Math For Programmers 
I've never found any really good resource to learn Math from.<p>The problem I get is that whenever I see a big equation I tend to see a few greek symbols that I have never seen before and I have literally no idea whatsoever what they mean.<p>At least when looking at some unfamiliar code etc I can usually tell from function and variable names approximately what something is supposed to be.<p>Wikipedia is hopeless for learning because the math articles seem to be more interested in being complete and accurate than being accessible. When I hit a math page on something on wikipedia it tends to link off to a whole bunch of other pages on increasingly abstract parts of Math leaving me more confused than when I started.<p>I'd never have time to go through all of these topics and learn them properly, if I was going to do that I'd have become a mathematician.<p>Khan Academy is good, but seems to focus more on the mechanical skill of doing math rather than explaining concepts.
