A documentary with subtitles. Episode 01

Acquainted with the fundamental mathematics in our lives, Marcus du Sauto explores the mathematics of Ancient Egypt, Mesopotamia and Greece.

In Egypt, he discloses the use of a decimal system based on ten fingers, while in the former Mesopotamia, two arms were counted to 60.

In Greece, he considers the contributions of some of the giants of mathematics, including Plato, Euclid, Archimedes, and Pythagoras, who are credited with starting the transformation of mathematics from a tool for counting into an analytical subject that we know today.
