I am in the process of reading Sklansky's "Getting the Best of it" now. It is not just math but it is math heavy. Simple formulas on how to get your permutations, combinations, and the like. It is not a poker only book so there is some other info about other gambling too but it focuses on poker mainly.

I also read Sklansky's "Theroy of Poker" which I would also recommend. The two of them make a pretty good combination and have helped me more than any other books for my usual game.
