Counting units are, ten, one hundred, one thousand, ten thousand, one hundred thousand, one million, ten million, one hundred million. Number, there is no 0 or 10 after the number, 1 0 after the number, 100, 2 0 or 1000, 3 0 or 10000 after the number, and 4 0 or10000 after the number.
Units, ten, hundred, thousand, ten thousand, one hundred thousand, one million, ten million and one hundred million are all units of calculation, and there is a multiple relationship between two adjacent units of calculation.

The origin of decimal system:
According to Oracle Bone Inscriptions, Shang people had learned to memorize any number within100000 with the words "1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 100, 1,000 and 10,000". Now the largest number that can be confirmed at that time is 30000. Oracle Bone Inscriptions also has the concepts of odd number, even number and multiple.
We have an idiom called "there are only a handful", which shows that the number of ancient people really cannot be separated from fingers, while the average person just has ten fingers. Therefore, the use of decimals seems to be extremely natural. But this is not entirely the case. In the ancient civilization of ancient Babylon, the 60-base system was used (this system still has traces, such as one minute =60 seconds, etc.). ), and some people use 20 decimal.
Ancient Egypt used 10 decimal system very early, but they didn't know the value system. The so-called value system is what a number stands for, depending on its position. The value system is the crystallization of thousands of years of human wisdom. Zero is the essence of the symbol of value system. But its appearance is not easy.
China is the first country to use decimal notation and realize the carry system. Our oral or written figures also abide by this principle, such as 127. At the same time, we also have the earliest understanding of 0.
Decimalization is an outstanding creation of China people, which is of great significance in the history of mathematics in the world.
Professor Needham, a famous British historian of science, once spoke highly of the notation of Shang Dynasty in China. "Without this decimal system, it is almost impossible to have our unified world now." Needham said: "Generally speaking, the number system of Shang Dynasty is more advanced and scientific than that of ancient Babylon and ancient Egypt."
