The end of the day wrap was introduced by Melody way back in 2014
Here are the original links:

ADDRESS OF WRAP #4:
Though they are discontinued, I had great fun reading them yesterday night. That is when I got the idea...to start “Wrap 5”.
At first, I did not think I could do it, (as my account was relatively new, though I had been watching behind the scenes for quite a while), so I privately asked Melody if she wanted to do it, or if she did not want to, I could start it for her. She told me that I could do it for her.
With Melody’s permission, I decided to start Wrap 5. It will never be better than Melody’s original wraps, but we shall see the outcome!
This wrap will be stickied at the “Stickied Topics” section. I will post as often as I can (hopefully everyday), so please check it out whenever you can.
Following the previous tradition, there will also be a “Lantern Thread”, but instead of it’s original purpose (which will be incorporated), it will also remind people to check out the Wrap 5, because trust me, I just finished writing the first post (on a google doc), and it is a WHOLE lot of work. (Congrats Melody for doing that for almost two years!)
Oh right, you probably don’t know me, because I’m not as famous as Melody. Let me quickly introduce myself.
My username is ilorty, and I actually have no idea how I found this site….
I was born on Earth, which is in the Solar System, which is in the Milky Way Galaxy, which is in what humans call the Universe.
(You really should visit Earth, such a lovely place, despite having the highest crime rate in the galaxy, lol)
Before going to the posts, I would like to enforce some “Wrap rules”:
1. If you want to reply to the thread, do not start a new answer. You can private message me.
2. If you do reply (AKA private message or on the Lantern Thread, which will be created the day after the wrap is posted (only one lantern thread per week)), please make it appropriate. Don’t spam anything. Here are a list of things you could reply:
- If you have someone to shoutout (for an amazing answer)
- If you want me to include something in the next posts
- If you would like to post your thoughts on the post
- If I made a grammatical/mathematical/spelling error in one of my posts
That being said, I will post posts as a reply to this post. (so many posts…)
Finally, I would like to acknowledge Melody, the moderator that started the Wrap.
Have a nice time reading the Wrap….oh and don’t forget to eat one while you are at it :)
P.S. Once this post is locked, and I did not notice it, or did not contact a moderator to unlock it, feel free to tell one yourself, but include the link of the wrap.
September 2, 2020:
Happy September, lovely people of the forum! I can't believe August is over! This is the first wrap post. Before going on, please read the introduction. (original post) It will set some guidelines, and tell you what the heck I am doing, and who I even am.
Before going on, I would like to recognize this answer created today:
It was by Omi67, a moderator that usually hangs out on the german forum, and sometimes on the english one. (well, most of the time...the german forum seems to be way quieter than this one)
Please go head over to the question, read the answer, and give them a like.
Here we go:
There have been a few bugs lately. You can’t edit your post once you preview, you can’t give a like, and so on.
I found a way to give someone a like, even though the system does not allow that.
There are two ways to do it:
Enter that person’s profile.
Go into that person’s profile, find the answer that they created, and give the like! (don’t go into the answer, stay in the profile)
Go to the answer tab
Go into the answer tab, find the answer that they created, and give them a like! (don’t go into the answer, stay in the answer tab)
A lot of people have been wondering where CPhill is. Whether that is on the leaderboard, or for stalking purposes. (If the latter, please stop immediately, because I’m not letting you into my home sweet home)
He has been taking a break for the Summer, maybe to find Roman Numeral 0! (it has been a while since he aborted that mission. Maybe someone will convince him to go back to searching)
For people who want to know where he is on the leaderboard, press the “down arrow”. Then his name will appear at the top. (Sorry Melody...he’s still there!)
Recently, (mostly guests) people have been taking a lot of pictures of their problems. But, it is a pain to answer them….. BECAUSE THE PICTURE RESOLUTION IS OVERWHELMINGLY BIG!!!! (sorry, got a little excited)
So please, adjust the image size. You can use this site: https://resizeimage.net/ (i have not tried it yet)
If one of your dimensions is over 700, then let me tell yea, it’s way too big. The best size is probably a max of 500.
Unanswered Problem of the Day:
There have been a lot of unanswered problems, mostly by guests, that have not been reposted yet…
So I will feature a very “interesting” problem I found:
It isn’t too hard, so I will give you guys the chance to try it.
Math comic of the day:
created by xkcd, you can check their work out
And….this concludes out wrap. (hope i did not disappoint you, melody :P )
Comment here on the Latern Thread, but DO NOT comment on this thread
September 3, 2020:
Good evening! (or whatever time of day it is, good night just did not sound appropriate)
I try to post at 12 AM (midnight) GMT (8 PM where I am from), but not always on the dot.
Thank you EP for creating the most answers!
There was this really interesting question: https://web2.0calc.com/questions/please-help_89463 about camels and caravans, a really rare topic to talk about that ElectricPavlov answered.
I found these old posts that have not received any answers. You can reply to the post, but they will lock automatically once you post, so you can reply to my Lantern Thread. Here are the questions:
“find the slope 4x-5y=20”
These are the easier questions, and they are quite old.
