Lesson 4: DEFINITION & HISTORY OF GEOMETRY
The Babylonians replaced the older (4000 BC – 2000 BC) Sumerian civilization around 2000 BC. The Sumerians had already developed writing (cuniform on clay tablets) and arithmetic (using a base 60 number system). The Babylonians adopted both of these. But, Babylonian math went beyond arithmetic, and devloped basic ideas in number theory, algebra, and geometry. The problems they wanted to solve usually involved construction and land estimation, such as areas and volumes of rectangular objects. Some of their methods were rules that solved specialized quadratic, and even some cubic, equations.
