There's an easy way to add math to html so I don't see why it shouldn't work in a forum. Just include this in the "head" section of the html doc (or whatever the equivalent is for the forum software).
It's easy to use, there's a tutorial here:http://www.wjagray.co.uk/maths/ASCIIMathTutorial.html
The math should be enclosed by backticks ( ` ).
Here's an example of a complete html page with math. Just copy and paste into a text editor and save as "file.html", then open in a browser.

<p>When `a != 0`, there are two solutions to `ax^2 + bx + c = 0` and
`x = (-b +- sqrt(b^2-4ac))/(2a) .`
I think this would be a nice little feature for the forum, even though many don't think roulette has anything to do with math, LOL.
