Today's India, located in South Asia, is a unified multi-ethnic state of more than 100 ethnic groups, and it is now the second most populous country in the world. India is one of the more interesting countries. The movies are full of songs and dances, motorcycles that show off in the sky, and chic people's trailers. But in fact, India can also be said to be a country with a long culture, although it has been cut off halfway through. Indians also had a great invention that benefited the world for millennia, and this invention is now used every day.
More precisely, it was not invented by today's Indians, but by ancient Indians. Ancient India, as one of the four ancient civilizations along with China, ancient Babylon and ancient Egypt, is a melting pot of cultures. They have also left a unique style of heritage to world culture, cultural heritage is generally divided into tangible cultural heritage, that is, tangible cultural heritage, and intangible cultural heritage, that is, intangible cultural heritage.
This time, it belongs to one of the waste material cultural heritage, which is the most outstanding contribution of ancient India in the natural sciences, and the world's universal notation of Arabic numerals. Don't look at the Arabic numerals, but in fact it was invented by Indians, not Arabs. Around 500 AD, the caste system gradually arose, and mathematics in the Punjab region of India has been in a leading position. There, there was an astronomer named Ayeppiheit who had a new breakthrough in simplifying numbers.
First, Ayebichett wrote down the numbers in a grid, and if the first one had a symbol, say a dot representing 1, then the same dot in the second grid represented 10, and the dot in the third square represented 100. These symbols and representations are the earliest forms of Arabic numerals. By the 3rd century AD, there was a scientist in ancient India named Baghdad, who really invented Arabic numerals.
At that time, the oldest count was probably 3, and in order to conceive of 4, 2 and 2 had to be added up. 5, on the other hand, is represented by 2 plus 2 plus 1, and a little later, 5 and 10 begin to appear. In the eighth century, the symbol 0 began to appear, but it was called shouna. Around 700 AD, the Arabs conquered the Punjab region. They were surprised to find that the mathematics in this place was more advanced than they were, so they began to learn.
In 771, mathematicians from northern India were taken to Arabia and forced to teach mathematical symbols and systems to the natives. It is so simple and convenient, and it is easy to remember, far more than other calculation methods. Arab scholars were happy to learn, and businessmen were happy to use these numbers to do business. Subsequently, from the hands of the Arabs. The number spread in all directions, because the first people to learn about it were the Arabs. People also think that it was created by Arabs, so it is called Arabic numerals.
Actually, it should be called an Indian numeral, and by the 15th century Arabic numerals were common. At that time, the shape was not exactly the same as the modern one, and mathematicians spent a lot of effort to make them look like modern. Slowly, it became a common number in countries around the world. It was introduced to China, probably in the early 20th century. At that time, the mainland had begun to absorb and import foreign mathematics, and Arabic numerals also entered. Up to now, the promotion time has been as long as 100 years, and it has become the most commonly used number for people to learn, live and communicate. It can be said that it is used every day, which is also the greatest invention of Indians or ancient Indians.
