Title: seriously come on
Review: I don't even understand how a textbook like this can be printed with so many errors in it. Even some key equations are riddled with errors that have to be tracked down. It is a major waste of time trying to find where the author went wrong in the example problems. If you can't get the basic algebra correct consistently, why should I trust what you say about anything in this book? If you get stuck with this book for a course I really pity you.
Is the review positive or negative?
