Query: Examples and problems constructed by inexperienced students

I have a master's degree in Electrical Engineering. I tutor students who are using this book in a community college course. In layout and in format, the book is very good. The concepts are presented in logical order, and the principles are usually explained well.My problem is that the examples and the end-of-chapter problems are full of errors. Example: Section P.6, "Rational Expressions" presents several examples to define the domain of an expression. Most of these conclude with the incorrect domain. This kind of sloppy editing can leave the student totally confused about a concept that is all-important to understand later concepts, such as systems of equations and series summations.I fully believe that the author left the basic book construction in the hands of inexperienced students. Its too bad that he did not bother with some double-checking of the work.
