To the Instructor We share a partnership with you. For over thirty years we have taught mathematics courses at North Shore Community College. Each semester we join you in the daily task of sharing the knowledge of mathematics with students who often struggle with this subject. We enjoy teaching and helping studentsand we are confident that you share these joys with us. Mathematics instructors and students face many challenges today. Intermediate Algebra was written with these needs in mind. This textbook explains mathematics slowly, clearly, and in a way that is relevant to everyday life for the college student. As with previous editions, special attention has been given in the fourth edition to problem solving. This text is written to help students organize the information in any problem-solving situation, to reduce anxiety, and to provide a guide that enables students to become confident problem solvers. One of the hallmark characteristics of Intermediate Algebra that makes the text easy to learn and teach from is the building block organization. Each section is written to stand on its own, and each homework set is completely self-testing. Exercises are paired and graded and are of varying levels and types to ensure that all skills and concepts are covered. As a result, the text offers students an effective and proven learning program suitable for a variety of course formatsincluding lecture-based classes; discussion-oriented classes; distance learning centers; modular, self-paced courses; mathematics laboratories; and computer-supported centers. Intermediate Algebra is part of a series that includes the following: Tobey/Slater, Basic College Mathematics, Fourth Edition Blair/Tobey/Slater, Prealgebra, Second Edition Tobey/Slater, Beginning Algebra, Fifth Edition Tobey/Slater, Beginning and Intermediate Algebra We have visited and listened to teachers across the country and have incorporated a number of their suggestions into this edition to help you with the particular learning delivery system at your school. The following pages describe the key continuing features and the key changes in the fourth edition. Key Features and Changes in the Fourth Edition Developing Problem-Solving Abilities We are committed as authors to producing a textbook that emphasizes mathematical reasoning and problem-solving techniques as recommended by AMATYC, NCTM, AMS, NADE, MAA, and other groups. To this end, the exercise sets are built on a wealth of real-life and real-data applications. Unique exercises that help train students in data interpretation, mental mathematics, estimation, geometry and graphing, number sense, critical thinking, and decision making have been developed and incorporated into the exercise sets. More Applied Exercises The exercises and applications have been extensively revised. Numerous real-world and real-data application exercises show students the relevance of the math they are learning. The applications relate to everyday life, global issues beyond the borders of the United States, and other academic disciplines. Many include source citations. Nearly 50 percent of the applications are revised or new. The number of real-data applications has significantly increased. Many applications were contributed by actual students based on scenarios they encountered in their home or work lives. Math in the Media New Math in the Media applications appear at the end of each chapter to offer students yet another opportunity to see why developing mastery of mathematical concepts enhances their understanding of the world around them. The applications are based on information from familiar media sources. Students may interpret or verify information, perform calculations, make decisions or predictions, or provide a rationale for their responses. Putting Your Skills to Work Applications This highly successful feature has been revised in the fourth edition. There are eleven new Putting Your Skills to Work applications in the new edition. These nonroutine application exercises challenge students to synthesize the knowledge they have gained and apply it to a totally new area. Each exercise is specifically arranged for independent and cooperative learning or group investigation. Students are given the opportunity to help one another discover mathematical solutions to extended exercises. The investigations feature open-ended questions and extrapolation of data to areas beyond what is normally covered. Internet Connections As an integral part of each Putting Your Skills to Work exercise, students are exposed to an interesting application of the Internet and encouraged to continue their investigations. This use of technology inspires students' confidence in their abilities to successfully use mathematics. In the fourth edition, the Internet Connections have been completely revised and updated. The companion Web site http://www.prenhall.com/tobey_intermediate now features annotated links to help students navigate the sites more efficiently and to provide a more user-friendly experience. Increased Integration and Emphasis on Geometry Due to the emphasis on geometry in many statewide exams, geometry exercises are integrated throughout the text. The new edition contains approximately 20 percent more geometry exercises. Additionally, examples and exercises that incorporate a principle of geometry are now marked with a triangle icon for easy identification. Developing Your Study Skills This highly successful feature has been retained in the new edition. The boxed notes are integrated throughout the text to provide students with techniques for improving