Ray's Practical Arithmetic

Ray's New Practical Arithmetic. 337 pages. Practical Arithmetic starts by quickly reviewing the basics of addition, subtraction, multiplication and division covered previously in Elementary Arithmetic, and then moves into a study of different types of measurement, followed by factoring, and a more involved study of fractions and percentages. After these mathematical bases have been studied and mastered, real world applications for these mathematics are introduced. These include Transactions, Commissions, Stock values and investments, Interest, Discounts, Monetary exchange, Insurance and Taxes. Practical Arithmetic then concludes by introducing basic geometry.
