PDF Early Numeration - Tally Sticks, Counting Boards, and - Sumerian The former system uses 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60 for base 60, while the latter uses 1, 2, 5, and 10 for base 10. This number has the particularly simple sexagesimal representation 1,0,0,0,0. The Babylonians, who were famous for their astronomical observations, as well as their calculations (aided by their invention of the abacus), used a sexagesimal (base-60) positional numeral system inherited from either the Sumerian or the Akkadian civilizations. Because when youre writing in base 60 without a zero, 60 looks just like 1! Thus, represents 60 plus 23, or 83.

They were perhaps the first people to assign symbols to groups of objects in an attempt to make the description of larger numbers easier. [2] Part of a series on South Mesopotamia came to be known as Babylonia as the Sumerians were eventually absorbed into the Assyro-Babylonian population. The Sumerians were among worlds first astronomers. The number 60 can be divided by 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, and 30 equal parts. Their work was widely accepted and spread throughout Eurasia.

They used this when they came up with 60 minutes in an hour and 360 degrees in a circle. [14][15], Modern uses for the sexagesimal system include measuring angles, geographic coordinates, electronic navigation, and time.[16]. Their system clearly used internal decimal to represent digits, but it was not really a mixed-radix system of bases 10 and 6, since the ten sub-base was used merely to facilitate the representation of the large set of digits needed, while the place-values in a digit string were consistently 60-based and the arithmetic needed to work with these digit strings was correspondingly sexagesimal. The most powerful driver for rigorous, fully self-consistent use of sexagesimal has always been its mathematical advantages for writing and calculating fractions. Though it is not the oldest example of writing, cuneiform script is considered a great milestone in human history.
