Who Discovered Zero?

Who Discovered Zero?
Who discovered zero? Discovery of Zero We can’t say for sure who discovered zero before anyone else. But the oldest records of its use are found in the ruins of Babylonia in circa 300 BC. The Babylonians were the first to invent a place hold number system, that is the use of a number to “compress” and cycle figures for easier counting and representation. While our modern system uses 10 as its place value, they used the number 60. This is the sexigesimal system used when counting minutes and seconds today. Babylonian Use of Zero The Babylonians, however, only used zero as a place holder. In other words, it was to clarify representation of numbers in written form. The Babylonians used cuneiform symbols called wedges and crescents to stand for numbers. To avoid confusion with large numbers (for example, 40 X 40 + 1 versus 40 + 1), they invented a zero symbol to mean a blank, a break. But they did not quite think of zero as a number. Zero and the Mayan Calendar At about 400 AD, the Mayans...
