiG. We really like it when people show their appreciations
We had 3 new recruits today. Banana Bob, mathcalc and dewicious. (I suspect that mathcalc and JyotiG are the same person) Welcome to web2.0calc forum. We hope you like it here.

Today I emailed the letter to Andre Massow, Creator of Web2.0calc.com. Thank you for the concerns that were posted on the thread that I set up last night they were taken into consideration.
In the past Andre has been impossible to contact but he sent me a letter earlier in the week so I am hopeful that he will read my return email and give consideration to some of our requests.
I requested that when the site is upgraded that some changes could be put in place. Probably the most important request was that there be no posting except by registered members. People who answer questions feel that a lot of the answers are not even looked out. It is just too easy to make a post. If this forum is going to last we need to nurture a more interactive and appreciative atmosphere. Most people will not donate their time for free if they do not even receive a thank you.
The letter that I sent was quite long. I discussed the best layout of the forum, the introduction of LaTex, and many other things. I also told Andre of reinout-g's desire to set up a Dutch forum.
Many of you may not be aware of this but this site hosts forums in a number of languages. Unfortunately for reinout-g, Dutch was not one of these.
If anyone would like more details regarding my email you can make a question post or you can send me a private message.
I will let you know if I receive a reply from Andre.

Reinout-g - I would like to take this opportunity to thank you for the work you did towards using the web2.0 calculator. I have been using it quite often of late and I know that Rom has too. I actually discovered only today that i can use it to write the quadratic formula, but I don't know how easy it is to bring that output into the forum. There are still many buttons above the smilies that I do not know how to use. Now that Andre has made contact I would really like to do right by him and use the features that he has provided to their very best advantage.

That is it for tonight,
Thank you everyone,
Melody.

All questions answered except for Stu's general question http://web2.0calc.com/questions/getting-e-e-prepared
and this co-ordinate geometry question.
http://web2.0calc.com/questions/coordinate-geometry . If someone want to look at either of those it would be appreciated.

Great answers were provided today by Rom, Kitty<3, mathcalc, lol, demogorgon and Ferra. Thank you, your efforts are always appreciated.
There were also a nice thank you's given by Helpme, Kitty, hsrc, Melody and Rom. It is always nice to receive thanks.

If you want to bump up your own posts the best way to do it is to copy the last message. Then delete the last post, you will be asked if you want to return to the thread (or is you do nothing you will automatically be returned to the thread) then you can hit reply and post the last content back in again. That way the thread won't just keep getting longer with nothing added. Please only bump threads if you believe you have good reason for doing so.

There has been some bullying the last couple of days, it is always sad when this happens. It tarnishes the forum for everyone.

Great answers were given by reinout-g, Alan, hsrc, Shalhio Stenshi, guest, hoppy, kids, Kitty<3, Isssss me, and Rom. Thank you, you are all invaluable to this forum.

Alan joined the web2.0calc forum last night. We welcome you and we hope that you enjoy the time that you spend here.

Reinout-g solved a puzzle and presented a detailed summary of how he came by the answer. I know a number of people have some interest in these puzzles but they just find them too hard. If they look at the solution methods that have been presented they will learn quite quickly how the problems can be effectively tackled. Also, if the puzzle has already been up for a while, a few hours at least, then you can ask for a hint if you want to.

Hello everyone,

Not all questions were answered today. I simply do not have time to answer every question when I am almost entirely on my own.
I made sure all member and regular helper questions were well answered. I think that I answered most of the others as well.
I left a few easier questions for other people to answer. I was pleased when I later saw that this had happened, for at least some of the questions.
The problem was that many of today's helpers seemed to be giving only the answer. The whole point of answering questions on any academic forum is to help people to learn.
In order to teach, you need to explain how you come by your answers. As I answer less questions, due to growing demand and time constraints, it is necessary for some of you to fill the void. If anyone would like to go back over today's questions and find any that need answering that would be appreciated. I know I can rely on you to help, both today and into the future.
Edit: Reinout has just been in and he says that they have all been answered now. Thank you so much Reinout-g.

Some people are already being a great help. Today, answers were given by Alan, king, fractionman, Red ranger, mathfreak and Queenblogger. I appologize if anyone was left out. Thank you everyone for your help.
I also had a really nice thank you from ihatetrig. We all like to be thanked for our efforts, I am no exception, I appreciate your show of gratitude.
A really interesting question was posted yesterday. Alan answered it and I added a little afterwards. Some of you may like to take a look. This is the web address.
http://web2.0calc.com/questions/coordinate-geometry. Highlight the address, right click and choose goto.
I will bump it up so that it stays visible for longer.

That is it for the evening,
Melody.

Good evening all,
Well, it is evening if you are in Australia or New Zealand. The rest of you have to put up with 'Australia' time.
I was a busy girl today. Lots of great questions. I did get some much appreciated help from idkman, I like Serena, apt5004, kitty<3 and Alan. Thank you.
I also got 1 nice thankyou from a guest.
All questions are answered except 1 and a bit.
I will bump both of them when I finish this post.
Thank you all and good night.
Melody.

Good evening everyone,
There were lots of great questions today. Good thing so many of you were helping me answer them.
These answers were provided by Crass, ezom , Alan, Rom, guest, Thatmathguy, anonymous_4481, and unknown,
Unknown provided a few top quality answers, it would be really great if you joined us officially and took a title more worthy of your contributions.

A guest by the name of 23232323.. posted on the end of an unpleasant thread. 2323 politely explained that this was a children's site and the language and content was not appropriate. There were no more unpleasant posts after this. Thank you 2323..
My normal policy for this type of behaviour is to ignore the post. People are looking for a reaction and if they are ignored they soon get bored and go away. However, i am sure that some people just arn't thinking and an explaination such as 2323.. gave is all that is needed to improve the behaviour. This time it appeared to have been successful. So, once again,thank you. 232323.. Why don't you join us properly 2323. There are some good advantages. See the post titled " Become a member - Why would you want to." We would all like you to join

I did a probability post today and I am always a tad unsure of my ability with these. I believe the method is correct though there could easily be a careless error or 2.
Would someone with lots of probability confidence take a look please. If you do check it just add a checked post on the end of the thread. That would be really good and then I can delete this paragraph. Thank you.

That is it for the day.
Thanks everyone

Hello everyone,
It was a very quiet Friday/Saturday. This is completely usual.
There were some great answers posted by 19fieldsm, Alan, Lexiie96 and samgelinas.
19firldsm (meggy) and lexiie96 joined us today. Welcome to Web2.0calc forum. We hope you like it here.
Each day about a half dozen member join up. I usually only mention the ones that make posts, but you are all very welcome here.
I know there are members who are here regularly and never or rarely make posts. I get the very occasional post or private letter where people tell me how much they like to watch and learn from other people's posts. Some of these people, although I am sure not all, struggle with English. If you are one of these people, I think that is great.
Enjoy your weekend or what is left of it.
Melody.

Hi all,
A super quiet day today.
Great answers from Bertie, Alan and I like Serena.
I also received a very nice thank you from mathbrain13.

Someone did ask if the Web2.0 calc can be set to give large answers in scientific notation.
http://web2.0calc.com/questions/how-do-i-display-large-answers-in-scientific-notation
I had a look and I can't see how this can be done but I thought someone else may have an idea.
If anyone works it out, please let us know. I don't know how to use many features of the calc or the buttons above the smilies.
If anyone gains knowledge on these matters could you please teach the rest of us. Thank you.

It appears that the witticisms of C.L.Dodgson (Lewis Carrol) and George MacDonald must now come to a close. Having been discovered in this current day time warp by the illustrious Alan, it now appears prudent for them to return to their real world of the 19th Century. Math Laughter will have to find his entertainment elsewhere. Our guests must pass through Alice’s looking glass. Their ‘time’ awaits them on the other side. They will be missed.

Hi all
Another quiet Sunday/Monday
There were some great answers from reinout-g, ifrogot1 and mathlight and Alan. Thanks folks.
Alan, I am really impressed with your contributions. Thank you.
Reinout-g, thank you so much for taking charge of the puzzles and recreation posts. I consider them as a really important extension to every day 'school' maths. Whatever you can do to generate interest will be greatly appreciated.

I recieved a reply email from Andre Massow today outlining his intentions for development of the forum. Andrew Massow is the sole designer and operator of this website.
This is a quote from his letter.
"Thanks for your great eMail.
I am currently redesigning the question forum from scratch and you will be the first to see the prototype in the attached screenshot.
As soon as an working prototype is ready, I will send you an exclusive link so that you can have a look at the new features."

I am sorry Reinout-g but he did not mention your request. Maybe after he does these upgrades he may have time to look at requests such as yours.

I intend to reply to this email in the next day or two.
These are some of the thoughts that I am having.
1) I would like moderator rights. The main reason why I want this is so that I can remove really offensive (non-mathematical) material immediately.
2) Codeybarr30 only post unsolicited advertising and it would be more appropriate to de-register them than to give them posting recognition.
3) People who have not posted for a period of 2 months or so should not be included as top answerers. There are 2 members on this list that I have not even heard of.
4) I would really like a check-a-box thank you system to be introduced. This is a feature of other forums and it has a lot of merit.
5) Instead of stating the number of answers, it would be more helpful if the names of the answerers were given. Also, who posts the 'finished' tick?

I also want to talk to Andre about the possible problems with the calculator and see if we can get formulas etc easily from the calculator to the forum.
It would be good if we could have ongoing communication regarding the calculator and its development.
I see that Andre has overcome the problem with the ad blocker. The advertising is necessary for fund raising and the ads are not intrusive. (They are in the calculator section)
I had requested an extra page or two, for information posts etc, but I think Andre does not want to do this and it is not vital to us.

Would any one like to comment on or add to this list ?
You can post on this thread if you have something to add, OR I will make a new post in the body of the forum and you can post there if you prefer. OR You can send me a private message if you prefer to.

This is the attachment screen shot.

Good evening all,
I was busy today but there is nothing out of the ordinary to report.
Some great answers were posted by Alan, reinout-g, Rom, Princess Sopie E and guests. Thank you.
I think that is it.
Enjoy the rest of your day.

