Charles Wright Books

This is one of the worst books I ever purchased for a class (4th edition). The price is ridiculous and entirely undeserved. These authors take simple subjects and make them incomprehensible. The introduction to proofs in chapter 2 is a perfect example. They try to expose the concepts thru chatty dialog and fail miserably. The student is left more confused than before they read the material. Rosen's book is a lot better.

If this book is required for your course, then it means the publishing company's marketing machine has won over someone powerful in the department under which your course is managed.

It's sick how such a crappy book can "convince" many course coordinators to make it a required textbook. This book is marketed very well like James Stewarts' Calculus books (table props), but it's even worse than what Stewart puts out (hard to imagine!).

I was a student of Mr. Ross's, taking Discrete Math, a few years ago. He's is a very intelligent man and seemed to enjoy teaching. Unfortunately, he was not very good at it. And same goes for this text book of his. His attitude and approach in the classroom and the book's alike might be helpful if the student has already mastered the majority of the covered topics, in which case, this book becomes useless.

This book will cost you much more than the principle "investment" of $100+, given the time required to interperet Ross's examples, and in many cases, un/re-learn the material.

I keep thinking as I'm forced to use this book for a college course, that Discrete Math would not be so confusing to me if not for this textbook. With a good textbook, I believe the concepts would not be very difficult, but this book makes them so. True, they have many examples - very few of which cover the complex things you are then asked to do in the Exercises. If I could give it negative stars, I would, since it doesn't teach us but confuses us.
