## Product Description

Elementary Technical Mathematics, Tenth Edition, is intended for technical, trade, allied health, or Tech Prep programs. This book was written for students who plan to learn a technical skill, but who have minimal background in mathematics or need considerable review. To become proficient in most technical programs, students must learn basic mathematical skills. To that end, Chapters 1 through 4 cover basic arithmetic operations, fractions, decimals, percent, the metric system, and numbers as measurements. Chapters 5 through 11 present essential algebra needed in technical and trade programs. The essentials of geometry—relationships and formulas for the most common two- and three-dimensional figures—are given in detail in Chapter 12. Chapters 13 and 14 present a short but intensive study of trigonometry that includes right-triangle trigonometry as well as oblique triangles and graphing. The concepts of statistics that are most important to technical fields are discussed in Chapter 15. An introduction to binary and hexadecimal numbers is found in Chapter 16 for those who requested this material. We have written this text to match the reading level of most technical students. Visual images engage these readers and stimulate the problem solving process. We emphasize that these skills are essential for success in technical courses. The following important text features have been retained from previous editions:

• We use a large number of applications from a wide variety of technical areas, including auto/diesel mechanics, industrial and construction trades, electronics, agriculture, allied health, CAD/drafting, HVAC, manufacturing, welding, aviation, and natural resources.

• Chapter 1 reviews basic concepts in such a way that individuals, groups of students, or the entire class can easily study only those sections they need to review.

• A comprehensive introduction to basic algebra is presented for those students who need it as a prerequisite to more advanced algebra courses. However, the book has been written to allow the omission of selected sections or chapters without loss of continuity, to meet the needs of specific students.

• More than 6340 exercises assist student learning of skills and concepts.

• More than 720 detailed, well-illustrated examples, many with step-by-step comments, support student understanding of skills and concepts.

• A chapter summary with a glossary of basic terms, a chapter review, and a chapter test appear at the end of each chapter as aids for students in preparing for quizzes and exams. Each chapter test is designed to be completed by an average student in no more than approximately 50 minutes
