Here are some other places to look more discrete-math-related material. If you have any other books or articles, list them here!
+ The Book of Numbers is a fascinating book that anyone can enjoy. The author, John Conway, is one of the few mathematicians who can write about math - and make it fun and inviting. This book doesn't deal with most of the topics we cover, but I would still highly recommend this book for anyone taking 375.
+ Concrete Mathematics is a book by Ronald Graham, Donald Knuth, and Oren Patashnik. This book is slightly more advanced that the textbook we are using. However, it provide many thorough explanations of the mathematics behind probability, sequences, and generating functions. You may find it useful as a second source.