Hi all,
Another busy day today. Lots of fabulous answers from reinout-g, Alan, scrutinizer, Statman74, Dms, Alexandra and Rom. Thank you so much.
You know, when I wake in the morning and find all the night questions already answered it makes my day so much more pleasant. Thank you.
Monkey Spanker also answered one but an answer is no help if it doesn't come with some sort of an explanation. I'm sorry but it is the truth.
Both I and Superextremebro tried our hand at one of Reinout's puzzles. I know mine is wrong. I already had it up before I realized so I left it there.
Anony gave a nice thank you too. We always appreciate good manners.

Now, Dms dropped in and hugely impressed Reiner and me. He implanted LaTex into the forum and we want a lesson (or 2) on how it is done.
Please Dms, won't you come back and show us?
If you would like to take a look, this is the thread.
http://web2.0calc.com/questions/math_1546

I nearly forgot. I sent the email off to Andre Massow. I have already briefed you on its content.

That is it for my evening.
Enjoy the rest of your day.

Hello all,
Many great answers were provided by Alan, reinout-g, I like Serena, guest, Mathgirl, Rom, JeanLand JimMath.
One of our guests gave a very nice thankyou. These are always appreciated.

This is Mathgirl's first day with us. We welcome you and we hope that you like it here.

If you use acrnyms in your answers could you please make a point of explaining what the letters stand for.
People do have to become familiar with many acronyms but they may not be familiar yet. Sometimes an explanation of what the words mean is also a good idea.

Reinout-g and I like Serena have been investigating possible LaTex editors. ILS has said that 'mathjax' is probably the best because it is usually used in other forums.
Reinout seemed to think that the Latex could probably be delivered via a [tex][/tex] box. Do you think that this is how it would be ILS? Also, do you know if mathjax is freely available? I am unlikely to sell the idea to Andre Massow if there is a cost involved. Reinout, do you have any more to add? I have bumped up the LaTex thread so if anyone has anything to say please add it to the thread. Once I am sure of what to ask for I will send another email to Andre regarding Latex. I have already sent 1 backup email to the original reply and I am concerned that if I send too many they will not be considered or even read. Latex is important to us so I will send the email. I just have to make sure it is right first.

If anyone, would like to learn LaTex, a show of interest is all it takes and we will be very happy to help you learn.
Even without the LaTex editor we use Latex regularly, almost every day I import snips from ouput that I have created with Latex.

That is it from me,
Enjoy the rest of your day.
Melody.

Mathjax (see https://en.wikipedia.org/wiki/MathJax) is open source software that uses the Apache license:

The Apache License (/əˈpætʃi/) is a free software license written by the Apache Software Foundation (ASF). The Apache License requires preservation of the copyright notice and disclaimer. Like other free software licenses, the license allows the user of the software the freedom to use the software for any purpose, to distribute it, to modify it, and to distribute modified versions of the software, under the terms of the license, without concern for royalties.

So in other words, yes, it is free.

If it is installed in the web site, we could type latex with [tex][/tex] tags around it. Possibly with alternative tags like dollars.

Good evening/morning all,
Thank you I like Serena. I will put this into an email and send it to Andre Massow over the weekend. It is already weekend for me.

There were a LOT of questions today. Forfunately a number of people also provided excellent answers. These peple included Alan, Dms, Rom, guest and Bradley. Thank you.
P6fitz joined today and gave me a very nice thank you for my answer. Welcome to web2.0calc forum. We hope you like it here. And, thank you, we aways appreciate good manners.

There is just one unanswered question on t tests. I have left the address on the usual marker. ('All questions answered except' thread)

Good evening all,
I had almost the whole day off. Many thanks are extended to Rom, Dms, Alan and mtho for this.
I think this was the closest day to a holiday that i have had since I joined on 28th Sept 2013.
It was wonderful to take a break and to know that the forum was left good hands.

idkman joined today. We welcome you and we hope that you like it here.

Unfortunately there was a case of extreme rudeness today. It is most unforunate when this happens.
The fact that people can post without becoming a member first makes this type of behaviour much more likely to occur.
It is a real pity. My sincere appology is extended to the person involved.

Thankyou ILS and Dms and reinout-g for you contributions towards Latex. I have yet to contact Andre Massow.

That is it for this Friday/Saturday.
Enjoy your weekend.
Melody.

Hi everyone,
The week is starting to liven up. There were some great answered supplied by Alan, I like Serena, Bluefrog and kitty<3. Thanks you.
Brainiebean123 joined today. Welcome to Web2.0calc forum. We hope you like it here. Looking at the posts that you made today I think you and reinout-g might get along well. He likes providing puzzles, Maybe he can find some that you like.

Information for new people.
There is a private message system here. If you left click on your username you will find it. If you go into the user control panel then Board Preferences, you can get a pop-up display for new messages, that is if you wish to do so.
If you send a message it will sit in your outbox until the recipient opens it. In the mean time you can edit it or delete it if you wish. It only moves to sent mail after the recipiant opens it. It is a really cool system. i wish my usual email worked this way.

I sent another email to Andre Massow today regarding Latex. My letter was very similar to the one i presented to you two days ago. I also reiterated my need for moderator privileges. The detritus around here really needs to be cleaned up. I would not abuse any privilege that I was given. I would be encouraging core members to help mould conduct policies. Anyway it is all irrelevant at the present time .

I think that just about sums things up on this Monday evening. I just realized, it has been Sunday in many places. My the place is getting busier.
Anyway, enjoy the new week.

Hello everyone.

I have not answered any questions today. Most of the sensible questions have been answered. I have Dms, Rom, ezom and ChrisP to thank for this.
ChrisP, you are not a member and I have not noticed you here before but you have answered many questions today and I thank you.
I have noticed that when one person leaves there is usually someone around fairly quickly to take their place. However, the forum is growing and we do not want to, and really cannot afford to, lose our valuable people who answer questions.

This is a sad day for me.
I am distressed at the abuse that my fellow answerers have yet again been subjected to via this person who calls himself a professional Troll. This has been going on for a while now but the frequency of it is escalating. I am not responsible for this, and there is nothing I can do about it but that does not make me feel any better. I extend my sincere appology to the people who have been targeted.

What's the best definition of an internet troll?
“A computer user who constructs the identity of sincerely wishing to be part of the group in question … but whose real intention is to cause disruption and/or trigger conflict for the purposes of their own amusement.”

Hi all,
I have recovered from my yesterday's collapse. I thank those people who voiced there support (by private message). I really needed to hear it and I am very grateful.
It is thought that the best way to deal with our 'Professional Troll' is to ignore his/her posts. No response = No fun for the troll.
I guess this forum can cope with 1 rude adult without falling in a heap.

Today was a standard busy mid-week day. Fantastic answers were provided by Reinout-g, Alan, Dms, Samgelinas, Ironn, Mathcalc, ChrisP and unknown.
NerdPro also answered a question but it was answer only with no explanation so it was not very helpful. Sorry NerdPro, I am pleased that you answered but you do need to explain the answers that you give.

ChrisP, it is great that you are answering so many questions. We'd really like you to consider joining up. There are a number of benefits and we would love you to join us formally.
Look here to find out what benefits there could be for you.
http://web2.0calc.com/questions/become-a-member-why-would-you-want-to

Alan sent an email to Andre Massow yesterday. Andre responded and said that moderator rights will be a feature in the new forum design. Andre also said that he was hoping to publish a new Beta version upgrade this weekend so that we can all evaluate it. I am not to sure what that means. I guess we will find out.

Oh there was a question today with notation that I haven't seen before. It was in here http://web2.0calc.com/questions/quads It was just m<ABC which meant measurement of angle ABC. I had no idea what the 'm' meant. Chris knew what it meant. Is it normal notation? Could any comments please be posted on the end of the relevant thread. Please don't post here.

That's it for this Wed/Thurs,

Jedithious left a very nice thank you for Chris. Jedithious has been with us for a long time, he has always had great manners.
Jedithious, I'll have to introduce to Reinout, he might be able to tempt you with some puzzles.

I'd still like an answer to my yesterday's question. It was directed mainly at you Chris. I just want to know if it is usual notation or if you just used your powers of deduction

Hi all,
Today was extremely quiet - even considering that it was a Saturday/Sunday.
Anyway there were a couple of good answers from CPhill, Rom and guest. Thank you.
pas967 also answered a question correctly, thanks for that, but you gave no explanation so it probably didn't help any learning take place.
There were also nice thank you's from a guest and from 'Form one Malaysia'.
Form one Malaysia became a member today. Welcome to the forum, we hope that you like it here. I don't think that we have many members from Malaysia.

It is common for answerers to become frustrated by the lack of effort shown by many people who ask questions.
I often answer question in great detail BUT to some extent I do agree with 'I like Serena'. Sometimes less is better.
Students should be encouraged to use the formulary page or google to find formulas etc. We usually answer quite quickly so I think that it would be very appropriate to ask students to go away and come back with a little more input - such as a formula and/or an explanation of why they are having difficulties. Even if we are given this input it is still not necessary for us to answer questions in full. The student will learn better if they have to do some of it themselves. I guess I am saying that we should be offering guided learning rather than just answers.
If you want to answer in full, that is fine. I know that I will sometimes. I just want you to think about possible alternatives.

Thanks everyone,
Melody.

Hi everyone,
Today was really busy Monday/Tuesday.
The following people all answered questions.. Alan, CPhill, reinout-g, Samgelinas, Tolkerism, Dms, The_math_Bro, mathwiz, Mighty, mit, abc, and Bob Wright. That is 12 different people. I think that is a record. Thanks so much guys.
There was also a nice thank you for Rom from Ddk.
Our Wood Chuck theme has been revitalized. (though I don't think that any one has actually answered the question yet)
Here is the Wood Chuck thread. http://web2.0calc.com/questions/viewtopic.php?f=2&t=9752&p=21401&hilit=wood+chuck#p21401
We had some fun with this theme a while back. I've tacked the address of the old thread on the end of the new one.

