'''LaTeX''' is a typesetting language used primarily to type mathematical expressions in an elegant fashion. For example, without LaTeX, <math>\frac{35}{137}</math> would have to be written as 35/137.  To use LaTeX in the forums, enclose your LaTeX code with dollar signs: <nowiki>$your codes here$</nowiki>.  To use LaTeX on AoPSWiki, you can enclose the code with dollar signs as in the forum, or you can also enclose your code with math tags, like so: <nowiki><math>your codes here</math></nowiki>.

Note that on AoPSWiki, many codes that work on the AoPS forums do not work.  Also, a helpful tip is that if LaTeX fails to render within AoPSWiki, try adding the code \displaystyle to the beginning of the string of LaTeX.  This often fixes minor rendering problems.
 
 
 
 
 
Also note that you do not have to use braces, "{" and "}", when you only want one character in the operation.

The $\text{\LaTeX}$ typesetting system (typically pronounced "lay-tex", but also sometimes "lay-tek", "lah-tek", or "lah-tex") is widely used to produce well-formatted mathematical and scientific writing. $\text{\LaTeX}$ is very handy for writing equations such as

\[\sqrt[3]{4^2+\frac{5}{3}+\pi} \approx 2.75\].

Nearly every serious student of maths or science will use $\text{\LaTeX}$ frequently. Through these websites, you will learn what you'll need to express maths and science like a professional, much, much better than Microsoft Word!
