Formulae
All Wikia are able to use the MediaWiki math extension to add mathematical formulae to articles.

MediaWiki uses TeX markup for mathematical formulae. TEX, or TeX, is a typesetting system which has largely displaced Unix troff, the other favored formatter, in many Unix installations. TeX generates either PNG images or simple HTML markup, depending on your preferences and the complexity of the expression.

Math markup goes inside $$ ... $$

tags.

LaTeX pictures
You can also make pictures using LaTeX picture environment:

$$ \setlength{\unitlength}{.5in} \begin{picture}(10,10)(-5,5) \linethickness{1pt} \put(-2.5,0){\vector(1,0){5}} \put(0,-2.5){\vector(0,1){5}} \put(0,0){\circle{2}} \end{picture} $$

Creates:

$$ \setlength{\unitlength}{.5in} \begin{picture}(10,10)(-5,5) \linethickness{1pt} \put(-2.5,0){\vector(1,0){5}} \put(0,-2.5){\vector(0,1){5}} \put(0,0){\circle{2}} \end{picture} $$
