Title: good source for problems, but hard to learn from
Product review: I used Rosen's book for a Discrete Math course given at the sophomore level. If I had to sum this book up in few words, I would say, Short on explanations and examples, but long on exercises. I almost gave this book 3 stars because of the abundance of problems, but with the poor exposition and simple examples, I just couldn't in good conscience. My advice is to find another book from which to learn, but check out the problems to enhance your knowledge.
