"Simple" math-like fractions, decimals, and percentages-can prove maddeningly difficult. Math Essentials helps readers learn to solve these everyday, yet complex math problems and meet the demands of both the workplace and the marketplace. A handy review of the basics, this book focuses on the practical and daily uses of math, such as calculating how much money a low-interest loan will save, determining the effect of mortgage rate changes, computing profits on a stock transaction, and figuring out how much of that salary increase will actually end up in a paycheck.
