Discrete Mathematics

The book is in excellent condition. It was shipped promptly and well packaged. The price was great. Thanks so much.

Shipment was sent to my son in college. I'm not sure how well it arrived or when it arrive, I just know it did arrive.

The most effective and best Discrete Mathematics book that I have found and used until now!!!I am taking a course in a computer science major and this is my textbook for this course. This is the only one math text that I honestly enjoyed from beginning to end. Dr. Johnsonbaugh has written an easily understandable, and remarkably thorough, introduction to discrete mathematics. This book covers all the topics of Discrete Mathematics that one would expect it to. In this book the reader will find topics ranging from logic and proofs, to algorithms, to counting methods and the pigeonhole principle, to recurrence relations, to graph theory, to trees, to network models, to Boolean algebra and combinatorial circuits, to automata, to grammars and languages, and to computational geometry. This book provides you all the materials and reasoning that provide strong preparation for computer science. You can use this book as a textbook, as a reference or as a self-study book. This is the most useful and effective book, which is suitable for readers with different backgrounds. To use this book, you do not need to have computer science, formal mathematics and calculus prerequisites. Dr. Johnsonbaugh has always been recognized for his lucid, accessible prose that explains complex, abstract concepts with clarity and precision, who is especially sensitive to the needs of the beginner in discrete math, and able to take you from the elementary to quite advanced levels in each topic. There is enough explanation to make you understand what is going on behind the mathematical symbols. This is the most structured, understandable and enjoyable discrete mathematics book, which provides worked examples, problem-solving corners, exercises and self-tests. All of these materials make it an wonderful experience to study Discrete Math.The book includes over 500 worked examples, which make the painful prospect of learning math much more palatable. The examples and explanations are clear, unburdened, and progresses nicely in different levels. Furthermore, problem-solving corners show students how to attack and solve problems and how to do proofs.3500 exercises, with answers to about one-third of them in the back of the book; Self-test with the answers to all questions in the back of the book; These exercises are designed to test your understanding and a few challenge problems are thrown in. This type of accessible difficulty in the problems builds your confidence and the solutions are a big help considering that Discrete Math is all about how you found the answer. On the whole, this an excellent, self-contained book written such that you will understand each page and concept if you have a reasonable attention span. Dr. Johnsonbaugh has made it as easy as possible for you. I strongly recommend this book to everyone who wants to study Discrete Math, which will benefit your whole career.

I was first exposed to this book (third edition) as a grader for a course that used the book. As such I had the fortunate ability to refer to the instructor's manual. I did read the book in as much as was necessary to feel like I had an understanding of where the students were coming from, but since I knew it all before reading it, for the most part, I didn't find it difficult at all. One of the perks of grading for that course was that I got to keep the book. I still have it, 8 years later as of the time of this writing, and find it a convenient reference when I want a quick easy definition of some fundamental concept that I've long forgot how to define because I've been working with that concept too much. I also refer to it when I want to stand back and see how some of these fundamental concepts tie in with each other, as the book does enable that (a little bit). I've always found the "cheat-sheet" of symbols on the inside covers useful. This isn't a "teach yourself discrete mathematics" book. Don't think it is. Hopefully you have a good instructor. Go to class, take notes, then, with your knowledge from class, go and try to do some of the problems, referring to the text when your notes are insufficient (and not insufficient because you fell asleep). If between your notes and memory of class and the text you still can't get it, go ask your professor for help. You should be able to do a few cycles of this between when an assignment is assigned and when it is due, in any course that this book is used in. If you can't, it either means the professor isn't allowing you enough time, or it means that you're not working often enough, or you need to take better notes, or you professor needs to give more help and/or better lectures. I think the book is fine. Do NOT use to teach yourself the material (as of the time of this writing, there were several bad reviews from students that appeared to have used it as such - perhaps through no fault of their own, as maybe the professor was insufficient in providing adequate notes). In summary - use either as a reference or in a course where the book's material is supplemental material to the course lectures.

I have taught using earlier versions of this book, and this looks like the best yet. I intend to use it for a topics course this summer. I asked to teach the course specifically so I could use this book. Unlike some other authors, Johnsonbaugh knows the territory and has done research in the area. He is also a great expositor and has assembled a lot of good exercises. The book can be used for several different types of courses. Five Stars!
