As I've mentioned before, I didn't always like math -- and I don't claim to be an expert even now -- but nowadays I really enjoy learning more about the subject. Recently, I stumbled onto this site (the faq is particularly cool) while trying to figure out the comma placement on this site showing how to use an abacus (the number in question is where the virtual abacus displays its value -- and I still don't know).
Yet another cool site is this one about phonetic numbers -- that's where I heard about the abacus site.
Anyway, all of them make for interesting reading. Enjoy!
