How do I format equations with LaTeX tags in forum posts?

[buhthestuh]

I'm sorry but I can't seem to figure out how to tag LATEX in my posts so that my equations in my posts come out in LATEX. What are the wrap tags for LaTeX on here. Is there a help section somewhere for these types of technical questions.

If you click on any equation, the source code with the [ t e x ] [ / t e x] (spaced out for viewing here) tags are revealed.

$$c^2=b^2+a^2$$ <--- click me

In the first forum "Math and Science Tutorials", there is the famous

"Introducing LaTeX Math Typesetting" thread.
