This title is a Pearson Global Edition. The Editorial team at Pearson has worked closely with educators around the world to include content which is especially relevant to students outside the United States.   Student-friendly features to make math accessible Margin Problems allow students to immediately practice the example material and check their answer at the bottom of the page in preparation for the exercise sets. Real-Life Applications with interesting data are used in many new or updated examples and exercises throughout the text. Students are often asked to find data in a table, chart, graph, or advertisement. These applied problems provide an up-to-date flavor that will appeal to and motivate students. Learning Objectives begin each section, and all material is keyed to these objectives to let students and instructors know exactly what will be covered. Pointers within examples, Cautions (highlighted in yellow) and Notes (highlighted in blue) provide students with important, on-the-spot reminders and warnings about common pitfalls. ·    Expanded! A popular feature, Pointers have been increased in this edition. UPDATED! Study Skills activities provide students with proven strategies for learning math. Many of these now include a Now Try This section to increase student involvement and accountability for the study skills activities. Vocabulary Tips in the margins of the first few chapters help students learn root words and prefixes. The new and engaging Chapter Openers portray real-life situations that make math relevant for students. Figures and Photos provide visual learners with a presentation of mathematical figures, diagrams, tables, and graphs whenever possible and use a style similar to that seen by students in today’s print and electronic media. These have been increased in this revision.   Calculator Tips are optional tips, marked with a red calculator icon, that offer helpful information and instruction for students using calculators in the course. Pedagogy that develops conceptual understanding alongside skill development Concept Checks at the start of exercise sets ensure students have the skills to proceed, and later help students consolidate learning by writing, correcting errors, and practicing processes. EXPANDED! Some Concept Checks include What Went Wrong Exercises, which have been expanded in this revision. Earlier editions of the text included exercises designed to help students find and fix errors, but in this edition these exercises have been updated and expanded with explicit instructions to emphasize the importance of this aspect of the learning process. When students can find and correct errors, they are demonstrating a higher level of understanding and conceptual knowledge. UPDATED! Relating Concepts exercises, located at the end of many section exercise sets, help students tie concepts together and develop higher-level problem-solving skills as they compare and contrast ideas, identify and describe patterns, and extend concepts to new situations. These exercises make great collaborative activities for pairs or small groups of students. Many more of these problem types have been included in the revision, and all Relating Concepts exercises are now assignable in the MyLab Mathematics course, noted with an “RC”. EXPANDED! Guided Solution exercises, noted with a “GS” in the margin and exercise sets, show the first steps of the solution process, providing guidance to students as they start learning a new concept or procedure. These exercises encourage understanding of the problem-solving process, rather than completing the

Guided Solution exercises, noted with a “GS” in the margin and exercise sets, show the first steps of the solution process, providing guidance to students as they start learning a new concept or procedure. These exercises encourage understanding of the problem solving process, rather than completing the steps by rote, and also keep students on the right track as they work through the problem-solving steps. Many of the Guided Solutions exercises in the end of section sets are assignable in MyLab Mathematics, and utilize a ‘guided’ functionality in the program. Coverage of these exercises in MyLab Mathematics has been increased in this revision. Examples and exercises have been adjusted or replaced with current data. Applications put math in context to motivate students and were updated to cover a wider variety of topics, including technology, ecology, and health sciences. The variety of end-of-section exercise sets provide students with opportunities to practice, apply, connect, and extend the skills they are learning. In addition to Chapter Review exercises keyed to sections from the chapter, Chapter Reviews include a full page of dedicated Mixed Review exercises, to help students synthesize concepts.   CONTENT CHANGES Specific content changes include the following: Exercise sets have been updated with a renewed focus on conceptual understanding, skill development, and review. New or revised figures are included wherever possible. Realworld data in the examples and exercises has been updated. More “word equations” are included in application examples to help students translate words into equations. Expanded Chapter R includes new figures and exposition on fractions, as well as new discussion, examples, and exercises on converting between fractions, decimals, and percents. Expanded Mid-Chapter Summary Exercises in Chapter 2 continue our  emphasis on  the difference between simplifying expressions and solving equations. The mid-chapter Summary Exercises in Chapters 4,6, and 9 include new examples that illustrate and distinguish between solution methods.   Summary Exercises in Chapter 2 continue our emphasis on the difference
