Intended for introductory courses in basic mathematics, this comprehensive text teaches the skills necessary for practical work involving architectural and mechanical drafting, electronics, welding, air conditioning, aviation, and automotive mechanics, and machining and construction. The authors have carefully organized the material to provide flexibility: the text can be used in a lecture class, in a laboratory setting, or for self-paced instruction. Each chapter is divided into frames that present the individual concepts on which the major concepts are based. To ensure student comprehension, each concept is first explained and then illustrated with an example. Questions about the material test students' understanding of the concepts, and the answers are found on the right side of each page. Exercise sets throughout the chapters and self tests at the end of each chapter provide further opportunity for students to master the material. In all, the text presents more than 3,000 problems and exercises.
