How did China use decimal notation in ancient times?

Since we have written records, the notation has always followed the decimal system. Oracle Bone Inscriptions in the Shang Dynasty and Zhong Dingwen in the Western Zhou Dynasty used the words "one, two, three, four, five, six, seven, eight, nine, ten, hundred, thousand and ten thousand" to record natural numbers within 654.38+ million. This symbol has obvious value system significance.

Oracle Bone Inscriptions also has the concepts of odd number, even number and multiple.

Archaeologists have verified that in the Spring and Autumn Period and the Warring States Period in the 3rd century BC, the Chinese ancients had skillfully used the decimal notation, which was basically the same as the decimal notation commonly used in the world.

Historical facts show that China was the first country in the world to invent and use the decimal system. China used the decimal system at least 1000 years earlier than the second country in the world, ancient India.

Decimal notation includes two principles: decimal and decimal. "Decimal" refers to a complete decimal one; "Bit value" means that the same number represents different values in different positions. All numbers are represented by 10 basic symbols, which are full of ten into one.

At the same time, the same symbol has different values in different positions, so the position of the symbol is very important.

For example, three numbers "1 1", the right "1" means 1 one, the middle "1" means1ten, and the left "/kloc". This makes it easier to express and calculate extremely difficult integers.

The decimal notation is widely used. In computational mathematics, there were already four operations in Shang and Zhou Dynasties, and by the Spring and Autumn Period and the Warring States Period, the four operations of integers and fractions were quite complete.

Among them, the positive integer multiplication melody "Jiujiuge", which appeared in the Spring and Autumn Period, can be called the crystallization of the combination of advanced decimal notation and concise Chinese, which can not be produced by any other notation and language.

Since then, 99 pine has become one of the basic foundations for the popularization and development of mathematics, and it has continued to this day. It only changed from "998 1" in ancient Jiujiu songs to "22 gets 4", and now it is from "1 1 de 1" to "998 1".
