Great people: Euclid.

 Euclid (Εὐκλείδης) was a mathematician in ancient Greece. Euclid of Alexandria was born in mid-4th century BC.

Also, he was known as the "father of geometry". Because Euclid made many things for this science.

He lived in Alexandria. Euclid created many different works about mathematics, algebra, and geometry. There is Euclidean geometry.

Now Euclid's works studied in schools and universities. 

Euclid, the Greek mathematician died in mid-3rd century BC.

Great people: Pythagoras.

Pythagoras of Samos (Πυθαγόρας ὁ Σάμιος) was known as ancient Greek philosopher and scientist. He was born in c. 570 B. C., on Samos island.

Pythagoras studied mathematics. Also, he created Pythagorean theorem. The three sides of a right triangle, the sum of the squares of the lengths of the cathetus is equal to the square of the length of the hypothenuse. They were written in Pythagorean equation:

a² + b² = c²

Also, Pythagoras of Samos visited Egypt. He found wisdom in this place. Pythagoras took part in Olympic games.

He had many important philosophical ideas. Pythagoras influenced other scientists in Ancient Greece.

Pythagoras of Samos died in c. 495 B. C.

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.