their study skills and succeeding in math courses. Graphs, Charts, and Tables When students find mathematics in real-world publications, they often see data represented in a graph, chart, or table and are asked to make a reasonable conclusion based on the data presented. This emphasis on graphical interpretation is a continuing trend with the expanding technology of our day. Therefore, the number of mathematical exercises based on charts, graphs, and tables has been significantly increased in this edition. New Design The fourth edition has a new design and art program that enhances the accessible, student-friendly writing style. See the walk-through of features in the preface. Mastering Mathematical Concepts Text features that develop the mastery of concepts include the following: Learning Objectives Concise learning objectives listed at the beginning of each section allow students to preview the goals of that section. Examples and Exercises The examples and exercises in this text have been carefully chosen to guide students through Intermediate Algebra. We have incorporated several different types of exercises and examples to assist your students in retaining the content of this course. Chapter Pretests Each chapter opens with a concise pretest to familiarize students with the learning objectives for that particular chapter. The exercises are keyed to the appropriate sections of the chapter. All answers appear in the back of the book. Practice Problems Practice Problems are found throughout the chapter after the examples and are designed to provide students with immediate practice of the skills presented in the examples. The complete worked-out solution to each Practice Problem appears in the back of the book. To Think About These critical thinking questions follow some of the examples in the text and also appear in the exercise sets. They extend the concept being taught, providing the opportunity for students to stretch their minds, to look for patterns, and to make conclusions based on previous experience. The new edition includes approximately 30 percent more of these exercises. Exercise Sets Exercise sets are paired and graded. This design helps ease the students into the exercises, and the answers provide students with immediate feedback. Cumulative Review Problems Each exercise set concludes with a section of Cumulative Review Problems. These exercises review topics previously covered and are designed to assist students in retaining the material. Many additional applied exercises have been added to these sections. Graphing and Scientific Calculator Exercises Calculator boxes are placed in the margins of the text to alert students to a scientific or graphing calculator application. In the exercise sections, icons indicate exercises that are designed for solving with a graphing or scientific calculator. Reviewing Mathematical Concepts At the end of each chapter, we have included exercises and tests that provide students with several different formats to help them review and reinforce the ideas that they have learned. This not only assists the students with the present chapter but also reviews previously covered topics. Chapter Organizers The concepts and mathematical procedures covered in each chapter are reviewed at the end of the chapter in a unique Chapter Organizer. This device has been extremely popular with faculty and students alike. It not only lists concepts and methods but also provides a completely worked-out example for each type of exercise. Students often find that preparing a similar chapter organizer on their own in higher-level math courses becomes an invaluable way to master the content of a chapter of material. Verbal and Writing Skills These exercises provide students with the opportunity to extend a mathematical concept by allowing them to use their own words, to clarify their thinking, and to become familiar with mathematical terms. Chapter Review Problems These exercises serve as a quick refresher at the end of each chapter. They can also be used by the student as a quiz of the chapter material. Tests Found at the end of each chapter, the Chapter Test is a representative review of the material from that particular chapter and simulates an actual testing format. Cumulative Tests At the end of each chapter is a Cumulative Test. One-half of the content of each Cumulative Test is based on the math skills learned in previous chapters. By completing these tests, students build confidence that they have mastered the concepts of the present chapter as well as concepts from previous chapters. Additional Content Changes in the Fourth Edition In addition to the improvements listed previously, the new edition contains the following changes. Throughout the text, explanations, definitions, and procedures have been carefully revised for greater clarity and precision. The discussion in Chapter 2 of solving linear equations now includes coverage of equations with no solution and equations with infinitely many solutions. To help prepare students better for college algebra, the concept of a function (first discussed in Chapter 3) is now integrated into Chapters 5, 6, and 7, where we discuss polynomial, rational, and radical functions. As in the previous edition, functions are also discussed in Chapters 8 and 10. The sections on determinants and Cramer's rule have been moved from Chapter 4 to Appendix B. This material can be covered with ease after Section 4.3. Expanded and Enhanced Supplements Resource Package The fourth edition is supported by a wealth of new supplements designed for added effectiveness and efficiency.
