Practical, straightforward, and easy to understand, this engaging text helps students build a solid understanding of math concepts through step-by-step examples and problems drawn from a variety of occupations. Now updated with more than 1500 new exercises--including Power Up exercises to reinforce key skills over time--the Seventh Edition also features accurate, up-to-date information from the field, including expanded coverage of topics such as estimation usage, working with spreadsheets on tablets, and energy-efficient electrical applications. Content has been revised and updated to reflect current and emerging trends and technology in today’s industry, including more energy-efficient examples of electrical applications, expanded coverage of estimation usage to help students better understand whether answers are reasonable, and introductory spreadsheet material that covers working on a touchscreen tablet. The authors have revised chapter content in key areas, including consolidating many brief sections to make the text more engaging, efficient, and cohesive for today’s learners. Written in an engaging, straightforward style, the text begins with simple concepts and helps students steadily build the skills and confidence they need to solve even the most complex problems. Many exercise sets begin with a half-dozen or more Power Up exercises referencing material covered in earlier sections, helping students refresh and expand key skills as they progress through the text. Clear explanations and easy-to-follow procedural steps explain how to solve example problems, providing useful and effective guidance to help students apply what they have learned. Illustrations accompany many problems and resemble those found in technical manuals and handbooks, emphasizing the real-world relevance of mathematics concepts for professional success. Coverage of statistics ranges from introduction of basic statistical concepts to exploration of statistical graphing techniques such as bar, line, and circle graphs. The authors explain how to solve many problems using calculators and spreadsheets, providing valuable, practical instruction that students can apply on the job using common tools of the trade.
