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

Useful Codes

\boxed{Answer} Produces a box around your Answer.

\frac{a}{b} Produces a common fraction with numerator a and denominator b.

^\circ Produces the degrees symbol.

\text{Your Text Here} Produces text within LaTeX.

\sqrt{x} Produces the square root of x.

a\equiv b \bmod{c} Produces a is equivalent to b, mod c.

{9\choose 3} Produces 9 choose 3.

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.

  • \normalsize (10 pt.)
  • \large (12 pt.)
  • \Large (14 pt.)
  • \LARGE (18 pt.)
  • \huge (20 pt.)
  • \Huge (24 pt.)

Font styles
