The standard number 0 was invented by ancient Indians around the 5th century. They first use black dots to indicate zero, and then gradually become "0". In eastern countries, mathematics is mainly based on operation (in the west, geometry was written at the beginning, "nine numbers of Indians, plus the 0 symbol invented by Arabs, can write all the numbers).

For some reason, when the symbol 0 was first introduced to the west, it caused confusion in the west, because at that time, the west thought that all numbers were positive numbers, and the number 0 would make many formulas and logics untenable (such as dividing by 0), and even thought it was a devil's number, so it was forbidden to use it. It was not until about 15 and 16 that zero and negative numbers were gradually recognized by westerners, which led to the rapid development of western mathematics.
