This article explains how to use LaTeX in the AoPSWiki, the AoPS Community, and the AoPS Classroom.

LaTeX on the AoPSWiki and the AoPS Community

LaTeX uses a special math mode to display mathematics. To place something written in TeX in math mode, use $ signs to enclose the math you want to display. For example, suppose you type the following in a Community post or in the AoPSWiki:

The solution to $\sqrt{x} = 5$ is $x=25$.

The resulting post will read:

The solution to is .

As we saw above, when using $math stuff here$ to typeset math, the resulting math expression appears right in the text at the location of the $...$. Sometimes we want to break some of the math out of the text and give it its own special line. To do so, we use \[math stuff here\] or $$math stuff here$$ to put the math text in display math mode:

The solution to \[\sqrt{x} = 5\] is \[x=25.\]

The output of this is:

The solution to is
