The meaning of the score:

A fraction is the ratio of an integer a to a positive integer b that is not equal to an integer. The essence of a fraction is a fraction indicating that one number is another number, or the ratio of one event to all events. Divide the unit "1" into several parts on average, and the number representing such a part or parts is called a fraction.

The nature of the score:

Fractions are either finite decimals or infinite cyclic decimals, and infinite acyclic decimals like π cannot be replaced by fractions. When the numerator and denominator are multiplied or divided by the same number (except 0), the fractional value will not change. Therefore, each score has an infinite number of equal parts. Using this property, we can be on and off.

The result of exponentiation of a fraction cannot be an integer. If it is the simplest fraction before the operation, the result is the simplest.

Score history:

The earliest fraction was the reciprocal of an integer: an ancient symbol representing one-half, one-third, one-quarter and so on. Egyptians use the Egyptian score c? 1000? 200 BC. About 4000 years ago, the Egyptians were separated by 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 representations of Akhmim wood chips and the second generation of mathematical papyrus.

The Greeks used unit fractions and (post) continuous fractions. Greek philosopher Pythagoras (about 530? Bc) Followers found that two square roots cannot be expressed as part of an integer. Among 150 Indians in India, Jain mathematicians wrote "Sthananga? Buddhist scriptures, including number theory, arithmetic operation and operation.
