My professor wrote his own textbook, 'cause he wasn't happy with the ones on the market. Sorry to break his bubble, but he can't write a textbook for crap - it's very hard to understand, and doesn't define many of the symbols or figures he's using. It's Boolean Logic, a sort of Computer Science / Mathematics hybrid. When asking for advice on this subject (As I'm going to have to do fairly often), which forum should I post in for it? It's not really pre-Calculus, but it's not part of Calculus either. Other Sciences? Maybe. I figured it'd be better to ask.
