Multi-digit reading method in fourth grade mathematics
The reading method of mathematics multi-digit in grade four is as follows:

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 10,000-level should be read according to the reading method of the first-level median, and then the word "10,000" 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.

Summary points:

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.

Four-digit grading method:

In China, it is customary to classify multiple digits with four digits, that is, starting from one digit, every four digits are regarded as the first level. Four, ten, one hundred, one thousand, one level; Ten thousand, one hundred thousand, one million and ten million are called ten thousand levels; Billions, billions, billions, billions is called billions. Level 1, level 10,000, level 100 million and so on. It is called several levels.
