The Only Math Book You'll Ever Need will show you - step by step - how to do the math required to figure out a tip, determine your mortgage, compare investment alternatives, and much, much more. The Only Math Book You'll Ever Need takes you clearly and painlessly through a variety of everyday math challenges. Part One, The Mathematics of Personal Finance, covers earnings and taxes and explains how to determine percentage increases and evaluate such investments as time-deposit certificates, stocks and bonds, and tax-deferred annuities.

A chapter on foreign travel describes currency, temperature, metric, and electric current (voltage) conversions.

The final chapter discusses personal computers and their most useful applications in light of the average person's needs. All the chapters have undergone substantial revision and updating, and entirely new sections have been added on retirement annuities and zero-coupon bonds. You'll also find a host of new tips on how to estimate and approximate solutions to problems.
