Query: Not the best math textbook

As a comprehensive book on discrete math I really found this text lacking. At times some examples were vaguely illustrated or maybe omitted altogether.If you're using this for a discrete math class, hopefully your instructor has enough supplemental material to carry the text, but I'm not as lucky. Doing an independent study of the course that used this text meant using Google a lot.I also have the next edition, and I can say that there is hardly a difference as far as the lack of examples and overall clarity.