CPhill introduced me to Heron's formula, for finding the area of a triangle and Alan provided the proof so now I have some homework. Thank you Chris and Alan.
Here is the thread if anyone is interested. http://web2.0calc.com/questions/viewtopic.php?f=2&t=9757&p=21453&hilit=heron#p21453

Good evening all,
I think that may be the first day where we had more than 1 page of questions!
Great answers from Alan, Samgelinas, highschooler, Rom, CPhill, hihihi, Snipesgaming, guest, and Kitty<3. Thank you.
There were a couple of others as well but since they came without working, they were not of much value.
There were also a couple of nice thank yous given from Zack7713 and a guest. We always like it when people show their appreciation.

I purposely did not answer many questions (I tried not to answer any) on the first round. I think it is more important for me to:
a) check that all proper questions receive answers.
b) check as many of the submitted answers as possible and to input only when I want to add something. I hope no one gets offended by this.

Today, I was busier than I really wanted to be. There are a couple of answers from Chris that I really want to learn from but it will have to wait for a less busy time.

There was a probability question that Chris (CPhill) and I both answered and we did get the same answer. However, neither of us is very confident with our probability ability and I would like someone who is confident to check the answer please. This is the address. http://web2.0calc.com/questions/probability_18

I think that is finally it for this Tuesday/Wednesday.

Hi all,
There were lots of great questions and answers on this busy Wednesday/Thursday. The answers were supplied by Samgelinas, CPhill, Epos_Metallicus, guest, Nobody Special, The Boulder44, babyy, Rom and I like Serena. Thank you.

I might take this opportunity to remind our illustrious mathematicians that most of the people in this forum have not heard of complex numbers. It doesn't do any harm to give complex answers, it is fun for us, and I think it is good for people to get a glimpse of what may be in store if they take mathematics to a much higher level. HOWEVER, you do need to consider who is likely to be asking the questions - it is their question. Your FINAL answer should be aimed at that person. At school the normal acceptable answer if only complex roots are available is "There are no real solutions".

See you later,
Melody.

Hi all,
It seems the questions are already starting to thin out for the week.
Still there were lots of great answers from Rom, Samgelinas, CPhill, Alan, Hello, ifrogot1 and Pasc. Thank you all.
Amber6198 also gave Rom a nice thank you. It is great when people show their appreciation.

I am still very keen for everyone to make the best use of the buttons above the smilies.
I think the 'sub' and 'sup' buttons are especially important - they make questions and answers so much easier to read!
I wrote a post a couple of days ago to explain how to use these buttons. I think some people could add to this as I actually don't know how to use them all myself.
Could everyone please read this post and learn from it or add to it if possible.
http://web2.0calc.com/questions/viewtopic.php?f=2&t=9695&p=21263#p21263
The easiest way to get to the post is to highlight the address, left click and then choose 'goto' from the drop down menu. (you can just copy and past the address into your browser if you prefer.)

That is it for this Thursday/Friday
Thank you
Melody.

Hi Everyone,
Today was another quiet Friday/Saturday. Still as always there were some great answers forth coming. These answers were provided by CPhill, Samgelinas, alan guest, Bertie, Stuff, and Rom. Thank you all.

I have been asked to give some guidance on question and answer presentation. I will do my best.

1) Make full use of all the buttons above the smilies. I have done a separate post on this and I spoke about it only yesterday. This is a quote from yesterday’s wrap:
"Could everyone please read this post and learn from it or add to it if possible." http://web2.0calc.com/questions/viewtopic.php?f=2&t=9695&p=21263#p21263

2) We are slowly learning how to bring Web2.0 calculator outputs into the forum. This is also covered in the above post. Alan was extending my knowledge today. Thanks Alan. He displayed a trinomial factorisation, an indefinite integral and a definite integral all outputted from the web2.0 calc. I have included these in a new post in the above thread. The input is written under the output so they should be self explanatory but if they aren't then let me know and I will help you work it out.

3) If you want to add symbols such as an integral sign, these can be copied from other places and pasted in. Sometimes I will open a new window and then open this page within it http://www.rapidtables.com/math/symbols/Basic_Math_Symbols.htm. It is a list of mathematical symbols. I let the symbols occupy half the screen and the post occupy the other half so that I can gather the symbols as I need them. You can also do this using the Microsoft character map but I often find the symbols in there to be very elusive. I am sure there are many other places that symbols can be gleaned from.

4) I very often include attachments in my posts. These are almost always collected straight from other screens using the Snipping Tool. The Snipping Tool is included automatically in Windows 7 and I assume in Windows 8. I save the output (as a jpg) and then upload it to the forum. I file these under date and name so they are always very easy to find. The name of the upload is included in the post under the attachment so you can see how I store it if you want to. Anyway, I just upload these jpg files as attachments. This might sound like an ordeal but once you get used to it is really very simple.

5) Sometimes I will write a program in LaTex. I will then use the Snipping Tool, to snip the output that I want, and upload it as an attachment. You can save the output directly from the program but it is stored as a pdf file and these cannot be uploaded as attachments. I suppose that they could be converted to an acceptable file form using some conversion program. I have wondered about this because if the output was too long my method would not work very well. So far it has not really been a problem so I have not worked it out. Maybe someone would like to add input here.
Some people probably use MathType instead of LaTex for this purpose.

6) When I draw geometry things, I use GeoGebra which is a free download. This also has a simple version of latex built into it. (I think you can actually turn the picture into LaTex code but I haven’t worked this one out yet.) You don't have to use the LaTex but it is handy sometimes. Again, I collect the output using the Snipping Tool. My knowledge of GeoGebra is not great, I am using the ‘trial and error when I need it’, method of learning.
There are many other geometry programs out there this is just the one I use.

7) We should always try to use the Web2.0 calc output whenever possible but sometimes I also use 'Wolfram|Alpha calculator' and 'Desmos Graphing Calculator'. Both of these are very powerful tools. The output of these can be bought in via the Sniping Tool or via the web address.

8) This is not really relevant in the body of the forum but if you want to send someone a picture in the private message section. I don’t think that you can upload an attachment. I would use a tool called Gyazo for this. It is another free download. It is used like the snipping tool only instead of storing the image as a jpg it stores it in the ‘cloud’ and supplies you with the web address.

I don’t understand hardly any of this technology but it is all very cool.

That is all I can think of at the moment. I would love for other people to further extend my knowledge in these areas.

It is weekend for everyone now.
Enjoy what is left of it.
Melody.

Hi all,
There weren't many questions today, it was Saturday/Sunday after all but there were still lots of great answers provided by CPhill, Radamus, Kitty<3, Alan, Millie, Rom, Reinout-g, Dms and Peter. Thanks folks!

Every day there seems to be one or two more people offering solutions. I think that this is great! It has always been my philosophy that everyone should be encouraged to join in. If you are not sure if your answer is correct you should say so BUT I think that the person who asks the question needs to accept some responsibiliy for deciding whether to accept or reject another person's offered solution. Also, almost all answers, especially lower level ones are checked by other more senior mathematicians so very few wrong answers will escape detection. If you are not happy with the answer you are given you can always 'bump' your own question and ask for someone else to take a look at it, but it may be to your advantage to wait a little while first.

Nobody Special has attempted one of reinout's puzzles. I am really pleased, I wish more people would show interest in the puzzles. Reinout is not always around so you may have to wait a little while for him to comment on your answer.

Today Reinout 'proved' that 1=2. He was illustrating what can happen when you accidentally divide by 0. I thought it was great!
This was the thread. http://web2.0calc.com/questions/i-need-help-with-this-ecvation

Information for new people - Private Messages.
There is a private message system here. If you left click on your username you will find it. If you go into the user control panel then Board Preferences, you can get a pop-up display for new messages, that is if you wish to do so.
If you send a message it will sit in your outbox until the recipient opens it. In the mean time you can edit it or delete it if you wish. It only moves to sent mail after the recipient opens it. If you delete the message the recipient will still get a message but it will just say 'message deleted before delivery' It is a really cool system. I wish my usual email worked this way.

That is it for today.
Enjoy what is left of your weekend.

Hi,
That was the quietest day that I can remember!
There were a couple of good answers provided by Alan. Thank you.
Bertie responded to reinout-g's puzzle. So now reinout has two answers to check.
Reinout signed up to Sporcle (A game site that I suggested) I am very pleased about that.
Nobody Special, who has been here for a very long time, finally became an official member. I am really pleased about that. Thanks Special.
It is now Monday or Sunday evening everywhere in the world so I am expecting tomorrow to be much busier.

Hi all,
Ok I was wrong. It was another very quiet day.
I even looked up world holidays to see it that was the reason. It was a holiday today in Maryland (US), Azerbaijan, Cyprus, Greece and San Marino.
Dms comes from Greece but I don't know if any other contibutors come from those places so I guess it is just a conincidence.
Anyway we did have a couple of good answers from Alan and Princess Sophie. Thank you.
That is it for this very quiet Monday/Tuesday.

Melody · Answer 81 · 2014-03-26T08:39:06

Hi all,
Another quiet day. Where have all the young people gone?
There were a number of high level questions with great high level answers.
Answers were provided by CPhill, Rom, reinour-g, Stu, Bertie, Alan, I like Serena, Samgelinas, anonymous1, and PhDSmith. Thank you all.
Dr. Smith became a member today. Welcome to the forum, we hope you like it here. I wonder if you saw my 'Lost in Space' post recently? It wasn't there long, I deleted it. So maybe not.
The only question not yet answered is the Hyperbola Proof by CPhill.

A note mainly for the younger people:
I am wondering why there are so many less low level questions the last couple of days than I would normally expect. Lower level questions are very welcome here. Don't be intimidated by the harder questions. I want this forum to be available, useful and friendly for all ages and abilities. Some of the other mathematicians have told me that that is what they want too. If you are not completly happy with an answer, please tell us. You can tell us that you don't understand any of it, or some of it. You can tell us that your teacher does it differently and then we will try to show you your teacher's way. We like to get feed back. You can help us to learn the best ways to teach.

That is it for tonight.

Hi everyone,

Great answers were provided today by Rom, Alan, Samgelinas, I like Serena, Bertie, guest, CPhill and KasiKazuto. Thank you.
Thanks were given by Princess Sophie, Jannina1514, and Pewface111. Pewface111 was so overjoyed that (s)he offered Chris (CPhill) 'diamonds and love'. That is pretty impressive.
Jennina1514 joined up today. Welcome to the forum. We hope you have many positive experiences here.

