# Mathematical tasks and exercises.

From the experience I know that many have problems with mastering of mathematical subjects. More often it is due to lack of practice of a solution of math tasks. Therefore I have decided to create on a site the section with a collection of mathematical exercises of different complexity.

For mastering of mathematics knowledge very important not only to remember theoretical materials, but also to learn how to solve tasks. In this section the mathematical tasks of a different complexity level are collected. Solving them you can improve your mathematical skills.

## Let my present for you the collection of mathematical tasks of a different complexity level.
