This revision of the companion to Elementary Algebra, rounds out this hardcover developmental mathematics series. The second edition retains its four-color pedagogical system and now provides early coverage of graphing linear equations in two variables and linear functions (Ch 3). A real-life application entitled, "Real World Connections" opens each chapter. This application is revisited after the mathematics needed to solve it have been presented. Writing exercises, entitled "Say It In Words", "Warm Up" problems, and group exercises, entitled "Team Projects" have been added. "Graphing Calculator Crossover" boxes provide optional graphing calculator material where appropriate, while "Learning Advantage" boxes offer helpful study hints. Examples include solutions/explanations highlighted in color. Some examples feature "boxed" material indicating steps students may perform mentally after achieving a certain level of proficiency. After presenting specific procedures, "Strategy" boxes explain and summarize the techniques involved, and serve as references students may consult when working on exercise set problems. Exercises have odd-even pairing, are organized in graded levels of difficulty, and in addition to integers, stress fractions and decimals. Problems designed to be solved with a scientific calculator are denoted.
