Very big! A few years ago, the state set up the highest scientific prize of 5 million, among which mathematician Wang Xuan won the prize in the first year. Mathematicians like Chen Shengshen and Qiu Chengtong are outstanding, and their contributions are self-evident. And science and technology are stronger, and mathematics is more important. A nation should innovate and face the world rationally. These are also the ways in which mathematics cultivates people's thinking. Mathematical thinking makes people rational, not fragile and powerful. Moreover, the figures in mathematics are so beautiful, the probability is very practical, and equation analysis is also an engineering application. In short, a person's life can't be separated from mathematics, and of course a country can't be separated from mathematics!
