Review title: Okay if you know what you're doing already
Product review: I ordered this book as I needed a step by step refresher of everything mathematics including order of operations for algebraic expressions. This book is great if you need some extra problem sets to help enhance what you know. If you have forgotten how to do the math and need a step by step refresher, do not buy this book. The author sets up the example without explaining why it is set up that way and then gives an answer to the problem without showing how it is solved. It leaves somebody like me very frustrated.
