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), the Amazon reviews, and a brief news story on VCU InSight.

In this third edition, Chapter 3 on counting has been expanded and there is a new chapter on calculus proofs. Material has been edited for clarity, typos have been corrected, and some new exercises have been added. My decisions regarding revisions were guided by the Amazon reviews and many emails from readers.

The third edition will appear on Amazon and Barnes & Noble by October 2018. For now you can download a free PDF preview HERE. This version may undergo several minor tweaks before October. Please notify me if you find any typos!
