### Summary

Now in its seventh edition, Practical Problems in Mathematics for Electricians contains 45 instructional units featuring updated materials, examples, and expanded mathematical operations for students and trainees of the electrical trade. Coverage begins with simple addition and subtraction of whole numbers and progresses through basic algebra and trigonometry, developing readers' awareness of electrical symbols, basic circuits, component terminology, and calculator use for success on the job. Word problems designed to encourage the use of logical deduction are just one of the hallmarks of this tried and true guidebook that provides the mathematical background students need to succeed in the electrical field. Explanations at the beginning of each unit foster a better understanding of the concepts being presented; while problems related to electricity help develop an appreciation for electrical terms and practices.
