From the preface:

Elementary Algebrawas written with two goals in mind: to present the skills of algebra in the context of modeling and problem solving, and to engage students in an activity-based course.

Throughout the book, we use applications to motivate algebraic skills. We present ideas using verbal, numerical, and graphical tools. We use graphs extensively to illustrate algebraic techniques and to help students visualize relationships between variables. In the Homework Problems we break up skills practice into smaller sets of exercises and combine them with conceptual questions, graphing, and applications of various types.

Table of contents:

- Variables
- Linear Equations
- Graphs of Linear Equations
- Applications of Linear Equations
- Exponents and Roots
- Quadratic Equations
- Polynomials
- Algebraic Fractions
