Mathematics reading and writing in grade one.
Reading and writing numbers start from the top left and start from the right. The first digit is one, the second digit is ten, and the third digit is one hundred. Note: Decimals are not included.

Read from high to low, step by step, the zero at the end of each stage is not read, and the remaining digits only read one zero for several consecutive zeros; How to write integers: write from high to low step by step. If there is no unit on any number, write 0 on that number.

For example, 1203.4 should be read as: 1203.4, that is, read from the highest bit 1, write from the highest bit 1, and write from high to low.

Reading is to express numbers in words, for example: 1203.4 reading: 1203.4 writing numbers is to express a number with numbers and symbols. Such as: 1 12.5

Extended data

Reading rules

1. Read in numerical order from the highest.

2. There are thousands of people studying and hundreds of people studying.

There are dozens of students enrolled in ten schools and dozens of students enrolled in one school.

3. There is a zero or several zeros in the middle, and the zero is read-only;

No matter how many zeros there are at the end, don't read them.

Rules for writing numbers

1. Write in numerical order from the top.

2. Write thousands, hundreds, tens and single digits.

If there is no one in the middle or at the end, write 0 on that bit.
