Query: Skip this one

You'd think with how important it is to understand each step in solving a math problem, that a math text wouldn't skip any.Not so! This book routinely skips past steps. You'll find signs flipped, things factored, and numbers changed with no explanation.You sometimes end up with an answer that is technically the same as what the book's example has, but signs will be flipped in the book. Sometimes the answer is completely off, and it's because you followed the book's incomplete instructions. It's like they never handed this book to someone who doesn't already know everything in it before putting it up for sale.Skip this if your course gives the option.edit:This is based on the 4th edition, but given the nature of the textbook publishing industry, the 5th edition is probably the same book with a new cover.
