@@ End of Day Wrap - Thursday 19/6/14   Sydney, Australia   Time 10:10pm 

Hello everyone,

Lots of great answers were provided today by Zegroes, Rosala, reinout-g, Anonymous4338, Pokemonfan58, Alan, CPhill, Bertie, Heureka, Strider, NonjaDevo, MathWizard and Kitty<3. Thank you all.  

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.

Please don't take this as discouragement.  I really like your friendly posts but please put them on the lantern thread. 

Here are some interest posts for the day.

Ah, M'lady doth not appreciate the craft and skill of one so humble as myself ???..........Sisyphus himself was so over-awed by such display of number manipulation that even he took  brief reprise from his unending duties to pay homage to CPhill  !!!

Now.......back to work, Sisyphus    ....    !!!

CPhill

thank you reinout.

A picture with words written over it is called a meme.

There are several pictures with a standard meaning such as

first world problems

anti joke chicken

succes kid

there are many, many more but it is also common to use other pictures with the same thing.

There are several websites where people post millions of these every day. 

People vote them up or down and the most popular ones appear on a 'popular' page.

If you want to make one yourself you can use;

what a show off Chris,  

okay reinout,

you are looking for something to do.  We need a new number puzzle. ta.  

okay here is one.  What program are you using to write over pictures like that?

Yes Chris, there should always be time for siliness.  I've given you a couple of thumbs up for you 'fun' efforts. 

mmm what more can i say.  

Pretty busy....but there's ALWAYS time for some foolishness, too !!!

Doesn't this forum keep you busy enough Chris? lol.

heureka has shown the method known as "completing the square"...we can also use the "quadratic formula"

It's given by  

[-b ± √(b^2 - 4ac)] / (2a)     where, in our case..... a= 3   b = 4    and c = -2   so we have....

[ -4 ± √(4^2 - 4(3)(-2))] / (2*3)  =

[ -4 ± √(16 + 24)] / (6) =

[ -4 ± √(40)] / (6) =

[ -4 ± 2√(10)] / (6)      (divide everything by 2)   =

[ -2 ± √(10)] / (3)

Note that this is exactly the same answer(s) as heureka's  !!!!

is there a simpler way? thanks.

Generally, variables can be stored for about two weeks with proper refrigeration. To prepare for storage, wash the variable first with mild soap and water, making sure to rinse, afterwards. Then, carefully place the variable in a plastic bag to prevent freezer burn. Variables keep best at about -4C  - you Fahrenheit prople can work this out for yourselves.

After two weeks, the variable is only fit for random puposes  and should be disposed of accordingly.

Hi Alan and Strider,

Alan, I am glad you understood what Strider was talking about because I had no idea.

I'm sorry but I don't know what you mean.

hi Dragon,

The dot just means multiply

$$a(a-8)-2(a-8)\\\\
=a^2-8a-2a--16\\\\
=a^2-10a+16\\\\$$

I think Cynee may mean how do you fill in a table of values.

Have a look at this Cyndee.   

5.09 x 10^-8 / 0.04 x 10^-8

Firstly I assume that you mean - people really must learn to use brackets!  (not aimed just at you)

(5.09 x 10^-8) / (0.04 x 10^-8) 

the 10^-8 s cancel out leaving

5.09/0.04=

$${\frac{{\mathtt{5.09}}}{{\mathtt{0.04}}}} = {\frac{{\mathtt{509}}}{{\mathtt{4}}}} = {\mathtt{127.25}}$$

Indeed he could!

Aah, I guess if someone's interested (s)he could try and see where the fault lies in these.

Well thought of Melody 

I have just added this address to the sticky topic "Puzzles"

This is not really a puzzle but it is in that vein.
