As such, there are several claimants to the invention of the decimal system, notably the Greeks (circa 300 BC), the Chinese (100 BC), and the Indians (circa 100 AD). A Visual Tour (Video).

The Sumerians developed the earliest known writing system - a pictographic writing system known as cuneiform script, using wedge-shaped characters inscribed on baked clay tablets - and this has meant that we actually have more knowledge of ancient Sumerian and Babylonian mathematics than of early Egyptian mathematics. Babylonians later devised a sign to represent this empty place. A more accurate slogan would be "easy algebra is hard 4,000 years later with a completely different view of mathematics," but it's not quite as snappy. Our having ten of them, most of us, underlies the decimal system. Their numeral system was sexegesimal, i.e., it had a base number of 60. Babylonians used base 60 number system. The details and even the magnitudes implied (since zero was not used consistently) were idiomatic to the particular time periods, cultures, and quantities or concepts being represented. With so many factors, many fractions involving sexagesimal numbers are simplified. Their geometry extended to the calculation of the areas of rectangles, triangles and trapezoids, as well as the volumes of simple shapes such as bricks and cylinders (although not pyramids).
