This document contains both an instructor's guide and a reference manual. It was developed as part of a cooperative venture between Industrial Technology Institute (ITI), Wayne County (Michigan) Community College, and Great Lakes Steel (GLS). The instructor's guide has four sections: math for success in electronics, student materials, electronics curricula linkage, and working with adult learners. The reference manual (the greater part of the document) contains 29 self-instructional units: rounding numbers; signed numbers; decimal numbers; fractions; converting fractions and decimal numbers; percents; converting fractions and percents; calculations with fractions, decimal numbers, and percents; scientific notation; adding and subtracting powers of 10; multiplying and dividing powers of 10; coordinates; plotting and drawing line graphs; extrapolating information from line graphs; converting metric measurements; converting English and metric measurements; converting English measurements; proportions; solving equations with whole numbers; solving equations with decimal numbers; solving equations with signed numbers; solving equations with scientific notation; solving equations with squares and square roots; solving equations with fractions; solving nonlinear equations with whole numbers; solving linear equations by transposing; solving non-linear equations by transposing; key words--electrical/electronic; and key words--math. Each unit contains the following: prerequisites, focus, job examples, key words, examples, practice problems, and answers to problems. (NLA)
