(1) reads from hundreds of digits in numerical order;

(2) Write a few for hundreds, a few for ten and a few for one;

(3) If there is no one in the middle or at the end of the number, write 0 on that bit.

The same is true for four digits:

(1) reads from thousands in numerical order;

(2) Write a few on a thousand, write a few on a hundred, write a few on ten and write a few on several;

(3) If there is no one in the middle or at the end of the number, write 0 on that bit.

Extended data:

Arabic numerals consist of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 * * * 10 counting symbols. Take the position value method, the high position is on the left, the low position is on the right, and the writing is from left to right. With the help of some simple mathematical symbols (decimal point, minus sign, percent sign, etc. ), this system can clearly represent all rational numbers. In order to express extremely large or extremely small numbers, people have created scientific notation on the basis of Arabic numerals.

Arabic numeral writing rules

(1) The "0" before the decimal point of pure decimal cannot be omitted. Whether it is narrative or chart, the "0" before the decimal point of pure decimal cannot be omitted, and numbers in the formats of ".27, .39" cannot appear.

(2) Arabic numerals cannot be used together with chinese numerals, except "Wan", "One" and Chinese symbols with the prefix "SI". For example,13 million can be rewritten as13 million, but it cannot be written as13 million.

(3) Numbers with four digits or more should be written by three-digit segmentation method.