So far, there have been 3 unanswered questions. Here are the links (for today)
https://web2.0calc.com/questions/it-s-urgent ←----- fine, it’s answered, but it has a troll answer
https://web2.0calc.com/questions/it-s-urgent-guys-pls-fast ←-------- yet another troll answer
If there are any more unanswered questions that I have not covered, you can add it to the Lantern Thread. There are some that I purposely left out due to bad formatting, not solvable unless you can use the website, or it leaks personal information. (there have been a lot of screenshots that give a way google meet IDs, full names, gmails, etc. )
Many people can’t post their LaTeX correctly (due to a bug). So, if you desperately need LaTeX for your answer\question, you can use https://quicklatex.com/ and take a screenshot and upload it. Speaking of which, I will include a detailed step by step on how to upload a picture on the Safari\Chrome browser, since the system blocks picture uploading to some websites.
(you will find the guide in tomorrow's wrap, as I am still creating it)
There has been this guest troll who has been posting believable answers that are completely random. (here is one example of their one-liners (this is one of the less believable ones, but there are others that seem believable)):
“|a + b + c| = 7/3.”
Found here: https://web2.0calc.com/questions/it-s-urgent ←----- for those who have time, please take a look at this post, and try to hep dp answer it (but, dp, from now on, you can use my method to post LaTeX questions. If your LaTeX is not proper, then the question is highly unlikely to get answered.)
So, for answerers, if you see a post that has one reply, you should visit that post to see whether it was a troll reply or proper reply. Usually ticked questions don’t include troll answers.
To the askers, please don’t repost the moment you see a troll answer. Wait. Your question will get answered, if it is not too hard. If it has not been answered after a day, then I will include it in the “unanswered questions” section.
To the guest, please stop. Melody has already told you to stop a year ago...and here you are again.
Fields Arranged by Purity:
What about philosophers?
That concludes this wrap. You can post your unanswered questions, thoughts, and comments in the Lantern Thread over here: https://web2.0calc.com/questions/lantern-thread-september-2-9
(Yes, you will see that we have been ‘talking’ about aloud and allowed)
Sorry I'd there is any issues with this post. I am currently multitasking, and busy, so I did not check it over. But I will once I finish my work.
September 4, 2020:
To all those who had suffered the tragedy of my wrong links: I have corrected them! And, I would like to say why those led to nowhere. Many people who HAVE included links have had them lead to nowhere, even though the link address is right...this problem will be covered later.
First, I would like to thank these members for answering questions with real proper answers (that were not copied, or don’t have an explanation, and were not based off of guess and checking) today (the order does not mean anything):
And...those are all the answerers that answered after 8PM GMT. If I missed you, I am terribly sorry. I made sure to check the answer tab, so your name might have not been on there because the answer was not “proper”.
How to make a link that does not lead to 404 Page Not Found:
There have been a lot of links recently that have led to 404 Page Not Found, including some of mine.
The links are correct, it is just that there is a space ( ) after the link. The program cannot detect if that space is part of the link or not, so it will just assume that that space is a character, which changes the link.
Make sure that you do not add any extra “spaces” after the link to ensure that it leads to the right place.
Most of the bugs have been fixed, including the LaTeX bug that did not render LaTeX. For members, this is now fixed, but when I logged on as a guest just to check if LaTeX worked, it did not render. (or it may just be me)
The "giving likes" bug is also fixed, so give as many likes to your answerers as you want!
There is still another bug that I will elaborate on in the “Bugs” section.
There is this one bug that happens when you post multiple times in a row. Sometimes you are able to post multiple times in a row without this picture showing up:
(This picture was taken by gwen)
I have addressed this problem here:https://web2.0calc.com/questions/glitch-on-site-or-is-it-only-me
If you are facing the issue, you can head over to that link.
How to upload a picture for Safari/Chrome users:
I promised to make a guide for uploading pictures on today’s wrap, and so I did. There have been lot’s of guides, but none of them work on Safari or Google Chrome, so I will tell you how I get my pictures.
1. Go to imgur.com
2. Press “New Post”
3. Press “Choose Photo or Video”
4. Select the photo you want
5. Once the photo is successfully uploaded, use a mouse and LEFT CLICK the image (for mobile devices, long click the image)
6. Select “Open image in new tab”
7. Go to the new tab, and copy the link
8. Head over to web2.0calc.com and create your post
9. Press the “image” button and paste the link you copied
Voila! Your image should be ready. Remember to RESIZE it, just to make sure that it is not too big. (go to first wrap to see how to resize)
I’m sorry I was not able to upload the images. The file was too big to download...but hopefully the instructions are easy to follow.
That is it for tonight!

September 5, 2020:
I can’t believe it is already the 5th!
I would like to introduce to you a pet of mine, the headlesschicken.
He follows me around, and if I ever get annoyed at a user, he is the account I will use to calm myself down. So, if you ever find him anywhere, (he is always getting lost), stay calm, even though he might be an ugly sight.
Anyways, here are the members that have answered with proper answers:
You might have noticed, I have never put my name in there, whether I answered or not. It would be weird if I did though...and not so modest. headlesschicken reminded me that modesty is very important, so he erased my name off the answerers list.
