This book is an introduction to the standard methods of proving mathematical theorems. It has been approved by the American Institute of Mathematics' Open Textbook Initiative. Also see the Mathematical Association of America Math DL review (of the 1st edition) and the Amazon reviews. An adoptions list is here.

Notice: On July 24, 2020, I issued edition 3.2 in print and PDF (ISBN's unchanged). This slight revision corrects a handful of typos found by readers. Also, after living with the red cover for two years, I switched to a more contemplative blue. All orders printed after July 24 will have the blue cover.

You can order a copy through Barnes & Noble or Amazon. Note: Currently Amazon sells only the hardback version. (Apparently their algorithm blocks the inexpensive paperback.) But you can order the paperback from Barnes & Noble. You can also download a free PDF version HERE. (The contents links below will take you to specific chapters in this file.)
Thanks to the readers who wrote to report mistakes and typos! I incorporate reader feedback in periodic revisions. Please contact me at rhammack@vcu.edu if you find any additional mistakes, no matter how minor.

Instructors and Readers: I'd like to post sample tests and additional exercises for Book of Proof on this page. Contributions are welcome! For more information, click on the link for ancillary material below.

Note to adopters: Your bookstore will need to know that the book is distributed by Ingram. Please let me know if you use Book of Proof in your classes and I will update the adoptions list. Thanks!
