Mathematics.

Mathematics is one of the most complex and difficult sciences. It can be easy if you understand this subject.

It appeared in ancient times. Scientists studied numbers numbers and solved the problems.

Many years later people invented calculator and made mathematics easier. Math is divided into two parts: Algebra and Geometry. In the first, there are more numbers, in the second, there are more figures.

In school, children start studying this science from addition and subtraction. Then follows the multiplication table, and finally Algebra and Geometry.

If mathematics is not clear to you than it is useless to go further.

Some ancient theorems are still relevant. For example, the Pythagorean theorem or Pythagors' theorem:

a²+b²=c²

In this essay I told about one of many sciences. Next time I will write about another science and its history.
