Digital reading is as follows:

Every four bits are read as a whole, and the four bits as a whole are ① the lowest bit, ② 20,000 bits are the lowest bit, and ③ 300 million bits are the lowest bit.

And the zero at the end of each four-digit integer does not need to be read; If there are two non-zero numbers with two or more zeros in the middle, read only one; If all the digits in the four-digit integer are zeros, read a zero and throw the rest according to the above rules; When there is no zero between four moving people, add a zero.

For example:

304080 is pronounced as 304080.

900 100 is read as 900 100.

90000 10 12 is pronounced as 9010/2.

7000000001pronounced seven hundred and one.

1111pronounced as1011.

However, in primary school textbooks, in order to avoid more problems for primary school students because they can't understand them, the traditional reading method is that the last zero or zeros don't need to be read, and other zeros need to be read, and consecutive zeros only read one.

For example:

304080 must be read as 30 1080.

900 100 must be read as 900 100.

90050 10 12 is pronounced as 9050010/2.

3000000001pronounced 301.
