In answer to all those people who want to know how to do fractions on this calculator:

Here are some of the replies from various answers; I hope they can help you out:

Re: How do you do fractions on this calculator?

"5 and a half - 8 and a quarter would be

$$\left({\mathtt{5}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{2}}}}\right){\mathtt{\,-\,}}\left({\mathtt{8}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{4}}}}\right) = -{\mathtt{2.75}}$$ "(by Melody)

Re: where is the fraction button

"It is a box above a box" (by Anonymous)

"On many calculators out guest is correct. There is no fraction button on the Web2.0calc You have to use the $$\div$$ button. To enter 3 and 1/2 - 6 and a quarter you would press

$$(3+1\div2)-(6+1\div 4)=$$" (by Melody)

Re: How do we use fractions on this calculator??

"with the $$\div$$ button. If you are doing calculations with mixed numerals it is best to put them in brackets like $$(3+1\div 2)$$" (by Melody)

"You can use forward slash / as we write in a fraction. 6/2 is a fraction. And if there are more numerals involved, use brackets as (6*2+8)/4

I hope it helps." (by novice)

"you simply make it a decmil if 4 were 1/4 i would put 4.25" (by Gman2598)

Thanks to everyone who answered!

The calculator has a built in database for a large number of constant values used in for example physics.

Think of things like the atomic mass constant or electron mass.

You can acces it by choosing [snd] [const] where you'll find a list.

[size=150]__ Fun with Fractals__[/size]

I've been of looking at some interesting you tube clips on Fractals.

I thought some of you might like to watch one too.

http://www.youtube.com/watch?v=XwWyTts06tU

Just highlight the address, right click and choose goto.

There are some other videos there too. I haven't looked at the others but they look like they would be interesting too.

Actually when I think about it, almost all the time I do refer to a website, it is some part of www.mathisfun.com.

The website explains lots of things in mathematics from percentages to pythagoras theorem.

I like the website a lot because the explanation generally does not require any pre-knowledge.

The website explains in a very clear (and yet not dry) way why something is used and how someone can use it him/herself.