I usually refer people to a wiki formula page when I answer log questions. Today Alan showed me that these are available in the formulary section on this site. Thank you Alan, we all need to be taught and encouraged to use the features that are readily available in the web2.0calc site. This site has many great features that we, as a group, are still discovering.

Thank you to the guest who contributed the previous post on this thread. Apparently non members have been having trouble submitting new posts. They are also having problems registering.
Perhaps this is why there have been so few questions this week. There have been a few of non-member posts today, maybe the problem has been rectified. I hope so! (This time last week there would have been twice as many posts) Anyway, I will write a note to Andre Massow, the site developer to let him know of the problem. There is nothing more that I can do, I am sorry. Hopefully this problem will be rectified very soon. If anyone knows of ongoing problems could you please keep us informed so that we at least know that the problem is continuing.

If any of you have different thoughts on why the question numbers are dropping or how this problem can be overcome, please share your ideas with the rest of us. You can post on this thread if you wan,t or you can start a new thread, or you can discuss it with me by a private message.

That is it for this Wednesday/Thursday.
Melody.

P.S. I just emailed Andre Massow to notify him of the problem.

Melody · Answer 84 · 2014-03-28T09:06:19

Hi everyone,
There is a lot to report this Thursday/Friday.
Firstly Andre Massow replied to my email and says that he thinks he has fixed the posting problems that people have been having this week. Today there have been many more lower level posts so that is probably the reason. Thank you again to the guest who notified us of this problem. Your exact wording also help Andre pinpoint the problem.
Great answers were delivered by CPhill, Alan, PhDSmith, Redtriangle, Bertie, Samgelinas and Rom. A big thank you to each of you.
Thank yous were given by Ineedhelp, notsomathpro, and Ohnonotmaths. We really like it when people show their appreciation.

We had 8 new people join today (at last count) I don’t normally do this but I have sent each new person a welcoming message. If you left click on your username you will find the message centre. Just click into it. Anyway, welcome to the forum. We hope you learn lots and have fun here.

Web2 BETA Version.
Andre Massow has allowed me to view the beta version of the coming new web site. I should explain to new people that this will be implemented sometime in the foreseeable future. It is not a full working site yet but many of the features are already working. Many of you will be thrilled to know that Andre has included LaTex as well as a Math Formula button. These features will be fantastic. I’ve already sent Andre a letter discussing some of the more obvious pros and cons.
It appears that Andre has omitted the icons in the margin, this is a real concern to me, it is the only way that we can readily recognise info posts etc. I have asked if they can be reinstated. I have also asked if it would be possible to ‘freeze’ some of our info posts at the top of the first page because they are going to disappear very quickly otherwise. This is because there will be a lot less posts per page.
I don’t know is Andre can or will do these things but at least we are communicating.
Here is a little look at the proposed new post page.
140328 beta version new post.JPG

That is probably enough of a wrap on this very wet Sydney evening.
See you next time.

http://web2.0calc.com/questions/someone-should-animate-this

The last couple of weeks the forum has been shrinking. Three weeks ago there were many more questions.
At present there is so little happening that I see no point in doing a wrap every night.
I don't want the information posts to 'fall off the page' So I may only do a wrap when this is imminent or when I have something particular to say.
If anyone wants to comment on this in the body of the forum or by private message your viewpoint will be welcome.
I have no objection to doing the wrap every night but at present it just does not seem to be justified.
Kind regards to all,

Hi everyone,
My last wrap was 3 days ago. I was not really intending to do one tonight. The regular posts were about to 'fall off the page' and I was seriouously considering leaving them there.
Anonymous4338 made me re-think. Thank you for your post on this thread. I am glad I made you happy. You have made me happy too.

Since my last wrap many great answers have been posted by Samgelinas, CPhill, Alan, Kitty<3, reinout-g, brabrams, guest, Rom and Anonymous4338. Thank you.

Samgelinas posted an addictive web game. Thanks for that. I have added the thread address to my collective 'games' thread.

I have written a post 'Information for new members' on the 'Become a member' thread. I have talked about a few things there, I can't actually remember what - You will have to take a look.
I have however explained how the private message system works. Unless you have any particular reason not to, it would be a good idea if you set an alert pop-up for new messages.
I have explained it all in the post. I sometimes want to contact members privately. This is the only way I can do it. Other people may also want to chat.

I like the end of the day wrap up because it is usually there when I open the forum (which is usually around 2pm.)

It saves me the time of skimming through all posts which happened during the night (such as someone who gave an interesting theory or answer and also might remind me to eg. update the probability puzzles (which I totally forgot) or have another look at the calculator options, etc. In addition to that it gives me an idea of when you're about the log-out, which is usually when I refresh the forum a little more often.

Moreover when I first came to the forum it also motivated me to answer more questions since it kind off felt like an achievement to be in the wrap up.

Nevertheless I do understand that the forum has become less active and that it might be too much to post one every day.
Perhaps you could post one every once in a while just for the update.

Reinout

Thanks for the end-of-day wrap, Melody!

It really helps me to catch up on what's happening in the forum, especially when I've been busy for a few days.
Thanks for taking your time to write it for the longest time EVER!

Melody · Answer 93 · 2014-04-07T12:28:11

Hi all,
First I would like to thank Kitty<3 and reinout-g. for their public support. Other people have also offered considerable support using more private means. I thank you all. A wrap is probably not needed every day but it does help bind the forum into one. I know that I am usually the only one that writes here but I do always read what people post and I try to listen to what they are telling me. I also use the private messaging quite heavily and that adds to my understanding of what people want from their forum.
We now have a number of mathematicians enjoying the forum. They are all really nice people. All of us want this site to be friendly and helpful for everyone. It makes no difference what level you are studying at. Anyone who wishes to post a mathematics or arithmetic question or mathematics idea is very welcome here.

Maybe I have left it a bit to long to write a wrap, there is a lot of things I want to say and I don't know where to start.

Okay, the credits. There have been lots of great answers in the last three days. These were offered by Alan, CPhill, reinout-g, Anonymous4338, Rom, Kitty<3 and I like Serena. Thank you all!
I was particularly impressed with a couple of the posts that Anonymous4338 wrote. Your explanations are really good. Keep it up!
Breezycream gave Chris (CPhill) a fantasic thank you.

I like Serena found an internet site which looks rather interesting. It was offered on a thread titled 'Graphing Conic Sections' thread. I haven't looked at it very well yet. I have added the address to my 'Information pages worth keeping or developing' thread. Anyway, this is the site. http://www.intmath.com/plane-analytic-geometry/parabola-interactive.php
I think ILS only just discovered it, maybe someone would like to check it out properly and get back to us on its merits. Any volunteers?

A 2+2 thread took on a life of its own. It has been around for a while, a number of people have played with it. Sometimes these light hearted posts add an element of fun to the forum. I do not want this forum to be too serious. It is great to see both adults and children 'playing' with light hearted posts. This is the thread. http://web2.0calc.com/questions/me-stupid

We have had a few puzzles posted. Reinout posted a couple on his probablity thread. http://web2.0calc.com/questions/probability-puzzles
And Bertie posted a mind bending money problem. http://web2.0calc.com/questions/a-money-problem

There was also a post where LaTex was discussed. I want to do a proper post on learning LaTex, but I just haven't gotten up to it yet. If you would like to learn LaTex, there is some information given towards the end of this thread. http://web2.0calc.com/questions/derivatives

Lately we have had some problems with unpleasant posts. Please, do not respond to these. Just ignore them. Any response gives the poster the attention that they crave. Responses also mean that the unpleasant post is bumped back to the top of the forum. Please do not respond, just allow the posts to pass into obscurity as quickly as possible.

That is enough for one night.
Thank you everyone. This forum belongs to all of you and you are all responsible for making it a great place to 'hang out'.

Hi all,

Well, our forum finally has its new look!

Chris has pointed out that there are lots of bugs at the picnic and so far my spray can of pyrethrum is not working.

We have no member section, private messaging is not working, the preview is not working, we cannot copy and paste within a post (using right click), some of the displays are not working properly. These are just some of the problems. Hopefully Andre Massow will fix these problems very soon. I am sure he is doing his best. I expect it is a very onorous task.

Hopefully it will come together a little better tomorrow.

I will do the credits next time.

Tues 15th April 2014.

Hi everyone,

And, the questions just kept coming. It was just starting to get this busy a few weeks ago but then the forum went deadly quiet. Now suddenly the questions are coming think and fast. Why is that? Was there a problem with the old forum that was blocking posting or is it just a strange seasonal phenomenon? Maybe Andre knows, for I do not.

Anyway, there were lots of great answers from admin, Alan, (Chris and CPhill - another twin?), Bertie, yanes27, reinout-g, SpawnofAngel, deriam2kgmailcom. I thought Kitty was there too. Thank you everyone. You all do a great job. Over the last few days I am especially thankful to you Chris. There is no way I could have coped without you.

There are a lot of new members as well but i haven't been able to keep up with you all. Welcome to the forum. This forum is in the middle of a very comprehensive overhaul. It is slowly coming together. The site's designer Andre Massow is working long hours to try and remove the bugs and polish the final product. There is still a lot to do but over the past 48 hours it has vastly improved and I am sure it will continue to do so for a while yet. The private messaging is still not working. That, I believe is his main task at present. Thank you Andre.

The main forum tab is sorted on start date for the thread. Now Andre has introduced a new tab where the most recent posts are sorted on post time. This is something that the answerers really wanted but I think it needs to display more than just one page. A page may only reflect a few hours activity.

I now have some moderator privileges. Thank you Andre. I don't really understand them yet but I can make a post invisable to the rest of the forum and I can give a green tick to indicate when a question has been well answered. If I tick a question I am not sure if it can still be added to. Plus when I do this numbers get allocated and I don't understand their significance. I have ticked a few posts and Andre has also ticked some. Anyway it will take me a while to work out how to best use these privileges and in the mean time I will continue to use many of my old techniques. Any guidance from you will be appreciated.

I am sure that there are many more things that i need to discuss but I cannot think of what they are at present.

Good night/day.

Melody.

The bugs are slowly being erradicated from the picnic that is web2.0calc forum. Hopefully the members section and private messaging will be working soon. I am also hoping that we will be able to post attachments in the not too distant future.

