There are many answers to problems for students to check their own work. There are many pictures within the text beyond those that clearly illustrate the material being presented. The student text includes self-testing sections. This is a fair coverage of this topic. The order of subtopics is generally good, but extraneous subtopics tend to interfere with continuity.
Terms are generally well defined and clear descriptions are present.
Unfortunately, much of the clarity may be lost amidst an over emphasis on manipulatives and calculators. Problem sets barely enter the middle level of difficulty. Most sections are introduced with a story that does not really lead well to the topic. One such introduction introduces a completely irrelevant topic. Neither understanding of algebra nor of the logic of the computer is required.
