Beginning Algebra-Mathematics

A text which students can actually READ and use to learn beginning algebra — and which instructors can use as a genuinely supportive framework from which to teach algebra — Beginning Algebra with Applications features an easy-to-read presentation, an emphasis on problem-solving skills, a wealth of well-chosen, illustrative examples, and uniquely structured problem sets.

places a greater emphasis on problem solving and mathematical modeling of real-world applications.

• includes “You Decide” problems at the end of each chapter. These open-ended, extended real-world applications help students develop critical thinking and writing skills. Because these problems have no one correct answer, students are able to hone their problem-solving and decision-making skills by deciding upon and then supporting their answer with specific evidence. (pp. 109)
• contains more word problems throughout. (pp. 203)
• revises applications to reflect a more current, realistic context.
begins each chapter with “Connections” — an introductory paragraph which puts the upcoming material in context with other chapters, other disciplines, math history and the real world. (pp. 233)
features problem sets uniquely organized into discrete levels of understanding:
• Warm-Ups — carefully graded and keyed specifically to examples in the section. (pp. 242)
• Practice — mixed, and not referenced to any examples. (pp. 243)
• Challenge — probe natural extensions of the topics. (pp. 243)
• In Your Own Words — test conceptual understanding by requiring a written answer. (pp. 243)
highlights “key” problems in red throughout the exercise sets. These are considered to be essential problems which, if assigned, will cover all the section learning objectives. They can be used in class examples, problem assignments, or for review. Answers are provided at the end of the text. (pp. 250)
features “Let's Not Forget” problems at the end of every chapter review problem set. These exercises are cumulative and require students to review topics covered in previous sections and chapters. (pp. 326)
provides “Be Careful” annotations in the margins — to prominently point out common student errors. (pp. 314)
concludes chapters with a glossary, review of key concepts, and “Check Ups” — worked examples stated as problems with specific references. (pp. 323, 324)
