This section is satisfactory. Subtopics occur in a logical order, terms are generally well defined and concepts and procedures are clearly explained. Use of technology is appropriate. On the other hand, each section starts with a distracting exploration not clearly related to the topic at hand. The number and depth of problems at each stage is less than top level.
Word problems are weak.
There is little logical or proof-like development of the key points or why methods work. There is a lack of harder problems in most subtopics. There is a fair edging to moderately good coverage of this topic. Unfortunately, most of the material does not occur until chapter 12, making it likely that some classes will not get to this material. The general quality of the exposition is good and most subtopics occur in a reasonable order.
