Arabic numerals have now become the most commonly used numbers in people's study, life and communication. In addition, around 500 AD, with the rise and development of economy, culture and Buddhism, Punjab in the northwest of Indian subcontinent has been in a leading position in mathematics. Astronomer Ayepihite made a new breakthrough in simplifying numbers: he recorded them in a grid. If there is a symbol in the first grid, such as a dot of 1, then the same dot in the second grid represents 10, and the dot in the third grid represents 100.
In this way, not only the digital symbols themselves, but also the order in which they are located is of great significance. Since then, Indian scholars have introduced the zero symbol. It can be said that these symbols and representations are the ancient ancestors of Arabic numerals today. About 700 years ago, the Arabs conquered Punjab, and they were surprised to find that the mathematics in the conquered area was more advanced than theirs. In what way can these advanced mathematics be moved to Arabia? ?
In 77 1 year, mathematicians in northern India were arrested in Baghdad, Arabia, and forced to teach local people new mathematical symbols and systems, as well as Indian calculation methods (the methods we use now). Because Indian numbers and Indian counting methods are simple and convenient, their advantages far exceed other calculation methods. Arab scholars are willing to learn this advanced knowledge, and businessmen are also willing to do business in this way, so there are no Arabic figures in the Three Kingdoms period.
