Math Notation

Greetings to all,

A couple of weeks ago I started a series on game theory. Although I have written a few more posts for this series now, things have stalled somewhat due to my inability to write more complex mathematical formulas (equations, functions etc.) in blog-friendly format. I'm sure I could look around myself, but I thought I might ask: Does anyone know of any good online tutorials or resources on this issue? Or is it that the only way to do it by importing image files with the equations displayed on them?

Any information would be most appreciated.
