If you are being literal, than I'd suggest any grade school math book in your library. Assuming you actually mean that you know algebra/trig (or can review these quickly), I'd suggest a good calculus book. I don't know any off hand, but I'm sure someone here can suggest. Assuming you know calculus and you want to learn what you have heard of as "real math" there are a few options. 1) You can pick up a good linear algebra book 2) Pick up a book on discrete mathematics 3) Pick up a book on introductory analysis. I guess a big question is why do you want to do this? For fun? For your job?
