When reading large numbers, you should first divide the numbers into levels. Starting from the right, every four digits are level one, followed by level one, level ten thousand and level one hundred million. When reading, read one level at a time, read one trillion plus one hundred million words, and read ten thousand plus ten thousand words. Note that when reading, the 0 at the end of each stage is not read.

From right to left are: unit level (including unit, 10, 100, 1000), million level (including 10, 100, million, 10 million) and billion level (including one billion, one billion, one billion).

For example:

70006500 pronounced: 706500

9800043000 is changed to: 9.803 billion.

These levels are called level 1, level 10,000 and level 100 million respectively. ...

Second, three-digit classification?

That is, the three-digit grading method. This western classification, this classification is also an internationally accepted classification. That is, take the decimal point as the center and add a comma to every three numbers in the integer part from right to left. Such as: thousands, three zeros after the number; Millions, six zeros after the number; One billion, nine zeros after the number.
