Negative Positive
Title: Not helpful
Review: This is perhaps the worst book ever written, ever. I was forced to buy this book for my class and I have regretted every penny I've spent on this "book." Needless to say, I do not recommend this at all. It skips many steps in its example problems. It doesn't even explain how to take a determinent of a 3 x 3 matrix. It assumes that you remember that. So, for the love of God, stay away.
