Arabic numerals consist of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 * * * 10 counting symbols. Arabic numerals were first invented by ancient Indians, then spread to Europe by Arabs, and then modernized by Europeans. People think they are the inventions of Arabs, so people call them "Arabic numerals".

origin

Around 500 A.D., with the rise and development of economy and caste system, Punjab in the northwest of Indian subcontinent has been in a leading position in mathematics. Astronomer Ayepihite made a new breakthrough in simplifying numbers: he recorded the numbers with a grid. If there is a symbol in the first grid, such as a point representing 1, then the same point in the second grid represents ten.

The point in the third column represents 100. In this way, not only the digital symbols themselves, but also their position order is of great significance. Later, Indian scholars introduced the symbol zero. It can be said that these symbols and representations are the old ancestors of Arabic numerals.