How to submit an answer:
Okay, everybody should know how to submit an answer...right?
Yes, that is true, but some answers are a pain to look at! (okay, maybe not a pain, but it could be better ;P )
Let me ask you a question. Would you rather look at an answer that is like this:
We know that x is = to y so we can say that 2x = 2y. From here, we also see that x > 78 and y is less than 80. This will tell us that 2x is equal to 2y is useless, and therefore we must not use it for any case. After some math we see that the only integer solution is x and y = 79 because that is what the inequalities tell us. And that is the end of my answer hope it helps u please give like and have a nice day.
Or would you like to see an answer like this:
To begin this question, we see that x is equal to y.
x = y
To find the integer value of x and y, we need some guidelines. Using the information that we know, we can say:
x > 78
y < 80
In other words:
78 < x, y < 80
This means that we need to find the number that is between 78 and 80. We see that there is only one number, and that is 79. Therefore, x and y are equal to 79.
Obviously, we would like the second one much better, right? I know that it takes WAY longer to write that, but trust me, you don’t need to lift your bottom off that couch or change out of those pjs that you have been wearing for three days in a row.
So starting from now, each wrap (maybe not forever) will have a writing tip for you to better structure your answer.
Here is today’s tip: Give your equations their own line. It makes it SO much easier to read, and it looks much more organized.
Problem of the day:
Though this is a math forum, there have not been questions that make you go: AHA! I know what to do now!
So, to sharpen everyone’s “logic” skills, I have brought to you a question for you to solve.
2014 AIME Problem 8
The positive integers N and N2 both end in the same sequence of four digits abcd when written in base 10, where digit a is not zero. Find the three-digit number abc.
This problem CAN be done with guess and checking, BUT, there is a mathematical way to do it, because the answer is actually quite BIG. DO NOT POST THE ANSWER AS A REPLY TO THIS THREAD.
There have been quite a few bugs lately, some that you might have noticed, some that might have slipped through.
There was one bug that was fixed very recently. Before, you could not press the down arrow on the leaderboard or the watchlist unless you were on the main page. Now, you can!
And….that wraps up the wrap!
September 6, 2020:
Happy Sunday everybody! (or whatever day of the week it is…)
Before we start, there was this really (and I do mean really) interesting question that caught my eye: https://web2.0calc.com/questions/please-help_95143
I checked it out...and guess what? I could not find an answer!
I’m not sure whether it was me that understood the problem wrong or not. There was a guest that already answered the question, but I’m not sure if their interpretation is right or not…
Anyways, I would like to congratulate all the answerers that contributed today:
I have not had as much enthusiasm and motivation to answer as last week...who knows why? Maybe because I aged a year...but I hope to find that motivation sometime soon…
There is not much news for today, except for something Melody has noticed.
She told me that the forum was much “livelier” (if that is the correct word) in the past than it is now.
Back then, each post would turn into something to joke about (that actually is true, I read some old posts, and WOW, boy were they much “livelier” than today’s).
The newer members are very intelligent, and are learning a lot, but the “liveliness” has gone down a bit.
Since she (Melody) has been such an important role in the forum, I think there is a way to make this forum a bit “livelier” (boy have I used that word A LOT).
And that is….A CONTINUED FORUM THREAD THINGY.
I know. Even I have no idea what I am talking about. But, I was thinking, that maybe because of all that couch potatoing that we have been doing for the past….who knows how long….we have lost our motivation and excitement.
So, I will be starting a “continued forum thread thingy” tomorrow. Everyone can participate, and yes, it is math related.
So here is how it works. The topic is “2012” math competitions (because that is when the calculator was created). You can search up an archive of 2012 math competitions, from AMCs to AIMEs to MathCounts.
I will start with a question. Then someone answers and posts a new question. Then someone answers that question and posts a new question...and so on. So that is one thing to look forward to tomorrow.
The next four days are going to be busy, as there will be many math competitions, continued forum thingies, and much more. Here is what I hope the schedule would look like:
Monday: 2012 Math Competition continued thread thingy
Tuesday: Answer Competition (as tuesday is international literacy day. More will be explained in tomorrow’s post)
Wednesday: Sudoku Competition (Wednesday is international sudoku day)
Thursday: Remainder Game (more would be explained on wednesday’s wrap)
Beware of the pronouns. Don’t use the word, “it” too much, as some people might not know what “it” defines. Let me give you an example of an imaginary answer that uses “it” too much:
Is it a fraction or not? 3x + 4 = 12 is what we want to solve. It has two terms, 3x and 4. It equals to 12. We subtract 4 from it and that is 8. We divide it by 3, and we get it’s answer, which is 8/3. So we know that it is a fraction.
Though this question is relatively easy, you still can follow along. But, we see that the word “it” has been used to describe 5 different things. We also never told what “it” is. Based on “it has two terms”, we might think that “it” describes the left side of the equation, but that is after a long period of thought. But then, “it” is used to describe 12, and then “it” is used to describe 8.
That is it for tonight!
Stay tuned for the next four days, as it would be filled with lots of “math fun”. It would be weird if nobody joined…
