Synopsis

This text reinforces the major concepts of algebra through a combined traditional/reform approach. The text's vocabulary, practice drills, and well-defined pedagogy are akin to a traditional book, while its focus on problem solving, reasoning, communicating, and technology should make it appealing to followers of reform as well. The book's foundation is a group of fundamental algebraic concepts that students should learn to master by the end of the course. Through numerous examples and exercises, students learn how to read, write, and think mathematically.
