- Algebraic-Graphical Side-by-Side Solutions give students a direct comparison between these two problem-solving methods. They demonstrate that there is more than one way to obtain a result and illustrate the comparative efficiency and accuracy of the two methods.
- Visualizing the Graph problem sets ask students to match equations and inequalities with their graphs. This helps students to recognize the important characteristics of the equation or inequality and visualize the corresponding attributes of its graph. This feature is animated in MyMathLab®, enabling the student to visualize concepts on an entirely new level.
- NEW! Chapter Openers pose real-world questions related to the chapter topics. Real data graphs help students analyze these questions and think about the answers.
- NEW! Your Turns offer calculator support at point of use. These simple exercises, designed to provide students with immediate keystroke practice, have been added to the in-text calculator instruction manual. Answers are provided after the exercises.
- NEW! Try Exercise icons, corresponding to nearly every example, point students to similar problems in the section exercise sets. By solving these problems, students can immediately reinforce their understanding of the mathematical concepts and skills presented in the examples. For easy identification in the exercise sets, the “Try” exercises have a shaded block on the exercise number. Answers to Try Exercises are given at the end of the exercise sets and in the back of the book.
- NEW! Mid-Chapter Reviews give students the opportunity to reinforce their understanding of the mathematical skills and concepts covered in the first half of the chapter before moving on to new material.
- Each Mid-Chapter Review begins with a Brief Summary of the concepts studied in the first part of the chapter, often illustrated with a table or chart.
- Guided Solutions problems with stepped-out solutions include fill-in blanks for students to complete the solution.
- Mixed Review exercises require an understanding of previously learned material to reinforce mastery of skills and concepts.
- NEW! Problem-Solving Steps, called out in the margins adjacent to selected Example Solutions, offer students at-a-glance reinforcement of the problem-solving process.
- The end-of section exercise sets include several special types of problems:
- Concept Reinforcement Exercises (also found in the chapter Study Summary) are True/False questions designed to increase understanding of the concepts rather than merely assess students' skill at memorizing procedures.
- “Aha!” Exercises discourage rote learning and reward students who “look before they leap” into a problem. The “Aha!” designation is used the first time a new insight can be applied to a particular type of exercise and indicates to the student that there is a simpler way to complete the exercise with less computation.
- TW (Thinking and Writing) Exercises promote conceptual understanding and can also be used for class discussion and group projects.
- Synthesis Exercises help build critical-thinking skills by requiring students to use skills and concepts from the current section along with those from previous sections. These are available in most exercise sets.
- The Connecting the Concepts feature helps students understand the “big picture,” by relating the concept at hand to previously learned and upcoming material.
- Interactive Discoveries invite students to develop analytical and reasoning skills while taking an active role in the learning process. These discoveries can be used as lecture launchers to introduce new topics at the start of a class and quickly guide students through concepts.
- Collaborative Corner exercises, appearing one to three times per chapter, are designed for group work.
- The Study Summary at the end of each chapter has been expanded to provide more comprehensive in-text practice and review. Key Terms and Concepts are paired with worked-out Examples for reference and review and similar Practice Exercises for students to solve.
- Mid-Chapter Reviews give students the opportunity to reinforce their understanding of the mathematical skills and concepts covered in the first half of the chapter before moving on to new material.
- Each Mid-Chapter Review begins with a Brief Summary of the concepts studied in the first part of the chapter, often illustrated with a table or chart.
- Guided Solutions problems with stepped-out solutions include fill-in blanks for students to complete the solution.
- Mixed Review exercises require an understanding of previously learned material to reinforce mastery of skills and concepts.
- The Study Summary at the end of each chapter has been expanded to provide more comprehensive in-text practice and review. Key Terms and Concepts are paired with worked-out Examples for reference and review and similar Practice Exercises for students to solve.

- Every exercise set has been carefully reviewed and revised to improve grading and pairing. Over 25% of the exercises are new, ensuring the right kind of practice for today’s students.
- Coverage of the Distance and Mid-Point Formulas has been added to Section 7.7.
- Solutions of quadratic equations (Section 8.3) are now covered before applications of quadratic equations (Section 8.4).
- All real data has been updated.
- Mini Lectures, now available in the Instructor’s Resource Manual, include learning objectives, teaching tips, and key examples for use in the classroom for each section of the text.
- Enhancements to MyMathLab include the following:
- Increased exercise coverage provides more practice options for students.

- Premade homework assignments will be available for each section of the text. In additional to the section-level premade assignments, the Bittinger MyMathLab courses will also include premade mid-chapter review assignments for each chapter.
- Interactive Translating for Success matching activities help students learn to associate word problems (through translation) with their appropriate mathematical equations. These activities are now assignable.
- Interactive Visualizing for Success activities ask students to match equations and inequalities with their graphs, allowing them to recognize the important characteristics of the equation and visualize the corresponding attributes of its graph. These activities are now assignable.
- The English/Spanish Audio Glossary allows students to see key mathematical terms and hear their definitions in either English or Spanish.
