This book is very confusing. The reader is required to make very large leaps to relate example to exercise. Most of these leaps (chap 2-6) involve wading through set theory instead of applying what was covered in a given chapter. It seems as if the questions are designed so the reader must figure out some "trick" in order to solve the problem. This book may be useful if the reader is very familiar with logic notation, set theory, and linear algebra; otherwise, you will probably spend a lot of time learning these things from other sources.
