# Propaedeutics of Solving Extreme Problems in the School Course of Mathematics

176

## Abstract

This article discusses the propaedeutics of solving extreme problems. As is known, such tasks play an important role in various fields of science and technology. They often reduce many of the problems that arise in the economy, industry and agriculture. As a rule, the solution of these problems requires the use of a fairly complex mathematical apparatus studied in higher education. However, many problems on the maximum and minimum can be solved by elementary means without the use of higher mathematics. The solution of such problems is very useful for students as propaedeutics of the relevant subjects.
