testing latex javascrip code.

I came across watchmath, and supposedly there are instructions to make latex code work on blogger. Specifically, something like $f(x)=x^2$ should look nice right now. I'm not sure if it is working though. Hmm... what about $$f(x)=x^2$$? What about ${f(x)=x^2}$?

I see, my template was causing some problem. Appologies for the ugly template, but now I can use latex code.
