More About This Textbook
Overview
Elementary Technical Mathematics Tenth Edition was written to help students with minimal math background prepare for technical, trade, allied health, or Tech Prep programs. The authors have included countless examples and applications surrounding such fields as industrial and construction trades, electronics, agriculture, allied health, CAD/drafting, HVAC, welding, auto diesel mechanic, aviation, natural resources, and others. This edition covers basic arithmetic including the metric system and measurement, algebra, geometry, trigonometry, and statistics, all as they are related to technical and trade fields. The goal of this text is to engage students and provide them with the math background they need to succeed in future courses and careers.
Editorial Reviews
From The Critics
This textbook for trade schools reviews basic arithmetic operations, algebra, geometry, trigonometry and statistics, and features examples taken from construction, auto mechanics, electronics, agriculture, and welding. The eighth edition ads brief biographies of technical careers, and reflects the latest scientific calculators. Annotation c. Book News, Inc., Portland, OR (booknews.com)From the Publisher
"I was pleased with the exercises overall. They correspond well to the sections covered, and the balance is good." "Good graphics, good examples, good practical applications of geometry and trigonometry.""I have always been impressed with [Ewen and Nelson's] writing style. It parallels very much how I teach the course, trying to be as short and as straight to the point as possible." "My instruction time is filled with problem solving, and [the authors'] text is an extremely good fit to that teaching style." "The three greatest strengths of this text are its simple, clear plan of presenting a concept, detailing several examples, and offering many additional exercises; its many application problems from a variety of technical fields; and its chapter design with reviews, tests, and the laminated sheet of conversions."
