Title: A terrible book
Review: I cannot understand why at one time not to long ago this approach and this text were considered the way to go in math education. The explanations are unclear and often concepts are assumed before they are introduced. I tutor math at my university, and I have a terribe time trying to help tutor students in calculus because they're stuck with this abysmal book as a "guide." I would recommend the text by Zill if you can find it (it's out of print), but any other calculus text couldn't be worse than this one.
Is the review positive or negative?