That is it for this Tuesday/Wednesday.

Melody · Answer 100 · 2014-04-17T12:07:15

Hi everyone,

There is no way I can go through all the questions and answers like I usually do. There are just too many. I have ticked many of the questions that I think are fully answered. I am reluctant to tick my own answers unless I think someone has checked and given me a thumbs up or written acknowledgement of my accuracy. I think that you all have the ability to give a thumbs up or a thumbs down to any answer or question.

I am also reluctant to finalise questions when the answers are over my head. Unless another trusted answerer has checked (mainly for careless mistakes)

Andre has told me that he intends to eventually show the name of the last answerer - like how it used to be. It will be easier to check answers then.

Rom is back with us again, he said he thought the forum was down, the address is different now. I am wondering if Samgelinas is absent for the same reason. Can anyone contact him?

-------------------------------------------------------------------------

At the moment these are what I see as the biggest problems. (I hope that Andre Massow is reading this)

I know that some of you would have different priorities.

**I hope that the member section and messaging system are working soon. The forum cannot function properly without these. People can contact me at melodymathforum@gmail.com

**I love having LaTex on the forum but I cannot answer to my usual standard because I cannot upload attachments. Also, when I try to use old information threads, the attachments do not display so they are useless. This is very frustrating.

*There is no preview facility.

*The input=result is not working

Thank you everyone. There are still a lot of problems but many others have already been fixed and I know that Andre Massow is continuing to work long hours to eradicate the ants and iron out the wrinkles. We just need to be patient.

Enjoy the rest of you day/evening.

Melody.

Melody · Answer 101 · 2014-04-18T11:32:50

Hi everybody,

Once again we were swamped with questions. Reinout wrote me a letter yesterday and these are his words; "It seems like I'm trying to empty the sea with a bucket." I hope you don't mind me quoting you reinout. The fact is I was feeling the same way. Reinout's words helped me to formulate a strategy.

This is my view;

Members must get priority. Their questions should be answered as quickly and as comprehensively as possible. Anonymous postings should be treated much more casually. Only answer them if you have time and want to do so.

Could people please use the thumbs up and on occasion the thumbs down symbols when viewing other people's answers. I do not want to be the only one to decide if an answer is good or not. sometimes I do not even have the knowledge to do this.

Obviously all answerers are here because we like answering mathematics questions but the forum also has to be fun for us. We need to allocate time to light hearted banter and to group discussions on interesting topics. We need to be able to play with or learn from some the questions and answers that are presented to us. We can not do this if we allow routine answering to take up all our time.

Just prior to writing this wrap I posted a note saying 'All members questions have been answered' This will be my new wording for such posts.

I am sorry, I have not prepared a list of credits. There were many great answers and I thank you all.

------------------------------------------------------------------------------------------------

I thought you might like me to include a few posts that you may find interesting.

These were a question (posted twice) and 2 answers that appealed to me today. I want to give them both more considerations. The answers were from Rom and Chris. I think the answers are similar but I haven't really thought about them properly yet. Thanks guys.

--------------------------------------------------------------------------------------------------

Some people will find this one interesting

Reinout enjoyed this puzzle question. I took time out and enjoyed this puzzle as well! It is not super hard - why don't you take a look as well?

--------------------------------------------------------------------------------------------------

Hopefully more of the forum features will be working soon.

Thank you all. For the Christians amoung you, Enjoy your 'Good Friday' or what is left of it. Oh, that sounds a bit prejudicial. I want everyone else to enjoy their Friday as well.

It is nice to see that someone other than me and admin is using the thumbs up system. This is just a way for you to say that you appreciated an answer. I would really like people to make more use of this system that Andre has set in place for us.

Andre now has a basic messaging system working for us. This is great, thank you.

Andre has also changed the second tab to 'Answers'. I haven't used it yet so I can't comment on its merits. Sorry.

--------------------------------------------

I think I liked this question and answer (by CPhill alternatively known as Chris) best today.

I also want to look at this answer by Alan, The first line is obvious but after that - I have to think about it.

And lastly this question by CountryGirl333 gained a lot of attention. CountryGirl interacted with answerers and this is always appreciated. Thank you CountryGirl333 It is good when we all get to interact with each other.

I am not at home at present and my access to the internet is poor. If I am quieter than usual that is probably why. Rural Australia has poor internet access. Although I am on the coast, not inland, so there is at least some coverage.

That's it for this Easter Sunday day/night.

The messaging system is now working in a very basic way but you can still email me at

Hi all,

There have been a LOT of questions. All member questions have been answered. Most, but not all, of the anonymous questions have been answered - there simply has not been enough time to answer all. Members must get priority. It is easy to join up and priority answering is one of the benefits.

Great answers were given by BlindxD, CPhill, reinout-g, Alan and CreeperCosmo. Thank you all. I hope I haven't left anyone out.

Old inbox messages have now been restored; thank you Andre. Old outbox messages are not restored yet and there is no way to delete messages. I have received many messages and I have responded to very few. The messages that I have sent are not displayed to me (because there is no outbox) so I am not keen to contact people this way. I would prefer it if people continue to use my personal email address to contact me. I will add the address at the end of this post.

It is now possible to very easily search another member’s posts. But I think this has to be done by clicking on the username. I don't think that you can actually type a username anywhere to bring it up. I might be wrong, I am feeling my way the same as everyone else.

Answerer names are now included on the 'questions' tab page and the 'answers' page. This is great. Thank you Andre.

I think Andre Massow has been experimenting with the second tab 'Answers Page'. This page is not working for me. I would really like it to be displayed much more like it was before the forum got its new look. Today I found a response from a question that was first entered a few days ago. It is only lucky that I saw it. I would like one of the display tabs to be questions sorted on most recent post. To the best of my knowledge, this is what other primary answerers want as well. If anyone would like to expand or comment on this maybe you could post a @@message in the main forum. Andre and I do NEED your feedback. I hope you are reading this Andre. Maybe I shouldn't have mentioned this yet, I know that Andre is already fully occupied with higher priority issues. It is written now so I will leave it - I would like the opinion's of other members anyway.

Tonight BlindxD posted a question which Alan answered. The question became interactive with Blindxd asking for clarification. Thank you BlindxD, this is what we want in the forum. Ask lots of questions and never 'pretend' to understand.

There were a number of fun and chatty posts today. I think that this is great. I do not want the forum to be too serious. The 'I like Turtles' post turned into a fun little thread and I also rather liked this thread.

That is it I think, Enjoy what is left of your Tuesday.

Good day/evening everyone,

Once again there have been a lot of questions and many great answers. These were delivered by CreeperCosmo, CPhill, Kitty<3, Bertie, SpawnofAngles, Alan, Samgelinas, reinout-g, Rom, BlindxD, DavidQD, novice and unknown (do you have amnesia?) Thankyou all, it is great that we have so many members answering questions. Of course some questions are also answered by non-members.

Almost all questions have been answered and I have looked at most of those answers. I have ticked most of them as finished. I do admit that not all of those have been thoroughly checked. I have always taken the postition that the question asker must accept some responsibility for what answers they accept and what they reject. If they are puzzled they should always ask for clarification.

The fumigation has not finished - there are still many bugs but the numbers are slowly diminishing. Thank you Andre. I have been told that the links I put in the wrap, and presumably other links, don't always work. Also sometimes our member page is displayed on the list of answers. Hopefully these and other problems will be fixed soon.

Oh, I have asked a number of times how people are including images, everyone is silent - I finally worked out that they are coming straight from the net. Has anyone managed to include pictures from their home computers yet? Can anyone fill me in better on inserting pictures PLEASE?

I have been answering questions most of the day and I am afraid they have run together and I haven't noted any in particular. There was a post though that I liked because it reminded me of how non-mathematicians really do feel (sometimes) when they are facing a mathematics problem. I thought it was relevant and amusing.

That is it for tonight, enjoy the rest of your Thursday.

Hi everyone,

There were lots of great answers today from Gman2598, Alan, CPhill, Bertie, Kitty<3, novice, unknown and a number of anonymous people. Thank you very much.

I think all member questions and most anonymous questions have been answered. I have checked as many of those answers as possible and given a tick to almost all of them. I am starting to burn out.

There are just too many questions and there is too little time to just 'enjoy' the forum. I am not actually trying to answer any questions but I do want everyone else to get credit for what they do. I know some of you are looking at other's answers and some are giving thumbs up which is great. Maybe you could actually put a short post saying that you have checked it and it is alright - then I won't feel like I have to check and I won't feel guilty about giving a tick when I have not personally checked. This is just a thought.

Does anyone have any other ideas.

I have not responded to a number of messages. I appologise for this. It is partly because the message system is still not very good and partly because I am just to busy with the immediate needs of the forum.

Enjoy the rest of your Friday.

Hi everyone,

It was a little quieter today. It is always quietest on Friday/Saturday's but there were still plenty of questions and Alan, CPhill and at least one anonymous person provided many great answers. Thanks guys.

Andre is slowly pulling the programming of the forum together. There are now many special characters that can be inserted. Plus, today I turned a thread into a sticky topic. This had never worked for me before. I was really pleased, because I was worried that this thread 'Information pages worth keeping or developing' and all the pages it refers to could become lost for all time. I have already made use of it.

Actually I am hoping that reinout uses this to make the puzzles easier to find. I am sure I had a reference thread for puzzles somewhere. We will have to find it.

Andre, you have never indicated whether you read this wrap but if you do there is still a problem with Alan's and my profile pages popping up in the 'Math Answers' pages. At present I am on the most recent page (856) and Alan is on page 855.

I am also very eager for the message system to work properly and I really want to be able to insert attachments from my computer. To the best of my knowledge the old attachments still do not display properly.

Still, the forum is slowly improving. Thank you Andre.

That is it for today. Enjoy what is left of your weekend.

Another busy day with lots of fantastic answers from Mathwizard91472, CPhill, Bioschip, garanceme, Alan, DavidQD, Bertie, and 1or 2 anonymous people. A big thank you to all of you.

