Textbook and Materials

There are four textbooks required for this course. The first three are free OER books which can be downloaded. The fourth can be purchased in either electronic or hard copy for around $20. There is much overlap between textbooks, but each has gaps which are filled by others.

1. The Doerr textbook contains all the required topics, but some of its explanations are not ideal and the exercise sets are limited.
2. The Kwong textbook does not contain all the required topics, but it gives a clear overview of discrete mathematics and contains clear motivations for proofs.
3. The Levin textbook does not contain all the required topics, but it gives clear explanations of several proof techniques and motivates the topics that it does contain.
4. The Lipschutz textbook contains all required topics, with concise and clear definitions and theorems, many solved problems, and many supplementary problems with answers. It does not emphasize proofs and the theoretical discussions are brief.

In each unit, you will be pointed to the relevant sections, if needed, for each text. The links and bibliographic information for each text are listed below.
