## Description

This text makes a great supplement and provides a systematic approach for teaching undergraduate and graduate students how to read, understand, think about, and do proofs. The approach is to categorize, identify, and explain (at the student's level) the various techniques that are used repeatedly in all proofs, regardless of the subject in which the proofs arise. How to Read and Do Proofs also explains when each technique is likely to be used, based on certain key words that appear in the problem under consideration. Doing so enables students to choose a technique consciously, based on the form of the problem.

• The inclusion of a new Part II that contains a description of the mathematical thinking processes. As with the proof techniques, a name is given to each of the thinking processes which are then described at the student’s level with easy-to-understand examples. These examples, together with numerous exercises, are designed to give the student practice in understanding and using these thinking processes so that the student will be aware of these techniques when they arise in their subsequent math courses.
• Videotaped lectures for each proof technique that students can watch at their own pace on the web at www.wiley.com/college/solow/. To inform students how to read and do proofs.
"The instructional material is to the point, with well-considered examples and asides on common mistakes. Good examples of the author's thoughtfulness appear in the discourses on pp. 5-6 of identifying the hypothesis and conclusion when they are not obvious, on pp. 28-29 regarding overlapping notation, and on pp. 190-191 of the advantages and disadvantages of generalization." (Zentralblatt MATH 2016)

The inclusion in practically every chapter of new material on how to read and understand proofs as they are typically presented in class lectures, textbooks, and other mathematical literature. The goal is to provide sufficient examples (and exercises) to give students the ability to learn mathematics on their own.
