Lucy: Thousands of units are commonly used in English, such as thousands of units, millions of units and billions of units, with three spaces between them. There is no such unit as China Wanhe and Million Units.

These figures are as follows:

1'000, 1'000'000, 1'000'000'000。

One million is Qian Qian, and one billion is Qian Qian's 1,000, just as China people say that 100 million is absolute.

Three-position segmentation method:

Digital segmentation usually adopts three-digit segmentation method, starting from unit teaching, every three digits are divided into one paragraph. Vouchers, account pages and statements used in accounting are also printed according to the above practice.

Accountants are always playing word teaching games. For digital segmentation, it is generally considered that it is only for the convenience of counting and explanation, but it does not think deeply about its problems.

However, in recent years, many people have questioned this segmentation method, thinking that the three-digit segmentation method is out of touch with the rules on tender classification in mathematics and filial piety, and advocating the four-digit segmentation method, so that people can read and read numbers and improve work efficiency.

This is becoming more and more reasonable. The four-division method was first seen in the mathematical sperm pot translated by He Guozong and others in the Qing Dynasty, and it was worn and used earlier. The trisection was adopted in the late 1930s.

In primary school mathematics textbooks, numbers are divided into "unit level", "million level" and "billion level". Unit, 10, 100 and 1000 belong to "unit level", and 10,000, 100,000, 1 million and 10 million belong to "10,000 level". One billion, one billion, one billion and one billion belong to the "billion level".

According to this rule, when reading a number with only one level, the names of the effective digits can be read from high to low, such as 5, 7, 8 and 6 in the number 5786, which are thousands, hundreds, tens and digits in the level respectively, and can be read as "5786 digits".

To read a 10,000-digit word, you can first write this 10,000-digit number into a 10,000-digit number, and then read a word "10,000" according to the ten-digit reading method, for example, 57,860,000, where 5, 7, 8 and 6 are 10 million, 1 million, 100,000 and 10,000 digits respectively.

When reading, you can first read "5786" with tens of thousands of digits as "5786" and then read another word "10,000", which is "57.86 million".

Similarly, "578 600 000 0000" containing hundreds of millions of digits can be read as "57.86 billion". If tens of thousands of digits and unit digits contain numbers other than zero, you can still read tens of thousands of series and units immediately after reading one billion series.
