From right to left, the integer digits are: unit, ten, hundred, thousand, ten thousand, one hundred thousand, one million, ten million, one hundred million, the fifth is ten thousand, and the ninth is one hundred million. The same number, because the number of digits is different, represents different values.

"Number level" means that every four digits are divided into one level from right to left according to the counting habit of our country: unit, ten digits, hundred digits and thousand digits are one level, indicating how many ones there are; Ten thousand digits, one hundred thousand digits, one million digits and ten million digits are all ten thousand digits, indicating how many tens of thousands there are.

Reading principle:

1, numbers within four digits, read from the high places in numerical order.

2. Numbers with more than four digits should be graded according to four digits from right to left, and then read from the highest level to one billion, ten thousand and one level in turn. Read the numbers in each level and their level names.

The number in the billion-level is read according to the reading method of the single-level median, and then the word "billion" is added at the back; The numbers in the ten thousand grades should be read according to the reading method of the middle numbers at all levels, and then the word "ten thousand" should be added at the back;

3. No matter how many zeros are at the end of each level, don't read them; There is a "0" or several "0" on other numbers, all of which are read-only zeros.

Extended data:

Reading notes:

1, the 0 at the end of each stage is not read.

2. There are 1 zeros in the middle of the number, or there are several zeros in succession, and only one zero is read.

3. When reading, start from a high position and read step by step. When reading 100 million and 10 thousand levels, read according to the reading method of each level, just add a word "100 million" or "10 thousand" at the back.
