## Babylonians developed The Pythagorean theorem 1,500 years before Pythagoras

The Pythagorean theorem is named after the Greek mathematician Pythagoras (*ca.* 570 BC—*ca.* 495 BC), who by tradition is credited with its proof although it is often argued that knowledge of the theorem predates him. There is evidence that Babylonian mathematicians understood the formula, although there is little surviving evidence that they used it in a mathematical framework. Also,Mesopotamian, Indian and Chinese mathematicians have all been known for independently discovering the result, some even providing proofs of special cases.