There was only one unanswered question on the forum and I am sure Chris will have answered it by the time I finish this post. Andre, Chris has got his eye on the admin score on the 'Top Answerer' board, it shouldn't take him too long to over take! Then it will be my turn to worry. lol

There were also a couple of nice thank yous given today, all answerers really appreciate it when people show their gratitude.

I like this question today. It made me think. Chris and I both invite more comment.

This one also generated interest.

Chris has told me that sometimes these links don't work. There are still a lot of teething problems on the new forum. I think they usually work though. So good luck.

I wrote a letter to Andre Massow and have received a reply - I put these together and they are posted in the forum. Comments and suggestions are very welcome. This is the address. I have also included it with the 'Sticky Topics'

Kitty pulled together a few replies to 'How do I put fractions into the calculator' and put the addresses into 1 post. I thought this was good and included her reply in the Sticky Topic 'Information pages worth keeping or developing' It is on a new last post because I cannot edit the old pages. I presume this is because they were written in the old forum. It really needs to be done a little more neatly. I have suggested that Kitty does this but I don't know whether or not she will. I'd really appreciate it Kitty!

The frac command in the latex was not working properly which was all very irritating. These things are sent to try me/us.

Questions were once again in abundance. Great answers were given by Alan, Professor, CPhill, Creeperface, Bertie, BluePhoenix912, Anonymous4338, and Rom. Thank you all.

Some nice recognition was also offered from BluePhoenix912, Bioschip and an anonymous person. Thank you we all appreciate it.

I used Kitty<3's 'fraction on the calculator' post 3 times this morning. It made answering so much easier. I usually have more than one forum page open at any one time so that I can post in one and refer to or copy from the others. I just copied the whole page - not just the address. It worked a treat. If anyone wants to use it is located in the sticky thread "Information pages worth keeping or developing."

Gib thinks all children should own a walrus. And s/he worked out how to insert a picture before Chris or I did. This is the post. I think Gib's walrus was the ugliest one in the pet shop!

We also have an anonymous comedian, s/he has visited before I hope s/he visits often. The comedian's post along with Chris's interaction was very entertaining! I thought it was great!! Although it would have been even better without the profanity. Thanks to both of you.

Alan gave me a much needed lesson on using the Tiny Pic upload feature. I made my first upload on the new system. I also added the address to the sticky thread "Information pages worth keeping or developing. Here is a direct link for anyone in need.

I think when Andre (the site owner and developer) finally gets the members section working properly we will be astonished at how many new members we have. It is great to see that a number of these are also answering questions. We encourage everyone to answer. Obviously if you are unsure you should state this, but ultimately it is up to the question asker to decide to accept or reject an answer. I also encourage people, especially the mathematicians, to check answers, including each others, so most mistakes are detected.

If new people would like to introduce themselves to the forum in general, by way of a public post, I encourage you to do so. If you would like to introduce yourself to me privately you can do so via the forum message service or by an email to the address that I will include at the end of this wrap. I love getting mail and I am sure other members would also welcome your contact.

We passed our 10,000th question today! BluePhoenix912 bought this to my attention with this post.

Thanks BluePhoenix, but you might like to edit your post, you left out a 0!

I had some really good thread addresses on my 'information pages worth keeping or developing' sticky thread. Now most don't work. They are full of old downloads. I wanted to use my 'dealing with negative indices thread' and could not. NOT GOOD! I suppose I'll redo them if I ever get time.

I can't recall any other memorable posts. If you can think of something or some post please let me know with a message. Then i can edit this wrap or include the omitted content tomorrow.

I am having intermittant problems with the \frac command in LaTex. Sometimes it works and sometimes it doesn't.

Gib took exception to my post yesterday and demanded an apology. It is here - I hang my head in shame.

A question that I personally would like take another look at was;

Here are some of the problems that we are experiencing;

1) There seems to be a problems with the picture inserts. Sometimes they are there and sometimes they disappear. I think they are related to the ones in Hogwart's.

2) Inappropriate, profanity posts were a major problem today. I have to write another letter to Andre this weekend and I will ask him if there is some software he can implement to make this less of a concern.

3) Some of the posts could not be opened - they just went off to 'page not found' eg "_^2,*2^_"

4) Our profile pages are still appearing on the 'Answer' page.

Great answers today from DavidQD, Admin, CPhill, Rom, Gib, Bertie and of course some anonymous people. Thank you all.

We noe have an outbox so we can see the messages that we have sent. That's a nice step forward. Other asspects of the members section still need a lot of work. Not to worry, it is comming together slowly. Our top answer board has changed again. The numbers have had another boost. lol Andre has told me that it has 'bug' so I don't know what it will look like tomorrow.

I did send a quick message to Andre. I told him of Alans's observations concerning the member profiles appearing in the answer section. I also asked him if he could run some kind of language scanner through posts so that some of the vulgar ones could be deleted automatically. He hasn't replied yet.

Great answers were today delivered by admin, BluePhoenix912, CPhill, Alan, Rom, Bertie, GoldenLeaf, reinout-g, Kitty3, bioschip, spetj200, some industrious anonymous people and definitly myself. Thank you every one.

Mathcalc also showed his appreciation. He always has great manners. Thank you mathcalc.

I encourage everyone to join in when reinout or I (or anyone else) posts a puzzle or a challenge. Thank you reinout, your efforts are much appreciated.

We have a great many new members joining every day and you are all extremely welcome. I love it when I see new people joining in and becoming known. It is not important whether you get an answer completely correct so long as your intentions are good and you state any uncertainty that you may have.

I am really pleased with how the forum is progressing. There are still quite a few bugs and some unfinished coding but it seems to me that almost every day some great new feature is introduced or an old feature has been improved. Thank you Andre. You are bringing it together nicely for us.

When we hover over a Math or LaTek input the coding now comes up in a box. This is great. Now we can learn how to use these by copying other people. Rom is our most competent LaTex coder. I started copying some of his more interesting code into the Latex page in the sticky notes. Unfortunately it disappeared and I'll have to do it again. My stupidity I think - not a forum error. If you add good coding when you answer a question please consider copying to the LaTex and Math Code thread. You can have your own post in there which you can add to as time progresses.

It has come to my attention that non-members can now upload pictures. This has pluses and minuses. Many of the posts that I deleted this morning were pictures. We have had very little of this type of problem in the past and it may be just a natural part of a growing forum. It is not a great cncern at present anyway.

My Wraps seem to be getting longer and longer. If anyone wants to comment on the content I will welcome your constructive comments. I want to know what people think!

It is midweek and the questions came in thick and fast. Some great answers were provided by GoldenLeaf,Foxtears, NothingLikeHmework, Rom, awesomeatmath, lebron, Alan, Bobtyford, CreeperCosmo, problem and reinout-g. Thank you everyone.

I think all the member questions have been answered. Not all answers have been checked and not all answerers have received the points to which I think they are entitled. I will put more effort into this tonight. Sorry. Sometimes there just is not enough hours in the day.

Many answerers put more effort into newer questions. This may be a little unfair but the logic is that if your question has been sitting there for a long time you may well have figured it out by some other means, so it may be less relevant. If your question has fallen off the first page you can repost if you want to. Remember, members will always get priority and it is simple and free to become a member.

Reinout-g updated our puzzle pages last night. Thankyou reinout-g. I noticed that CreeperCosmo has already answered 2 of the puzzles. This is great, I don't think that I have given you credit (and points) for them yet but I will.

I didn't do a wrap last night because access to the forum was denied to me. I was denied access for 24 hours there abouts.

Andre Massow, site owner and developer, has now found the cause and he sent me this message an hour or so ago.

"The problem is fixed. The reason for the error message was a programming mistake in my watchlist implementation. In your case the error appeared because you had a question in your watchlist which was delete later (by the question creator). The watchlist could not find the deleted question and crashed. "
Andre has temporarily deactivated this feature. I couldn't get the sticky topics to open either. Maybe he has deactivated these as well.

Thanks you Andre for finding and overcoming this problem for me.

There were also some nice shows of appreciation from some anonymous people as well as by Anana. we all thank you for this evidence of gratitude.

Also, Morgan Tud and Lady Guinevere both has something to say and Sisyphus showed us a holiday snap!

BIG NEWS TODAY.

CPhill is now a MODERATOR - He has the POWER OF THE TICK! CONGRATULATIONS CHRIS!

The WORD was out very quickly! This is a quote from Morgan Tud: (I will include the thread below.)

"Yea, Sir CPhill, whom His Majesty hath just Knighted, stood as a guard to the chambers of the Knights and did witness the circular pun and the leads to a circular paradox by Sir Cumference."

Hi everyone,

CPhill and I rather monopolised the answering today - sorry. There were a few physics ones left for Alan and admin answered one, thank you. Never mind the week should start getting busy tomorrow and then there should be enough questions for everyone. Also, every day I see many new names. The member section is not finished yet so I can't see you all but I expect forum member and post numbers is growing very quickly.

To all those who have joined recently, welcome to web2.0calc forum. We hope you find the site helpful, interesting and fun.

There were some really nice thank you notes and thumbs up given today by RheyB, bioschip, tyeiyei and an anonymous person. Thank you, everyone likes to be appreciated!

One of our members Daniavm reported an error via a post. I forwarded the post address to admin along with some of my own observations. Daniavm’s problem should now be fixed.

My observations were mainly to do with the Android phone app. I had learned to do most things. The member section could only be accessed by the most convoluted, intriguing process imaginable. I was really proud of myself for solving the puzzle. Anyway, there is no puzzle any more. Andre Massow (site owner and developer) has ‘fixed’ it, what a pity. So, from most people’s point of view the app works much better now. Thank you Andre.

This was an interesting physics question and answer (I thought so anyway). Alan has provided all the formulas. Someone else should plug the numbers in and give us a concluding statement. http://web2.0calc.com/questions/stuck-on-problem_1#r105221

Chris added a new problem for us to ponder, it is on a new thread but I have referenced the thread in Puzzles, which is a sticky topic.

http://web2.0calc.com/questions/tricky-puzzle-problem-from-cphill-can-you-work-it-out

An anonymous poster also added this one which was intended as a puzzle so I also referenced it on the Puzzles thread. It is a good one for school level scholars.

