Painless algebra

Algebra (other title)

Long, Lynette. (Author). Morehouse, Hank (illustrator.).

Summary: For students who are intimidated by all forms of math, here is a set of easy steps that lead to an understanding of elementary algebra. The author defines all terms, points out potential pitfalls in algebraic calculation, and makes problem solving a fun activity. New in this edition are painless approaches to understanding and graphing linear equations, solving systems of linear inequalities, and graphing quadratic equations. Barron's popular Painless Series of study guides for middle school and high school students offer a lighthearted, often humorous approach to their subjects, transforming details that might once have seemed boring or difficult into a series of interesting and mentally challenging ideas. Most titles in the series feature many fun-to-solve "Brain Tickler" problems with answers at the end of each chapter.
