The origin of Indian mathematics, like other ancient nations, is based on the actual needs of production, but it has been fully developed under the influence of Brahman rituals. Coupled with the exchange of Buddhism and trade, Indian mathematics and China mathematics are advancing in mutual integration and mutual promotion. In a certain period or a certain field of mathematics, there is indeed an advanced side. For example, it is an Indian invention to use nine symbols and a circle to represent all numbers (decimal and Arabic numerals). Another example: 85×85=? Can you work out the answer at once? After learning the calculation method of Indian Vedic mathematics, you can give the answer in 2 seconds. However, since modern times, China people have always been far ahead in the international Olympic mathematics competition. The multiplication formula introduced by the British from China has never worked, and many China mathematics teachers have to be hired to improve the mathematics level of British students. It can be seen that the mathematics ability of China people is still the best in the world!
