Arabic numerals are now commonly used in the world. It was first invented by ancient Indians, then spread to Europe by Arabs, and then modernized by Europeans. Because of the spread of Arabs, it has become a key node in the international use of such numbers, so people call it "Arabic numerals".

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 numerals can be easily changed by changing the position of the decimal point. Therefore, in special occasions (such as banks), capital Chinese characters cannot be completely replaced.