Today was extremely busy, Chris (CPhil) and I were answering questions for many hours. Many great answers were also forthcoming from Alan, BluePhoenix912, admin, zegroes, anonymous, cdromdj, GoldenLeaf, Creeperface and heureka. Thank you everyone.

I'd particularly like to thank Alan. Every evening Alan comes to the forum and answers a number of questions, including the physics questions that are beyond the other regular members' capabilities. I really appreciate this. On behalf of all members I extend a very big thank you to Alan.

Kato99 also offered a nice show of appreciation. Thanks for that.

Chris's first puzzle was solved by heureka and myself but Chris has changed the rules (Actually explained them better) so now the puzzle is really not solved. There is a second easier puzzle here as well.

I almost forgot to do the wrap! That doesn't happen often.

Lots of great answers today from reinout-g, heureka, zegroes, CPhill, Alan, winnie and SpawnofAngel. Thank you so much. I'd especially like to thank Chris (CPhill). Chris has been answering questions all day long. He does this regularly without complaint and I really appreciate it. There is not any appreciation expressed my most of the question askers, that is true, but there are a few who express their gratitude and they make a big difference to the moral of the answerers. Today 3 of these people were AngelAmy, zegroes and chilledz3non. We thank you very much.

Reinout-g has been looking after our brain teasers and puzzles. Notification of new ones are posted on the forum but they can always be found in with the sticky topics in the bottom right corner of the screen. There are some great puzzles in there - take a look. Thank you reinout for looking after the puzzles they are an important aspect of the forum! If other people would like to post puzzles you are free to do so. If they are good I will give them a green puzzle icon and reference them in one of the puzzle threads.

Reinout also worked out how the individual post are referenced. I might keep this till another time, there are a few more specifics that I want to work out. Again, thank you reinout.

Once again heureka has presented some great answers with very impressive LaTex. Thank you heureka!

I have been copying some of the Latex and some of the reference addresses over onto the LaTex thread which is located in the Sticky Topics. (Near the puzzles)

I guess we'll just have to cope the best we can, remembering always that members get priority. There were a smattering of very old posts appearing on the forum today.

Great answers were given by Heureka, CPhill, Alan, askar20106, reinout-g and Rom. Thank you all.

There were also som nice shows of appreciation from blaster0, RheyB, Jedithious and some anonymous people.

Our message centre has been redesigned from scratch. There are some features that are not properly implemented yet but some of the new ones will be really good.

We can now view our messages from oldest to newest or vice versa. Received messages and sent messages are now together in a converstion view (they are when you go into send message view anyway). Sent messages are left justified and received messages are right justified. Plus sent messages can be edited or deleted right up until they are read by the recipient. I used to love this feature (it was in the previous version of the forum) We cannot delete our messages at present but I am sure we will be able to soon. A message export system is now being developed and should be up and running in a week or two. The feature for choosing a member from a list definitely needs improvement but I think Andre Massow is repairing features and introducing new features in extremely good time. I commend him on his efforts and the results he has achieved! Thank you Andre!

There are a great many questions. Primary answerers are having a tough time getting through them all but we do do our best. I have always encouraged people to get involved and post answers were they are able. Unfortunately there are some people posting who do not have the knowledge base that they need to answer the question properly. These answers can be very misleading to the question asker which is definitely not good. They can also be time wasting for primary answerers. If you are one of these over-confident people who is posting answers outside your knowledge base please STOP! (I may start deleting point for wrong answers given by repeat offenders) If you lack confidence but you really believe you can help I do not want to discourage you. There have been some fantastic answers from casual answerers, today and everyday.

Here are just a couple of todays posts. I don't remember any really standing out.

I often knock myself trying to finalise everything before i write the wrap and then a number of people come in not long after and there is very little left for them.

Hi Everyone,

Today was a quiet Saturday/Sunday. It's nice to have a quiet day occasionally. Still there were some excellent answers given by Alan, reinout-g, CPhill and Bertie. Thank you.

I would like to introduce you to Rosala. Rosala has only been a member for a few days and she has already greatly impressed me. Rosala asks good questions, she is quick to say thank you, and gives 'thumbs up' generously on her own questions and also on other people's questions. She also answers questions well when she has the knowledge. Rosala is also very prepared to ask for clarification and to say when she does not understand. This is very important and something not many question askers really do. She may be a very important role model for others to follow!

Now that I have told you why Rosala has impressed me, I'd like to tell you a little about who she is. She is a 13 year old girl from Delhi, India. I don't know that we have any other regular members from India. She is very proud of her excellent Engish, it is her favourite subject. She said 'we' are lucky because we come from counties where girls can do anything. There are much less opportunities for girls in India.

Thank you Rosala and welcome to web2.0calc forum. I hope that you continue to learn lots and enjoy this site!

(Incidentally, I did ask Rosala if it would be alright before I repeated all this on the forum.)

Hi all,

It was a busy day today. All questions up to and including page 470, and all answers up to including page 1092 have been answered, checked, etc. This means there are still some about for people to answer and/or check.

Our great answers today were provided by Rosala, Alan, GoldenLeaf, mjohnson, admin, zegroes, zacpac2020, reinout-g, Heureka, Rom and TakahiroMaeda.

Mjohnson and Zacpac2020 both only joined up yesterday - could have been today since I am ahead of almost everyone else! Welcome to web2.0calc forum. We all hope that you enjoy yourselves here!

Now, there were lots of potentially interesting posts today and here are some of them.

Yesterday a few people told me how much they liked my 'End of Day Wraps' and how much they appreciated all the effort that I put into the forum. Thank you so much. I put more hours in here than many people put into a full time job. I do it because I love teaching and I really enjoy all the camaraderie of the forum but this certainly does not mean that I appreciate your gracious compliments any less. (Incidently, I think Chris (CPhill) spends as much time here as I do, his contibution is immeasurable.) It is a team of people who make this forum work so well. Without the team we could achieve nothing! Thank you everyone.

That is it for today, good evening/day all.

Yes, I know Zegroes - No one gave me a red carpet either - and I am still crying. See!

Actually the member section is not adequate to see the new members - it doesn't even bring up many of the old members! I think we have more than 10 new members every day, maybe a lot more. The only ones I catch are the new answerers. If someone answers a questions and I don't recognise their name then I look at their profile. If they are new then I welcome them. It is extremely hit and miss. When admin gets the member section working properly we need to organise something better. Maybe an automated welcome or maybe put someone in particular in charge of a welcoming committee.

Narsin and Sportslover have join since my last wrap. Zegroes and Rosala seemed to think they are also entitled to a formal welcome. So this is for all 4 of you. Welcome to web2.0calc forum. We hope that you learn lots and that you like it here.

I didn't notice a lot of particularly interesting threads this time, maybe I wasn't looking hard enough.

I thought that this one was interesting and important for a couple of different reasons.

Please take note of what Bertie and I have said. It is important that you are interactive with your learning. Answerers do not want to feel like they are just doing someone's homework and that the only thing that the asker cares about is the answer! We want to help people learn!

I am sorry notsomathpro. Our comments were not aimed at you in particular, I am sorry that you were the one in the firing line.

The question itself is also very thought provoking. I hope i get around to looking at this question from 'behind the scenes'

You know, I was only gone 1 night and you kids think you can just move into my wrap thread and make yourselves at home. And why is it that you are giving each other lots of points when my wraps never get any points. I should go on strike!

People have been asking where I was last night. I was at 'Vivid' which is an amazing light show in Sydney where moving picture lights are projected onto many of the buildings around our harbour. (I don't think that i said that very well)

It was a rainy day which meant that the crowd numbers were way down, for a while our luck held out and the weather was good. Then it teamed and we were drowned. The tadpoles in my pockets were the only really happy ones. Not to worry. It was all pretty amazing. The best displays were snakes slithering across our museum of contempory art, and schools of fish swimming across the opera house sails, followed by a shark and some stingrays. it was really cool!

Here are some pictures but they are never anywhere near as good as the real thing. Rosala in particular wanted me to explain. The scenes i described are not depicted here. It must be different each night.

Hi everyone,

Thank you Rosala, Zegroes and Reinout-g. I really appreciate your and everyones support. It means more to me than you will ever know. I also seemed to have ended up with quite a few 'wrap' points. Thank you so much.

Rosala wanted to know how the light were projected on the buidings that I was talking about last night. They were laser lights and they were projected from large boxes, maybe 2.5metres cubed, that were unobtrusively placed behind the onlookers. One of the very large buidings had a platform in front of its box and individuals were invited up to 'conduct' the lights. The lights changed quite dramatically depending on their movements. They could also play table tennis with laser light b***s etc. a bit like how you can interact using an xbox.

I really have to modify the way I care for this forum. I have spent many hours just checking everything is answered and collecting all the names. Once all the questions are answered to my satisfaction/capability collecting the names is easy enough, it is the answer checking and tidying that takes an enormous amount of time. I also collect threads for this wrap as I go. Does anyone have any suggestions on how I could do it differently or how someone else may be able to help?

There is a sticky thread called “Information worth keeping or Developing.”

I refer to it most days. It is full of addresses of threads that can be used over and over again.

It is not well organised and some of the older posts have info that will no longer display properly but it would be worthwhile for answerers to familiarise themselves with the newer posts. I write a little description above each reference address. You are encouraged to add your own post on the end. Once you have one post you can usually edit it to include new addresses. You do not need to make a new post every time.

Not much excitement today. Some one tried to abuse the site by posting 14 'assignment' questions but members soon ignored them, which seemed to be accepted as the correct response.

It came to my attention today that some people do not know how to copy and paste web addresses so I prepared this. The address is stored in the sticky thread called "information pages worth keeping or developing." Maybe one of you can do a better job. Mine is only good for windows operating systems. Actually I just this instant received a pop up from Zegroes. I think he was asking how to do it on a phone - but I could have got it wrong!

Great answers today from Alan, Rosala, CPhill, Zegroes, Bertie, Geele, Heureka, reinout-g, NinjaDevo, TreefAM, Scrutinizer, Problem, Sally1 and Kitty

Rhino also posted a great puzzle. It is a recurring one but a really good one. I have given it the green puzzle icon and added it to the sticky note 'Puzzles'. Thank you Rhino.

