The purpose of thie Rate Training Manal is to aid those enlisted men and women who need a basic knowledge of mathematics to carry out thier Navy duties. Obviously, to serve the wide variety of ratings needing basic mathematics, the text must be general in nature and is not directed, therefore, toward any one specific rating.

The early chapters that contain basic arithmetic have been designed to give an insight into the theory behind computational processes. Even students who have mastered basic arithmetic rules should find these chapters interesting and useful.

Begiinning with chapters on number systems and positive and negative whole numbers, the course continues with discussions of fractions, decimals and percents, exponents, and radicals. Following these topics are chapters concerning common logarithms and the slide rule, algebraic fundamentals, and factoring of polynomials.

Linear equations in one variable and in two variables are discussed in separate chapters, followed by a chapter on ration, proportion, and variation. Following this are discussions of dependence, functions, and formulas; complex numbers; and quadratic equations. The topics covered in the last three chapters are plane figures, geometric constructions and solid figures, and numerical trigonometry.
