More than 3,000 years ago, ancient Egypt used special symbols to indicate the fraction of a molecule as 1 in order to represent an undivided number. China had scores more than two thousand years ago, but the forms of scores in Qin and Han Dynasties were different. There is a fractional representation system in India similar to that in China. Later, Arabs invented the fractional line, and today's fractional expression also came from it.

Extended data:

The earliest fraction was the reciprocal of an integer: an ancient symbol representing one-half, one-third, one-quarter and so on. Egyptians used the Egyptian score of 1000 BC. About 4000 years ago, Egyptians separated with slightly different scores. They use the least common multiple and unit fraction. Their method gives the same answer as the modern method. Egyptians also have different representatives of Akhmim sawdust and the second generation of mathematical papyrus.

The modern score called bhinnarasi originated in India. They put the numerator in the denominator, but there is no stripe between them, forming a fraction. In Sanskrit literature, fractions are always expressed as addition and subtraction of integers. Integer is written in one line, and its score is written in the next line of two lines. What if the score is in a small circle? 0was or cross? +was tag, which is subtracted from the integer; If such a sign does not appear, it is understood as adding.
