[MathJax basic tutorial](https://math.meta.stackexchange.com/questions/5020/mathjax-basic-tutorial-and-quick-reference).

Unfortunately, a couple things on this tutorial don't apply on the Azimuth Forum! Most importantly:

* For "displayed" equations, centered on the page, use double dollar signs: `$$E = \sqrt{m^2 + p^2}$$`.

* For "inline" equations, mixed in with your text, use this method: `\\(E = \sqrt{m^2 + p^2}\\)`.

* You may need to hit "refresh" on your browser to see the LaTeX symbols rendered as math.
