Thanks

    $\begingroup$ Oh, I expected this question to be literally 'How to read and write mathematics?" :-( $\endgroup$ – Robert Smith Nov 3 '10 at 18:00
  • $\begingroup$ @Robert. Me too and I had the answer: "From left to right". :-) $\endgroup$ – Agustí Roig Nov 3 '10 at 18:07

    $\begingroup$ @Agusti: not necessarily true. $\endgroup$ – Willie Wong Nov 3 '10 at 19:06

  • $\begingroup$ @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". $\endgroup$ – 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 $\LaTeX$.

    $\begingroup$ I think you meant to type \LaTeX ($\LaTeX$) and not \Latex ($\Latex$). $\endgroup$ – Rahul Nov 4 '10 at 2:19
  • $\begingroup$ Yes, the camel caps matter (also with \TeX). $\endgroup$ – J. M. is a poor mathematician Nov 4 '10 at 3:51
  • $\begingroup$ Thanks! Those caps are Important! $\endgroup$ – Matt Groff Nov 6 '10 at 13:47
  • $\begingroup$ how bout $\LaTeXe$? $\endgroup$ – 97832123 Nov 7 '10 at 1:31
  • $\begingroup$ @978: Perhaps \LaTeX2e ($\LaTeX2e$). Edit: Huh, that's not the $2_{\textstyle\varepsilon}$ logo I'm familiar with. $\endgroup$ – Rahul Nov 7 '10 at 4:43
  • $\begingroup$ @Rahul: Oui, précisément. $\endgroup$ – 97832123 Nov 7 '10 at 7:27
