Review Text
This textbook could be useful as a workbook, because it has a lot of problems with the answers in the back. If you want some practice and need to know if you are getting the right answers, then this book might be a good choice.Unfortunately, the instructional portion is quite poor. Space is wasted providing the biographies of different mathematicians. Additionally, the "examples" rarely give insight into how to actually solve the problems.If you are using this textbook, I recommend doing an Internet search to learn how to actually solve the exercises. There are some good web resources out there that will explain what you need to know to answer the questions in this book.
This textbook is one of those that you don't buy unless your professor requires that you do so.The book does explain discrete math to some degree. It does take you through truth tables, proof by contradiction, set theory, and so forth. I found the examples to be generally limited (and weak) and the back of the book avoided any type of solution.. only answers.I remember struggling to understand his explanations of uncountable sets, and his explanations of modular mathematics. In fact, the section on mod. math bothered me the most. I really wish the author's writing could have been a bit more accessible/meaningful.Besides those issues, the book isn't completely worthless. If you read through it, you will learn quite a bit. I found that I could have learned much more with other books. Furthermore, the price for a new copy is downright ridiculous; I don't even think I'd spend $50 on such a textbook (yes, even if new) when I could get much better and much more effective textbooks elsewhere.I wanted to give this book 3 stars out of 5, but seeing that it's the exact same material (but maybe worse in some areas) as the 6th edition, I will go with the 2. Truth be told, you can find a much better discrete math book for 20% of this book's cost.Hope this helps... please feel free to ask any questions.
This book is complete garbage!I am a computer science major, and I love math. I am an "A" student in math all the way through calc II. So my bad review is not because I hate the subject. I actually find it very interesting.This is the most horrible text book I have ever been subjected to use in my life. I have over 100 credits. It is incredibly huge, and all the pages are completely filled with text. If you have to read a chapter that is 20 pages, it's really 40. If you are like me and get stuck doing 5 chapters in one week, you're f*****So what's wrong with this book.... A better question might be, what is good about the book. Then I could just say nothing.1. It's written in a completely cryptic language, that makes it impossible for the average human to understand. Any simple concept can be drawn out across 2 pages and just be completely filled with equations that are 20 characters long. Basically there are not many words, the book is written almost completely in equations that make no sense because they never explain them.2. Parts are cut out, so you have no idea what to do. The book says I will cut out some obvious parts, very sparingly. As soon as that happens you will read something that says something to the matter "so you see", or "obviously". NO! I don't see and it's not obvious, please explain it you F***TARD!!!.3. There are no good examples in the book. You will read the text as slow as possible, and when you get to the end you will think you understand SOMETIMES. Well, you won't, the homework questions are much harder than the examples, if you even get any. Basically, to explain in simple terms, the book will give you something along the lines of 100 divided by 5, as an example, and the question in the back will be long division. It gives you the least amount of tools, in, incredibly hard to understand, longwinded wording, and expects you to make miracles happen.I hate this book with a burning passion. The concepts are all so easy, but this book makes it IMPOSSIBLE to grasp. It's like this guy wrote this to make your life miserable. I would rather clean excrement with my bare hands then ever have to open this book again. I seriously mean that. This book is going to ruin my scholarship I worked so hard for.I highly suggest, if you are forced to use this book, have the option open to get a tutor just in case. Or be prepared to use the tutor lab. That is the only way you will survive.

The book is written in a complicated and didactic language that successfully translates an abstract math subject into boring and confusing nonsense. The author seems want to use this book to pretentiously boast his profound understanding about this subject rather than demonstrating it in an easy way. Can't really understand the definitions and examples unless you read several times. Problems after the chapters are totally unrelated to the given examples. And the layout are just messy. All examples, solutions, illustrations are totally blended together that cannot be distinguished from one and another, let alone to know their importance. Confusing, obscure, awful, extremely expensive, bulky. Have already bought another book(by Susanna) to study instead of using this one. I have to say Susanna's book is way better than this one. I am very disappointed by McGraw Hill, the author and my college. I don't know how can this book be published, they are too irresponsible. It should never be used as a textbook, it is not an introductory book for students. WORST TEXTBOOK EVER. DON'T RECOMMEND IT TO OTHERS. DON'T WASTE YOUR TIME AND MONEY.
