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, and the point in the third grid represents one hundred.

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