'''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: <math>your codes here</math>.  To use LaTeX on AoPSWiki, enclose your code with math tags instead of dollar signs, like so: <nowiki><math>your codes here</math></nowiki>

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

\[1+2+3+4+5+\sin \pi = \frac{5\cdot 6}{2}+0=15.\]

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