This text provides a solid foundation in algebra with the exceptional pedagogy, clear and well-constructed writing style, superb problem-solving strategies, and other qualities that have made the Martin-Gay series so successful. The Second Edition features a greater incorporation of AMATYC and NCTM standards—reflected in an increased emphasis on visualization and graphing, carefully revised problems, and more data analysis. Also featured are current, relevant and realistic applications of math and its function in the world today.


Accessible Presentation.

  • Writing style is clear and direct.
  • Many clear explanations are provided.
  • Pedagogy is ample and accessible.
Treatment of graphing and scientific calculators is integrated in separate boxes and noted in exercise sets (one icon for graphing calculators, another for scientific). Instructors can pick and choose when and how they want to integrate technology into their course.
Mental Math boxes ask students to employ analytical skills and solve problems intuitively. They can be incorporated as in-class oral exercises or as preludes to exercise sets.
Definitions are clearly explained, both visually (definitions are summarized and highlighted by color) and by worked example. Ideal for visual learners, and/or for those who learn best by example.
Conceptual Exercises, identified by an icon, ask students to verbalize solutions, increasing students' “writing in mathematics” skills.
  • Also help develop pattern recognition.
Cumulative Reviews in every chapter include worked examples from previous chapters. Students can find the answers in an appendix, as well as a reference to where the problem first appeared so that a complete solution is available.
  • Similar Skill Reviews are featured at the end of every section.
Geometry concepts and applications are incorporated where appropriate.
NEWUnique chapter openers feature vignettes and related photographs demonstrating real-life applications of mathematics. Vignettes are summarized at ends of chapters with boxes stressing problem- solving and critical thinking skills.
  • Can be used as collaborative activities.
Group Activities at the end of chapters emphasize critical thinking and problem solving.
NEWA six-step problem-solving framework is woven consistently throughout. Students are asked to:
  • 1) Understand
  • 2) Assign
  • 3) Illustrate
  • 4) Translate into a model (equation)
  • 5) Complete
  • 6) Interpret—a variety of realistic problems.
NEWAn increased emphasis on data interpretation; real data is integrated throughout. With the emphasis on interpreting data via graphs, students reinforce what they've learned visually and see math's tangibility.
NEW—Basic concepts of functions are introduced early and intuitively. Students are gently eased into the concept of a function in Chapter 3, the concept of function is revisited as appropriate throughout the text.
NEWExercise sets have been carefully reviewed and revised to include more real data. The sets are graded in level of difficulty, and feature more conceptual and current data from environmental science, allied health, astronomy, business and other disciplines.
  • USA Today and other well-known sources are used.
NEWReminders (formerly Helpful Hints) alert students to trouble areas and provide encouragement and suggestions to avoid common errors.
