Title: worst mathematics textbook I've even encountered
Review: Rosen claims the book is error-free, yet my copy was riddled with nonsensical errors. His examples & discussions are mostly trivial. There are some very challenging problems in the exercises that went beyond the scope of the presented material, though, and these were the assigned problems. I did not know of one student who did not despise this text, as well as the course, wholeheartedly. People in the library would shout out loud, "I HATE THIS BOOK. I HATE THIS COURSE!" I have never encountered such distaste for any other book or course in my academic career. I do not understand why this book is used; why not just use Knuth instead--he is a far superior communicator.
