ELEMENTARY ALGEBRA offers a practical approach to the study of beginning algebra concepts, consistent with the needs of today's student. The authors place special emphasis on the worked examples in each section, treating them as the primary means of instruction, since students rely so heavily on examples to complete assignments. Many of the applications (both within the examples and exercises) are also uniquely designed so that students have an experience that is more true to life--students must read information as it appears in headline news sources and extract only the relevant information needed to solve a stated problem. This promotes the text's focus on developing better study habits, problem solving and critical thinking skills along with orienting students to think and reason mathematically. Through Elementary Algebra, students will not only be better prepared for future math courses, they will be better prepared to solve problems and answer questions they encounter in their own lives. Available with InfoTrac® Student Collections http://gocengage.com/infotrac.
- Real Sources. Among the application problems appearing in this textbook are specially developed exercises and examples that reference information taken directly from news articles, research studies, and other fact-based sources. Many of these applications are set up in two parts with a problem statement given first followed by an excerpt. Since the question appears first and then the information needed to answer the question follows, students experience problem solving in a more true-to-life way. Though similar in length to texts or tweets, the authentic excerpts often contain more information than is needed to solve the applications. Students will need to think critically to select the relevant information and in doing so, practice the skills needed to solve problems outside of the classroom.
- Checking for Accuracy and Reasonableness. To be successful in mathematics and other disciplines, an important skill for students to develop is checking their work for reasonability and accuracy. The explanations of reasonability in examples of the Five Steps and the checking of solutions in many of the worked examples provide a model for students learning to reflect on their own work. Being able to justify an answer helps students develop confidence and self-sufficiency. For those who wish to explore checking answers for reasonableness in more depth, an appendix is included in the back of the book.
- Using Technology. For instructors who wish to integrate calculator technology, optional scientific and graphing calculator instruction is provided at the end of selected sections, where appropriate. The instruction that appears within the Using Technology boxes includes examples with keystrokes, screen shots, and Practice Problems. Follow-up Technology exercises appear at the end of section-ending exercises for continued practice.
- End-of-Chapter Study Plan and Review Exercises. This tool offers students an effective and efficient way to prepare for quizzes or exams. The Study Plan, appearing at the end of each chapter, includes study tables for each section that will help students get organized as they prepare for a test or quiz. Each table contains a set of Can I? questions, based on the section objectives, for self-reflection. Can I? questions are tied to one or more Review Exercises that students can use to test themselves. Examples and/or Practice Problems are also linked to each question should students need reference for review.
- Five Steps for Problem Solving. Based on the work of George Polya, the Five Steps provide a framework for jump starting and organizing student problem solving. Step-by step worked examples throughout the textbook support students as they learn to solve a wide range of applications.
- Unique Online Homework Problems. Consistent with the authors’ approach, unique features and problem types from the text have been integrated into the Enhanced WebAssign® online homework course that accompanies the text including the 5-Steps framework, Success in College Math, Find the Mistake and Solving Equation Exercises with Checks. Online assignments can be built by selecting from thousands of text-specific problems or can be supplemented with Extra Problems have been carefully selected from other Cengage Learning developmental mathematics series. Enhanced WebAssign engages students with immediate feedback, rich tutorial content and interactive, fully customizable eBooks (YouBook) helping students to develop a deeper conceptual understanding of their subject matter.

- Success in College Mathematics. To help students transition to college-level mathematics, Success in College Mathematics appear at the beginning of each chapter and address topics such as personal responsibility, study skills, and time management. Follow-up exercises appear at the end of each section to help students reflect on their own attitudes and habits and how they can improve their performance. This feature also helps instructors identify issues outside of mathematics that may affect student success and retention.
- Examples with Step-by-step Explanation. Each step of the worked examples is accompanied by an annotation that explains how the solution progresses, from the first line to the final answer. Color-coding and boldface are also used to help students easily identify the operation that occurs in each step, enabling the text to act as tutor when students are not in the classroom.
- Side-by-side Examples. To help students apply their knowledge of arithmetic to algebra, some of the worked examples are set up side-by -side with shared annotations. In this format, students can more readily see how certain principles and procedures are used repeatedly in both arithmetic and algebra.
- Practice Problems. Following a set of worked examples in each section are a set of Practice Problems that mirror the examples. Students can use the Practice Problems to check their understanding of the concepts or skills presented.
- Problem Solving: Practice and Review. Beginning in Ch. 2, each section-ending exercise set includes a short set of applications-based exercises called Problem-Solving: Practice and Review. Because these problems do not involve the concepts or skills taught in the section, students need to think critically about the information and relationships in the problem. Even in sections that have few or no applications, students can continue to practice their problem-solving skills by completing one or more of these exercises.
- Find the Mistake. The section-ending exercise sets include Find the Mistake exercises. Each exercise is a problem and a step-by-step solution which includes one mistake. Students are asked to identify the error and then rework the problem correctly. These exercises help students learn how to find errors in their own work which improves student persistence and self-sufficiency.
- Learning the Language of Math. Vocabulary matching exercises that appear before the section-ending exercises help students improve their knowledge of vocabulary and notation.

"The text effectively covers the skills traditionally found in a developmental algebra book with the added emphasis on problem solving. I appreciate the inclusion of graphing calculator aids without requiring them. The writing style and level are appropriate for a developmental math student. This text fits my own philosophy of developmental mathematics education quite well."
"I love [the Find the Mistake end-of-section questions]. I have used such in my own classes many times. They are surprisingly hard to write and [I] would definitely assign them to my students."
"The authors' approach is definitely obvious in the text. Problem solving is clearly a focus, and the variety of applications is immediately evident. The fact that the applications include excerpts from current research and reports provides the real-life context that the author's desire as well as increasing student interest and the number of problems with extraneous information will force students to read carefully for important information. These problems do not appear periodically; they are intentional and consistent. The Problem Solving Practice and Review (Mixed Applications) demonstrates the authors' desire to provide opportunities for students to think about problems, not merely follow a formulaic problem type. The extra support for students is also carried out through the entire text. The examples continue to show all steps in later chapters as thoroughly as they do in the early ones."
