The coverage of this major topic contains some very positive features, notable the detail with which the examples are worked out, the extent and creativeness of the word problems, and the overall number of problems. The more advanced topics of matrix solutions and systems of three equations are not covered. The book adopts the attitude that the graphic method is both tedious and inaccurate. As such, the opening section on graphing simply talks about estimating the intercept, while the full discussion with definitions needed to address systems falls into the substitution section. The emphasis is thus decidedly on analytic approaches.
Problems are plentiful and often to medium levels, but the most difficult problems are less common.
In general, the quality of presentation, definitions of terms and concepts, clarity with which procedures are explained, and number of problems and detailed examples are outstanding. The topic could benefit from more difficult problems in some areas, and references to properties in working out examples and justifying steps. In general, however, the treatment of this major topic is sufficient to promote student achievement at all but the very highest levels. This major topic is addressed with clear explanations, lots of detailed examples, and lots of student exercises. Terms, concepts, and procedures are all clearly defined.
