Mathematical Formulas in HTML

With the start of my financial strategy course I need to find out how to add formulas to my HTML code in this blog. This will turn out to be interesting … and lots to read. I actually thought MathML would be a good solution but after this article I am not to sure anymore and this article talks about some other forms including the use of CSS. All in all, using simple images seems more and more clever, even though I do not want to use a million images and I actually want to indexed. So please, if anyone has a simple solution, I am all ears. In the meantime, this is pretty nice even if it gets really scary if you look at the source code ;)
