Algebra is like a foreign language for many students. They have difficulty translating the words, their definitions and how it applies to problem-solving. Tussy/Gustafson's ELEMENTARY AND INTERMEDIATE ALGEBRA, 6th Edition, addresses these concerns, giving you the tools needed to understand the language of algebra. Strategy and Why explanations in the worked examples show the "how" and the "why" behind problem-solving. Algebra is not just about the x -- it's also about the WHY. The text contains many opportunities to apply the algebraic skills you have learned to solve a wide variety of interesting real-life applications using a six-step problem-solving strategy. In combination, the text and WebAssign will guide you through an integrated learning process that will expand your reasoning abilities as it teaches you how to read, write and think mathematically using the language of Algebra.

• Alan S. Tussy

Alan Tussy has taught all levels of developmental mathematics at Citrus College in Glendora, CA. He has written nine math books. An extraordinary author dedicated to his students' success, he is relentlessly meticulous and creative—a visionary who maintains a keen focus on the greatest challenges students face in Mathematics. Alan received his Bachelor of Science degree in Mathematics from University of Redlands and his Master of Science degree in Applied Mathematics from California State University, Los Angeles. He has taught across course and curriculum areas from prealgebra to differential equations. He is currently focusing on teaching courses related to Developmental Mathematics. Professor Tussy is a member of the American Mathematical Association of Two-Year Colleges (AMATYC).

• R. David Gustafson

R. David Gustafson is professor emeritus of mathematics at Rock Valley College in Illinois and has also taught extensively at Rockford College and Beloit College. He is coauthor of several best-selling mathematics textbooks, including Gustafson/Hughes' COLLEGE ALGEBRA, Gustafson/Karr/Massey's BEGINNING ALGEBRA; INTERMEDIATE ALGEBRA; BEGINNING AND INTERMEDIATE ALGEBRA; BEGINNING AND INTERMEDIATE ALGEBRA: A COMBINED APPROACH; and the Tussy/Gustafson and Tussy/Gustafson/Koenig Developmental Mathematics series. His numerous professional honors include Rock Valley Teacher of the Year and Rockford's Outstanding Educator of the Year. He has been very active in the American Mathematical Association of Two-Year Colleges (AMATYC) as a Midwest vice president. He has also served as president of IMACC, AMATYC's Illinois affiliate. Professor Gustafson earned a master of arts from Rockford College in Illinois as well as a master of science from Northern Illinois University.

• *NEW* UPDATED REAL-LIFE EXAMPLES with a multitude of new application problems that deal with current topics today’s math students might encounter in their everyday lives have been added.

• *NEW* UNIQUE "STEP-BY-STEP" PROBLEM TYPE is available. It is designed to improve students’ ability to read and write the language of algebra. This instructional feature gives students all of the steps used to solve a problem and then determine the correct order.

• *NEW* GROWTH MINDSET is encouraged by identifying errors in mathematical solutions. To promote a growth mindset, many "Study Sets" now contain "Find It" problems where students are asked to spot any errors, justify their reasoning and solve the problem correctly. "Find It" problems contain both conceptual and computational errors.

• *NEW* SALARY FIGURES AND JOB OUTLOOK INFORMATION are updated in the "from Campus to Careers" chapter-opener features. Several new careers have been inserted such as physical therapy assistant, robotics technician, web designer, nurse practitioner and construction manager. Associated application problems for all of these vocations are included in the "Study Sets."

• *NEW* MORE GRAPHS INCLUDED to communicate important quantitative information in a visual format. Knowing how to interpret graphs has become a crucial skill to have in the workplace. For this reason, many more graphs have been included in the "Study Sets" that call for students to do just that -- read and interpret a wide variety of graphs (and illustrations) of real-life situations.

• *NEW* EYE-CATCHING CAUTION BOXES have been added to sections in Chapter 7 to stress the importance of factoring when simplifying rational expressions and solving rational equations.

• WEBASSIGN ONLINE COURSE SOLUTION provides support for you and your students. Fully integrated with this printed edition of the text, WebAssign offers both a powerful online homework and a course management system that engages students in learning math. Pre-built assignments (Course Packs), just-in-time remediation (Learn Its) and unique question types (Responsive Questions and Concept Checks) vetted by trusted subject matter experts help you foster a deeper understanding of course concepts.

• THE LANGUAGE OF ALGEBRA BOXES draw connections between mathematical terms and everyday references to reinforce the language of algebra thread that runs throughout the text.

• TEACHING TIPS have been placed at strategic places in the margins to offer instructional suggestions that can be employed during classroom presentations. In addition, each worked example has an accompanying "Teaching Example" that instructors can use as part of a classroom lecture.

• STUDY SETS found in each section are designed for students to methodically build their knowledge of the section concepts, from basic recall to increasingly complex problem solving, through reading, writing and thinking mathematically. A typical "Study Set" includes the following problem types: Vocabulary, Concepts, Notation, Guided Practice, Try It Yourself, Applications, Step-By-Step, Find It, Writing and Challenge Problems.

• DEEPEN ALGEBRAIC CONCEPT UNDERSTANDING with worked examples that use "Strategy" and "Why" explanations. Detailed author notes throughout the worked examples guide students along a step-by-step process. They are written in complete sentences to mimic what an instructor might say when he or she explains solution steps in front of the class. "Now Try" links to similar problems in the Guided Practice section of the Study Sets.

• STUDENT SUPPORT for those with difficulty reading the mathematical notation of algebra. To provide students assistance, notes such as "Read as ..." statements, appear throughout the text to explain how to read newly introduced mathematical notations.
