Arabic numerals were 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 were introduced into China around 13 ~ 14 century. Because there was a number called "abacus" in ancient China, which was easy to write, Arabic numerals were not popularized and used in China at that time. At the beginning of the 20th century, with the absorption and introduction of foreign mathematical achievements, Arabic numerals began to be used slowly in China, and it was only 100 years since it was popularized in China. Arabic numerals have become the most commonly used numbers in people's study, life and communication.
