Title: If you don't get it; he won't explain it
Review: This book does not offer a step by step explanation of its problems. If you don't get it; he doesn't explain how to solve the problem. He doesn't understand that writing out the answer is not teaching you how to solve the problem. He doesn't tell you why he does what he does to solve the problem. He just solves the problem and hopes you figure out what he's done. Personally, I'm not that good at math.