I almost forgot. Reinout-g has put a repetitive and recursive curse on CPhill. He can adjust the pain levels as he sees fit. Of course CPhill does deserve it. Headless and now cursed. Some knights are brave but not so smart!

In the last day or so there has been some rudeness aimed at answerers. Sometimes this is verbal other times it is in the guise of subtracting points even though the answer is not incorrect. I do not think this should be tolerated. It is my position that core members should back any answerer who has reason to feel s/he has been treated rudely. An apology should be sought and if it is not forthcoming future questions should be whitened out or not answered. The question asker has three basic choices:

1) Apologise (and return points) and it is over.

2) Leave the forum altogether.

3) Rebirth with a new username. (If they do this then it would usually be an indication that they know they have crossed a line and they are likely to behave better second time around)

I can not do these things alone. If you think this is a reasonable policy then I need your help to enforce it. Let me know what you think.

Great answers today from CPhill, reinout-g, Rosala, zegroes, Alan, Will85237, and Bertie.

Will85237 joined a couple of days ago. Welcome to Web2.0calc forum. We hope that you enjoy yourself here.

NinjaDevo made his way onto the "Top Answerers" board today. CONGRATULATION NINJADEVO. I had not realised that you had answered so many questions, (Ninja's are supposed to be stealthy) But, I have been very impressed with the quality of your answers Ninja. Thank you.

There have been a number of questions lately which are ambiguous or simply do not make sense. At Alan's suggestion I have posted a note question askers, requesting them to be careful about this and also giving hints to appropriate forum conduct. This is it.

Good Evening all, some of you live in slow places and the sun has not yet set, but I assure you, a good evening awaits.

It was a quiet day today. I am definitely not complaining! Bring on more days like this so that I can catch my breath!

There were still lots of good answers delivered by reinout-g, NinjaDevo, Will85237, Alan, Rosala, CPhill, Bertie and Bahamo. Thanks guys, you are all much appreciated.

Bahamo is new. Welcome to web2.0calc forum. We hope you learn a lot and enjoy yourself here.

I spent a little time this evening cleaning up Sticky Notes. They are a little improved but this area definitely need more time spent on it. Some of the content is from the old forum and does not display properly. Some content needs to be deleted or updated. I did 'unstick' a couple of obsolete posts and I amalgamated a couple more but there is still much to do. Andre was 'threatening' to reduce the number of sticky topics possible. I do not like this idea but he is right, they do need to be tended properly.

Yesterday I was asked to put together a note to new question askers requesting that they be very careful about the presentation of their questions. I did that, maybe it was in my wrap yesterday, I don't remember. Anyway, I was then asked if something like this could be permanently 'stuck' to the top of the posted questions. I do not have the power to do this but I think it should go into my next letter to Andre Massow (site owner and developer) Does everyone think that this is a good idea? Can anyone offer more input. Would someone other than me like to write it? I have put up a first draft (on the forum)but I also found an old similar post in the ignored sticky topics. In some ways the old one is better than the new. They need to be amalgamated and tidied up.

I have started a sticky note information thread for new people. (It is just a start)

http://web2.0calc.com/questions/information-for-new-people

I also want to remind people of the Sticky Topic "Information Pages worth Keeping and Developing". Once again this thread needs some loving care but I add to it regularly, and I use references from it even more regularly. I think it would be beneficial if answerers familiarise themselves with its content.

These are some of the interesting post from today.

What is the value of pi

I have added this one's address to the sticky topic "Information pages worth keeping or developing"

NinjaDevo · Answer 165 · 2014-06-14T12:51:51

I just looked at the sticky topic "Information pages worth keeping or developing," and I can agree that it could use some cleaning up.

A sugestion I have for this is maybe we should just have one huge post containing all this information, and the author (most likely you, Melody) could just "edit" the post when more information is wanted to be added.

Also, maybe a good way to organize this is by "grade levels" of mathematics, if you will. Looking something like this:

Algebra:

-link(s)

Geometry:

-link(s)

Triganometry:

-link(s)

Probability:

-link(s)

Misc. pages:

-link(s)

...and you get the idea

That way, when someone is refering back to the sticky about say, solving inequalities, they can just go under algebra, and go directly to that link, without looking through the whole page of reposts and stuff.

The only problem with this is that there might be a limit to how much text can go in a single forum post. If this problem arises, maybe the creator of the site could allow an option for a no-max charcter count for only mods when posting something.

Also, tell the creator of the site (Andrew, I believe?) that I appriciate his work on the site, it's really made well.

Finally, thanks to your dedication to this site, Melody, without your and dedication, the site would not run as it is running!

I would also like to echo ND's thoughts....thanks to Melody for all she does on here.....

I'm still getting "phantom messages," as well.......maybe they're from a "ghost" poster.....!!! Who knows ???

I like ND's idea about classifying the posts according to grade level or topic......I don't know if the site mods would be responsible for "moving" the topics to appropriate areas (yuck, another "task"), or whether the site could include a "menu" for the questioners in which they could choose to post where they thought most appropriate. (Maybe we could include a "miscellaneous" category if a questioner were uncertain!!).

Those are my thoughts......but, I might have more as they occur to me !!!

It occured to me today that one of the things I always wanted for this forum was a 'club like' atmosphere. I was thinking that with the ability to post without becoming a member first that this may never happen. However, I am really pleased because I think that the forum may be headed that way now. We have a number of core users of all different ages and abilities. You are all lovely people. I have a great deal of time for each and every one of you. You are starting to communicate with each other on the forum in a very constructive and friendly way. I am really pleased that the forum is starting in this direction!

This forum is very young. I compare it to a young river gouging its way through mountains and valleys. It is intriguing to watch it grow and mature.

I greatly appreciate your show of interest in my evening wraps. It used to be quite lonely in here because i wasn't really sure if anyone was actually reading what I wrote. However, I would like it if you would show your appreciation for my wraps in the lantern thread that I put out each night after I write the wrap. Do you know where I mean? This 'wrap' thread should just be for the wrap and for posts that are directly related. For instance Ninja wrote a post saying that he had done what I had requested. Or, when I missed one night I didn't mind Zegroes commenting that there was something missing. I want all the posts in here to be constructive and directly relevant.

Welcome to web2.0calc forum jboy314. We hope you continue to write great answers. We also hope that you have fun and learn lots.

As many of you know, NinjaDevo has made an improved version of our Sticky Thread "Information Pages worth Keeping or Developing" The presentation looks fabulous. Ninja says he has included (almost) all the information that was in the old one. I have been intending to check it out properly but I can see the only way that is going to happen is if I put it up properly for people to use. Ninja has included the address of the old version on the first page so if anything is missing it can still be easily found. I used the old version of this thread quite heavily. I don't know if other people did or not. I really encourage you to see what is there and to make full use of it. If you want to add your own information/comment page that is encouraged (you only need one, you can edit it if you want to add things) Please respect the fact that it is a serious thread and treat it with respect.

It seems that US schools are on holidays and the children are misguided enough to think that they have better places to be than our forum. How misinformed they be. Still, there are always good questions and excellent answers follow in their wake. The answers this weekend haave been delivered by NinjaDeva, CPhill, jboy314, Heureka, Reinout-g, Rosala, Zegroes, Alan, Rom, DavidQD and MorganTud. Thank you. You are all wonderful. ♬

Ninja has posted a new version of "Information Pages worth Keeping or Developing" It can be found in the Sticky Notes. Please familiarise yourself with the threads within, some of them are excellent. I have not used the new thread much yet but the setting out is visually very appealing and i think that NinjaDevo has done a really good job. Thank you NinjaDevo. If you would like resources to be added Ninja has asked that you message your requests to him and he will see that it happens. However if you prefer, you may add a post of your own and add resources there. Please only add one post. You can then edit it or add to it as you please.

Rosala has learned how to use memes and her squirrels are cute. I also like the fact that although Rosala and Zegroes have had some fun they have not given yourselves points for it. Generally speaking I think points should mainly be kept for proper mathematics posts and just a few for the very best of the fun posts.

Whenever possible answers AND questions should be checked to make sure that they pass reasonableness checks. Thank you Alan for reminding us of this.

3 different method to exand double bracket problems. I like Alan's method best. If I were teaching it in a class I would give a preamble on finding areas first and make sure the students could see the 'link'.

Hi everyone, is this a ghost town or what? I am actually enjoying brake. But is the entire forum made up of US school children? I know the core group is not, but maybe the rest are. They certainly all seem to be on holidays. I hope that they are having lots of healthy fun!

Still, there were a few good questions and these were answered by Rosala, CPhill, NinjaDevo, Rom, Alan, Reinout-g, Heureka, Bertie, and Kitty. Thank you all.

Communications with Andre Massow. (Site Owner and Developer)

On the 16^th June I sent an email that listed a number of items that I asked Andre to consider, improve, or implement. Today I received a response:

# There was an error in the message centre. The inbox items were displaying properly but the outbox was displaying the incoming messages not the outgoing ones. Anyway, Andre has now fixed this problem.

# Andre has introduced a reply button on incoming messages. I have already used this, it works well.

# Messages can now be viewed from oldest to newest or newest to oldest.

# Andre has introduced an Export Button. There is a “save disk” icon at the top of each conversation. It exports in Microsoft Excel file format. I have used this, it definitely works. It appears to export so that the newest message is on the top no matter which way around the messages are displayed. The layout appears to be a little confusing if the messages are long. I’m sure that I will work it out quickly enough.

# Andre has introduced a new “To” input field in the compose message section. Before, there was just a drop down box but now you have to input something. If you input “tr” all the usernames containing “tr” anywhere in them are brought up. I entered R and no username that actually began with R was bought up – Maybe only the first 25 possibilities appear. I don’t know. It is a bit of a mystery at the moment.

# There are a few other issues that Andre is still considering.

# I just discovered that if you go into any person’s profile, there is a new button underneath the avatar. It says “All Profiles”, if you click into here you will find a comprehensive list of members. It is in alphabetical order and it gives joining date as well as number of questions asked and answered. I asked Andre for something like this but he did say that he had done it in his letter. So finding this was a nice surprise.

Once again, on behalf of all forum members, I would like to extend a very big thank you to Andre for all that he is doing to improve our forum.

23/6/14 Included in the wrap.
