Before we go any further: Are you buying from outside Australia? We would love to ship this book to you BUT you must be studying at an Australian institution to buy this title from us at this price. Why? Because when we process your order we are required to provide to our supplier a confirmation of your student name, student ID and the institution. You really need it? We CAN still sell to overseas students however we need to advise you of the (unfortunately) higher price after you place your order. You can then decide whether you'd still like to proceed or cancel the order. That's just how it is. (sigh...) And of course, we wish you all the best with your studies : )

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, 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.

I like the layout of the textbook. I think it is very user-friendly for students. The examples are clearly worked out, the exercises are representative of the examples, and I like the different applications given in the exercise problems. Essential topics are covered - It is simple and easy for the students to read and understand - It provides a very good review of the basic background concepts that the trades and technical students are mostly needed - Colors are used for illustrations and pictures which enhances its readability - Generous with practice exercises which include both basic and applications in different areas. As a technical mathematics instructor, I have enjoyed using [this text] for the past many years. I find the text is a nearly perfect fit to my own teaching style, especially for hands-on students pursuing associate degrees and certifications in the technical fields. I also find the text effectively supports student understanding and learning. In the text, each mathematical concept is succinctly and adequately presented in basic terms making it readily understandable by students in the technical fields. Then, several examples are provided with step-by-step solutions to illustrate the use of each mathematical concept. Finally, a large number of exercises are provided to assist in developing student understanding and proficiency. I believe that most technical students find this approach to learning to be very effective.
