I'm convinced that math gurus are incapable of teaching math.

Whenever I encounter math textbooks like this one, I'm reminded of Underpants Gnomes on South Park. For the unwashed: Underpants Gnomes stole underwear from the residents of South Park hoping that they'd profit from the thefts, but although their business plan included a Phase 1 ("Steal underwear") and a Phase 3 ("Make a profit"), Phase 2—the connective tissue—was just "?".

I'm convinced that math gurus are incapable of teaching math.

Rosen and others like him fail to grasp how much "?" connective tissue they're leaving out when they "teach" math. He'll describe a math concept using almost-but-not-quite human language, then—oh, there's always a "then" with these books—the math gymnastics begin. Math teachers can't resist the gymnastics, can they? No, they really can't. At some point they lose their ability to see how much they assume other people know, and when that happens they cease being effective at teaching. This describes almost every math teacher I've had, and it definitely describes almost every math textbook that I've read. Rosen's book isn't the worst math textbook that I've read, but it's still pretty awful.

Seriously, corner cases and extreme mind-bending problems don't help people learn math; giving students time to grasp concepts before baffling them with bullshit does. This is why math schools like Khan Academy are amazing and college/university level math courses are not. This stuff can be taught, but not like this.

Recommends it for: non-mathematicians

tl;dr

If you open the book without a lot of theoretical math background, you'll have a good time with this book. It's written for computer scientists, so doesn't go heavy on the proofs and exact arguments, definitions, theorems, results, etc., but it makes itself relevant with many examples of how conepts are applied in CS.

Math people will probably be frustrated at the lack of depth, verbose yet fuzzy explanations, and redundant examples. You'll probably want something more concise.

tl;dr

Math people will probably be frustrated at the lack of depth, verbose yet fuzzy explanations, and redundant examples. You'll probably want something more concise.

Liked:

- (Usually) very accessible for people who aren't used to pure math (proofs, axioms, abstractness).
- Many illustrative, real-world examples
- Decent breadth of topics

Disliked:

- Skimpy proofs, interesting results are usually tucked away amongst the dozens of computational exercises. It's hard to figure out which problems are even worth doing.
- Too many examples. There are chapters where the vast majority of the text is just examples of the concept in action; in the graph theory chapter, there was a section with like 13 examples of basically the same thing.
- Shallow treatment of the math, sloppy definitions (he defines "clique" with the definition of the maximal clique), doesn't cover a lot of cool material that's appropriate to the subject.
- Slightly disorganized: the order in which graph theory concepts are described is awkward; you end up having to flip to the previous section, go through 12 examples to find a definition or theorem, and then flip back to the current page in order to remember what's going on.
- Doesn't acknowledge when facts are implicitly used despite not having been introduced yet.
- Not very good at explaining a lot of things, especially since his narration is inconsistent.

I used this text for my discrete math course. We covered six chapters and it was quite thorough. my major complaint with it is that Rosen can be portentous sometimes with his examples. He knows he knows this subject well and he wants to impress you all the time.

I think I will keep learning from the book and I would say all in all it's a good textbook. I really want to know more about discrete probability sooner rather than later.

The instances in which I was not very satisfied with this book have been very, very little so far. Or perhaps there was never one of them.

Quite frankly, differently from what I heard from several other reviews, I never had particular issues at either reading or following this book, except for the not uncommon overtime sometimes needed for finishing some of the exercises.

The best textbook found for Discrete Mathematics Course and a suggested textbook for Innopolis University Students.

Discrete Mathematics is a field of study integral to the Computer Sciences. It lays the foundations for mathematical thinking in its coverage of proofs, it dives into relevant aspects of application ranging from recursive algorithm structure to modelling networks and efficient systems architecture for modern computing.

This book should be the computer science standard for introductory to formal logic. It is easy to follow and ALOT of exercises to really create thicken those neural path in your head. Although, Calculus is not a prerequisite for this book, I still recommend having a concrete understanding of limits, differentiation, and integrals to really extract the most out of the exercises. After all, some important topics are also discussed in exercises.

As a non-mathematician, I am a bit overwhelmed by the difficulty of the problem sets towards the end of each set (usually around #45-60). I have found that some of the practice problems require knowledge that is either accessed in later subchapters or requires outside help to solve.

For example, null quantification is a concept introduced WITHIN the problem set for chapter 1.4. Wouldn't it make more sense to introduce the notion of null quantification (and how to go about solving it) in the subch

Regardless of my nit-picking, I plan on finishing the text as it is, from what I understand, the best introduction on the topic of discrete math for computer scientists.

Review of 8th Edition:

This book, and Susanna Epp's discrete mathematics with applications, are among the worst math textbooks I have ever seen.

* Poorly written and poorly organized

* Too wordy

* Essential points are in a single sentence hidden in the middle of paragraphs of page-long examples.

* You can't find a previously read topic in too much overly wordy description. Googling is much faster.

It's ridiculous that many classes use this book. It seems a strong connection occurred between teachers a

A great book with examples from contemporary times. The build up through the book is sustained with motivational examples and relevant references. As there are examples from various disciplines of computer science, it really helps you to draw parallels. A must read on this topic.

This book required me to supplement with other resources, but went far deeper than any others I found. At times, the author uses the phrase, "It is easy to see how ____," which often had me yelling at the book, "No, it's not!" but ultimately, I learned a great deal from this text.

Concepts of logic and the foundations of mathematics are communicated clearly. Excellent exercises with the solutions provided at the end of the book for each chapter. Nice book to reference every now and then when solving logic and math problems.

For the average student, this will do (it is especially well-suited for self-study). However, one thing that must be noted is the author's tendency to ramble. If you're looking for a concise reference book, this is not the one. For the average student, this will do (it is especially well-suited for self-study).

Read the 4th ed. nearly 20 years ago for a comp sci class. Ive referenced it here and there since then, and I am going through it again more thoroughly to brush up preparing for another class. Seems to be one of the standard discrete math texts. Definitely worth going through.

Someone decided all exercises? Next, book really useful and have great table in the introduction (14p) that can help you save time coz many of content is really very specific.
btw you can introduce yourself with Σ, ∀, ∃ and others interesting possibilities

"WHY STUDY DISCRETE MATHEMATICS? There are several important reasons for studying discrete mathematics. First, through this course you can develop your mathematical maturity: that is, your ability to understand and create mathematical arguments. You will not get very far in your studies in the mathematical sciences without these skills. Second, discrete mathematics is the gateway to more advanced courses in all parts of the mathematical sciences. Discrete mathematics provides the mathematical foundations for many computer science courses, including data structures, algorithms, database theory, automata theory, formal languages, compiler theory, computer security, and operating systems. Students find these courses much more difficult when they have not had the appropriate mathematical foundations from discrete mathematics." — 0 likes
