It won't work in here at the moment because some of the packages are missing.
Another thing to talk to Andre about - this is often a problems.

I tried the code below but it didn't work 
HEUREKA HAS SHOWN ME HOW TO DO IT (14/10/14)
\sum \limits_{n=1}^{\infty} : $$\sum \limits_{n=1}^{\infty}$$
----------------------------------------------------------------------------------------------------
\displaystyle \lim_{x\rightarrow -1}\;\;\dfrac{|x+1|}{x^2+1}
$$\displaystyle \lim_{x\rightarrow -1}\;\;\dfrac{|x+1|}{x^2+1}$$

More ideas from LancelotLink
\ V(x)=\dfrac{W}{m}\ = \dfrac{1}{m}\int \limits_{\infty}^{x}\ F\ dx =\dfrac{1}{m}\int \limits_{\infty}^{x}\dfrac{GmM}{x^2}dx=-\dfrac{GM}{x}
$$\ V(x)=\dfrac{W}{m}\ = \dfrac{1}{m}\int \limits_{\infty}^{x}\ F\ dx =\dfrac{1}{m}\int \limits_{\infty}^{x}\dfrac{GmM}{x^2}dx=-\dfrac{GM}{x}$$

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!
