Quick Navigation

Overview

ELEMENTARY TECHNICAL MATHEMATICS helps students with minimal math background successfully prepare for technical, trade, allied health or tech prep programs. Author Dale Ewen focuses on fundamental concepts in basic arithmetic: the metric system and measurement, algebra, geometry, trigonometry and statistics. Thousands of examples, exercises and applications cover such fields as industrial and construction trades, electronics, agriculture/horticulture, allied health, CAD/drafting, HVAC, welding, auto/diesel service, aviation, natural resources, culinary arts and business/personal finance--to engage students and provide them with the math background they need to succeed in future courses and careers.

Dale Ewen

Dale Ewen, Executive Vice President of Parkland College, Illinois, (1999-present), graduated from the University of Illinois with a B.S. in 1963 and an M. Ed. in 1966. He has been the recipient of several AMATYC (American Mathematical Association of Two-Year Colleges) awards and served as the organization's President (1989-91). Dale continues to write a number of technical mathematic textbooks.

What's New

{{collapseContainerClosed['whats-new'] ? 'Show More' : 'Show Less'}}
  • Applications in the areas of industrial and construction trades, electronics and CAD/drafting were reviewed and updated with the assistance of experts working in these areas. All other areas were reviewed and updated with current information and data by the author.
  • Major effort was made to streamline the text by creating a more space efficient page design, reviewing art size and placement, moving Group Activities at the end of each chapter to the Instructor Companion Website, and removing outdated material.
  • After thorough review, this text provides better rationale for measurement accuracy and precision and calculations with measurements, compares single vs. multiple measurements, and introduces the concept of random and systematic errors.

Features

{{collapseContainerClosed['features'] ? 'Show More' : 'Show Less'}}
  • Signed number drills exercises assist students in learning addition, subtraction and multiplication on signed numbers.
  • Cumulative reviews at the end of every even-numbered chapter enable students to review and prepare for comprehensive exams.
  • Many applications from a wide variety of technical areas are noted by marginal icons, including industrial and construction trades, electronics, agriculture/horticulture, allied health, CAD/drafting, HVAC, welding, auto/diesel service, aviation, natural resources, culinary arts and business/personal finance engage students and illustrate the relevance of what they're learning. Marginal icons call attention to the applications, making it easier for instructors and students to find and explore them.
  • Each chapter opener presents basic information about a technical career underscoring the connection of the math to real life.
  • The inside covers contain useful, frequently referenced information--such as metric system prefixes, English weights and measures, metric and English conversion and formulas from geometry.
  • Chapter 1 reviews basic concepts in such a way that students or the entire class can easily study only those sections they need to review.
  • The use of a scientific calculator has been integrated in an easy-to-use format throughout the text to reflect its nearly universal use in technical classes and on the job.
