0 is an extremely important number, which was invented by ancient Indians around the 5th century. In eastern countries, mathematics is mainly based on operation (in the west, the nine numbers of Indians were written in geometry at first, and with the 0 symbol invented by Arabs, all numbers can be written. 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 centuries that zero and negative numbers were gradually recognized by westerners, which led to the rapid development of western mathematics.

Another history of 0: the discovery of 0 began in India. About after A.D., the symbol "0" has been used in the Vedas, the oldest document in India. At that time, 0 in India meant no (empty) position. Around the beginning of the 6th century, India began to use the notation of fate. At the beginning of the 7th century, the great Indian mathematician Graf Magpuda first explained that 0 of 0 is 0, and any number can be obtained by adding or subtracting 0. Unfortunately, he didn't mention the example of calculating with the symbol of life position. Some scholars believe that the concept of "0" was born and developed in India because of the philosophical thought of "absolutely nothing" in Indian Buddhism. In 733 AD, an Indian astronomer introduced this notation to Arabs during his visit to Baghdad, the capital of Iraq, because it was simple and easy to use, and soon replaced the previous Arabic numerals. This symbol was later introduced into western Europe.
