1. Open the article in edit mode and switch to "wiki text editor"

2. Click on "Mathematical formula (LaTeX)"

The Wikitext code for an example formula looks like this:

 <math>
 \operatorname{erfc}(x) =
 \frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt =
 \frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}}
 </math> 

Which results in a formula like this:

$\operatorname {erfc} (x)={\frac {2}{\sqrt {\pi }}}\int _{x}^{\infty }e^{-t^{2}}\,dt={\frac {e^{-x^{2}}}{x{\sqrt {\pi }}}}\sum _{n=0}^{\infty }(-1)^{n}{\frac {(2n)!}{n!(2x)^{2n}}}$

What you see is:

• The overall formula needs to be enclosed by $and$ tags.
• The formula itself is written in (rather complicated to understand for first-time users) LaTeX code
