There are two theories about the origin of numbers. First, it originated in China. According to historical records, the emperor of China had thirteen brothers, one of whom invented numbers and then invented heavenly stems and earthly branches. Invention numbers: zero, one, two, three, four, five, six, seven, eight, nine, ten, twenty, thirty, thirty, one hundred, one thousand and ten thousand.

There is also a saying that numbers originated in ancient India and were not invented by Arabs. Numbers were later mastered by Arabs for business, improved and spread to the west.
