Around A.D. 190 (about the Eastern Han Dynasty), China's figures of quantity were recorded quite completely in an ancient book called "The Heritage of Numerology". These figures include one, two, three, four, five, six, seven, eight, nine, ten, hundred, thousand, ten million, trillion, Beijing, Hong, Hong, Gou, Jian, Zheng and Zai.

Extended data:

1, quantity in unit of quantity:

Wan: stands for the fourth power of 10. Billion: stands for the eighth power of 10. Mega: stands for the power of 10/2.

Jing: It represents the power of 10/6. E: stands for 10 to the 20th power. Min: stands for the 24th power of 10.

Peng: It stands for the 28th power of 10. Ditch: stands for the 32nd power of 10. Jane: stands for 10 to the 36th power.

Positive number: represents the 40th power of 10. Load: stands for the 44th power of 10. Pole: Represents the 48th power of 10.

2. Numbers with large numbers are generally expressed by scientific notation, such as 90500000000000; We can express it by 9.05× 10 12. What does it mean? Intuitively, the decimal point after 9 in the number 9.05 is shifted to the right by 12.

3, "Five Classics Arithmetic": According to the Yellow Emperor, there are ten. There are three reasons for using it.

The tenth category is called "billion, trillion, Beijing, Yi, Yi, Gou, frugal, upright and elegant".

Third-class people are called "upper, middle and lower".

In the countdown, change from ten to ten. If you say 100 trillion,100 trillion,100 trillion, Beijing.

Those in the middle will never change it. You say 100 million, trillion is trillion, and 10 thousand is Beijing.

Count. If you count badly, change it. When you say 100 million, 100 million means 1 trillion, and 1 trillion means 1 trillion.
