Reading: 1, 020,304

Analysis: Numbers have zeros at the end. No matter how many zeros there are, there are zeros at the end of any level after classification. No matter how many zeros there are, only one zero is read when needed, and how many zeros are in the middle. No matter how many zeros there are in succession, only one zero is read when needed.

Extended data

First, the multi-digit reading rules:

1, reading, starting from a high position and reading 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.

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

Don't look at the 0 at the end of each level.

Second, the rewriting of numbers.

1, rewrite a number as "ten thousand".

To rewrite a number as "ten thousand", just remove the last four zeros and add the word "ten thousand". If there are less than four zeros at the end, add a decimal point after the ten thousand digits (before the thousand digits), remove the zeros at the end and add the word "ten thousand". ?

2. Rewrite a number into "100 million".

To rewrite a number as "100 million", just remove the eight zeros at the end and add the word "100 million". ? If there are less than eight zeros at the end, add a decimal point after 100 million digits (before 10 million digits), remove the zero at the end, and then add the word "100 million". ?

3. Find out the approximate figures:

Approximate a number by omitting the mantissa after 1 100 million bits. Just remove the number after 1 100 million bits according to the rounding method, and then write the word "1100 million".
