Babylone. Babylonian Pythagoras - MacTutor History of Mathematics. Pythagoras's theorem in Babylonian mathematics In this article we examine four Babylonian tablets which all have some connection with Pythagoras's theorem.

Certainly the Babylonians were familiar with Pythagoras's theorem. A translation of a Babylonian tablet which is preserved in the British museum goes as follows:- 4 is the length and 5 the diagonal. What is the breadth ? All the tablets we wish to consider in detail come from roughly the same period, namely that of the Old Babylonian Empire which flourished in Mesopotamia between 1900 BC and 1600 BC. Here is a map of the region where the Babylonian civilisation flourished. Babylonian numerals - MacTutor History of Mathematics. The Babylonian civilisation in Mesopotamia replaced the Sumerian civilisation and the Akkadian civilisation.

We give a little historical background to these events in our article Babylonian mathematics. Certainly in terms of their number system the Babylonians inherited ideas from the Sumerians and from the Akkadians. From the number systems of these earlier peoples came the base of 60, that is the sexagesimal system. Yet neither the Sumerian nor the Akkadian system was a positional system and this advance by the Babylonians was undoubtedly their greatest achievement in terms of developing the number system. Some would argue that it was their biggest achievement in mathematics. Often when told that the Babylonian number system was base 60 people's first reaction is: what a lot of special number symbols they must have had to learn. Now although the Babylonian system was a positional base 60 system, it had some vestiges of a base 10 system within it.

Which, in decimal notation is 424000. Babylonian mathematics - MacTutor History of Mathematics. The Babylonians lived in Mesopotamia, a fertile plain between the Tigris and Euphrates rivers.
