Title: Too bad Amazon doesn't have negative stars
Review: I am a math major, and I bought this book, thinking that it would either be a humorous book, or what it claimed...a way to impress people. It was completely worthless. Do not bother with it.I know math is tough, and most people do not understand it at all. This book won't help you at all. It is wrong in places as well, and I mean basic stuff. Use with care!
