About the Book
  • Engaging applications and real-world data put learning into context. Bob Blitzer is on a constant search for data that can be used to illustrate algebra applications. He has used this research to update the chapter- and section-opening applications, examples, and exercises in the text.
    • NEW AND UPDATED! More than 100 new or revised examples, applications, and exercises are based on new or updated data sets. Many of these applications involve topics relevant to college students, such as the number of hours college students sleep and tuition costs, while others tackle larger issues such as climate change and mental illness.
    • Blitzer Bonuses are features that provide interesting connections to the math at hand, showing students that math is a dynamic discipline applicable to the real world.
      • These features have been integrated into MyMathLab, with new engaging Blitzer Bonus videos to connect the math to the real world in a visual way, and are assignable with corresponding assessment exercises to ensure that students watched the video and understood the topic at hand.
  • Additional study skills support is available to students through in-text features and the updated Learning Guide:
    • Great Question! presents helpful study tips in the form of a question a student might have. Answers to the questions offer suggestions for problem solving, point out common errors to avoid, and provide informal hints and suggestions.
    • Achieving Success boxes offer strategies for success in math courses, along with suggestions to help developmental students achieve their full academic potential.
    • UPDATED! The Learning Guide helps students make the most of the Blitzer program. This workbook gives students the opportunity to practice the topics, with side-by-side examples and practice problems, and guidance for test preparation. New projects foster conceptual understanding in an active classroom environment, and are included in the Learning Guide. The Learning Guide is available for students in MyMathLab, or as a printed, unbound workbook.
  • Explanatory Voice Balloons translate algebraic ideas into everyday English, help clarify problem-solving procedures, present alternative ways of understanding concepts, and connect problems-solving strategies to concepts students have already learned.
  • Check Point exercises, after every example, make the text more interactive by offering students the opportunity to test their understanding of the example by working a similar exercise. Answers to all of the Check Points are in the answer section.
  • Extensive exercise sets offer several types of exercises. This variety makes it easy to create well-rounded homework assignments from the text or in MyMathLab. Exercise types include the following:
    • Concept and Vocabulary Checks provide fill-in-the-blank and true/false exercises that assess students' understanding of the definitions and concepts presented in the section. These are also assignable in MyMathLab.
    • Practice Plus Problems are more challenging exercises that require students to combine several skills or concepts.
    • Explaining the Concepts exercises ask students to explain terms and concepts in their own words, helping them to develop a mathematical vocabulary.
    • Critical Thinking Exercises stretch student thinking by taking concepts one step further, while asking students to draw conclusions and justify answers. Make Sense and True/False exercises also fall under this category.
    • Review Exercises review previously covered topics to improve and maintain students' understanding and mastery of the material.
    • Preview Exercises help students prepare for the following section by previewing the concepts that they will soon encounter.
    • Application Exercises allow students to apply the skills they’ve learned to a realistic or interesting scenario.
    • Technology Exercises are meant to be used with a graphing utility, reinforcing graphing calculator skills developed in the section.
  • Mid-Chapter Check Points allow students to stop and assess the skills and concepts they've learned separately over several sections. The Mid-Chapter Check Points will now be available as a pre-made assignment in the Blitzer MyMathLab courses.
  • Chapter Summaries are organized by section and highlight important concepts and topics with side-by-side examples to make it easy for students to study and check for mastery of key concepts.

Bob Blitzer is a native of Manhattan and received a Bachelor of Arts degree with dual majors in mathematics and psychology (minor: English literature) from the City College of New York. His unusual combination of academic interests led him toward a Master of Arts in mathematics from the University of Miami and a doctorate in behavioral sciences from Nova University. Bob’s love for teaching mathematics was nourished for nearly 30 years at Miami Dade College, where he received numerous teaching awards, including Innovator of the Year from the League for Innovations in the Community College and an endowed chair based on excellence in the classroom. In addition to his Developmental Algebra Series, Bob has written textbooks covering college algebra, algebra and trigonometry, precalculus, and liberal arts mathematics, all published by Pearson Education. When not secluded in his Northern California writer’s cabin, Bob can be found hiking the beaches and trails of Point Reyes National Seashore, and tending to the chores required by his beloved entourage of horses, chickens, and irritable roosters.
