Who is the early forerunner of them mathematician of the world

The early forerunner of the mathematicians of the world is considered to be Thales of Miletus, who lived around the 6th century BCE. He is often credited as the first mathematician and is known for his contributions to geometry, particularly for his theorem on the properties of triangles. Thales played a significant role in laying the foundation for the development of mathematics as a field of study.

The ancient Greek mathematician and philosopher Pythagoras is often considered one of the early forerunners of mathematics. He lived during the 6th century BCE and is best known for the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. Pythagoras and his followers made significant contributions to various fields, including geometry, arithmetic, and number theory, laying the foundation for future advancements in mathematics.
