The rapid development of computer engineering in recent times has led to ail expansion of application of mathematics. Quantitative methods have been introduced into practically every sphere of human activity. The use of computers in the economy requires skilled spe­cialists who have a command of the methods of computa­tional mathematics.Computational mathematics is one of the principal disciplines necessary for the preparation of specialists for various branches of economy. By studying it students acquire theoretical knowledge and practical skill to solve various applied problems with the aid of mathemati­cal models and numerical methods that are realized on a computer.This study aid assumes that the reader is aware of the elementary concepts of higher mathematics, i.e. contin­uity, the derivative and the integral. It covers three large divisions of mathematics: “Algebraic Methods" (Ch. 2-6), “Numerical Methods of Analysis” (Ch. 1, 7, 8) and “Numerical Methods of Solving Differential Equa­tions” (Ch. 1), 10).The theoretical material presented is illustrated by nu­merous examples. Each chapter is concluded by exer­ cises for independent work.
