1, reading refers to expressing numbers in Chinese. Writing is writing numbers with Arabic numerals.
2. When reading, the 0 in the middle of the number should be read as zero, and the 0 at the end of the number should not be read. When writing numbers, there is no unit on any number, so write 0 on that number.
How to read numbers
Reading starts from a high position and reads one by one. 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. If there are 1 zeros in the middle of the number, or there are several zeros in succession, only one zero is read. Do not read the zeros at the end of each level.
Read the numbers from left to right according to the arrangement of numbers, for example, 3045002 is read as 3045002. This reading method is used when reading pure decimals or records. It is called simple reading method and can be used to read decimal numbers and non-decimal numbers.
How to write numbers
Generally speaking, the way to write multiple digits is to write from high to low step by step. Write 0 on any number without units.
For example, write a multi-digit number of 69 million and 80.
Write 10,000: 6900 first; Grade: 80. Then add a 0 to thousands and a 0 to hundreds, so this multi-bit should be written as 69000080.
