# How to read and write mathematics ?

A very basic question:

How to type mathematics correctly in this website? I am a new member.

Thanks

• Oh, I expected this question to be literally 'How to read and write mathematics?" :-( – Robert Smith Nov 3 '10 at 18:00
• @Robert. Me too and I had the answer: "From left to right". :-) – Agustí Roig Nov 3 '10 at 18:07
• @Agusti: not necessarily true. – Willie Wong Nov 3 '10 at 19:06
• @Willie Wong: And we should not forget all Arabic journals :) – AD. Nov 3 '10 at 19:45
• @Willie and AD. :-DD @Yuan. More seriously: look at some questions an answers. Particularly, when there is a link on the right side of "edited", at the end. Click on it. Then click on "view source". This lingo is called "LaTeX". – Agustí Roig Nov 3 '10 at 22:20

TO briefly expand on Agusti's answer, $\LaTeX$ is used to represent math. You simply put the symbol $in front of and after the math. You can see the$\LaTeX$crash course here. Just use dollar signs instead of their [tex] and [\tex] symbols. You can practice in their forums if you like. They have a button where you can preview$\LaTeX$. • I think you meant to type \LaTeX ($\LaTeX$) and not \Latex ($\Latex$). – Rahul Nov 4 '10 at 2:19 • Yes, the camel caps matter (also with \TeX). – J. M. is a poor mathematician Nov 4 '10 at 3:51 • Thanks! Those caps are Important! – Matt Groff Nov 6 '10 at 13:47 • how bout$\LaTeXe$? – 97832123 Nov 7 '10 at 1:31 • @978: Perhaps \LaTeX2e ($\LaTeX2e$). Edit: Huh, that's not the$2_{\textstyle\varepsilon}\$ logo I'm familiar with. – Rahul Nov 7 '10 at 4:43
