So anyway, when it became painfully obvious my brain couldn't handle higher math and I didn't need to carry around the forty-seven pound calculus book anymore, I figured this book, which indeed covers the fundamentals, would help me remember the skills I worked so hard at learning. Now I look at this book thirty years on, I recognize that it's all there, for indeed this book does present calculus in an straight forward way, and my brain just absolutely refuses to go there!
