What is your recommendation for an in-depth introductory combinatoric book? A book that doesn't just tell you about the multiplication principle, but rather shows the whole logic behind the questions with full proofs. The book should be for a first-year-student in college. Do you know a good book on the subject?

Thanks.

    Thanks for asking this question. It really help me out narrow my search in good introductory Combinatoric books. I'd like to add two other books: How To Prove It by Velleman and How to Solve it! by Polya both are valuable books that could help undergrads taking upper division subjects like Combinatorics.2015-01-12
