Annotation

The advantages of using a mathematical apparatus in solving economic problems are indicated in

the article. The development of applications of mathematical apparatus in solving important economic

problems is analyzed. The relevance of the use of mathematical models in economic planning are justified.

The characteristic features of economic information are identified. The basic requirements for effective

analysis of economic information are grouped. The stages of processing economic information are

analyzed. Features and feasibility of using the tools of the mathematical apparatus in solving problems

are characterized. The classification of the main economic and mathematical methods used to solve

problems of varying complexity in the economy are given. Mathematical concepts underlying the solution

of applied problems of the economic direction are identified. The most frequently used functions used in

solving economic problems are characterized. The main tasks for using the objective function are

highlighted and summarized. The article summarizes the spectrum of important economic problems, the

solution of which requires the use of almost all the basic classical sections of higher mathematics,

probability theory and mathematical statistics.

Keywords: economic science, mathematical apparatus, economic problems, mathematical modeling, economic-mathematical methods, economic indicators, the general population and the sample, the function of elasticity, the production function.
