The mathematics department of Southeast University is a very good major. From a popular point of view, the employment prospect after graduation is nothing more than being a teacher or doing scientific research, which is too old-fashioned and narrow. However, these are all prejudices. Graduate students who graduated from the Department of Mathematics have long been a hot potato in the fields of finance, IT and scientific research, and the employment prospects of the Department of Mathematics have bright prospects that you can't see. In the mathematics departments of universities, in addition to basic mathematics, most of them also offer applied mathematics, information and computing science, probability and statistical actuarial science, mathematics and control science. These branches of modern mathematics have gone beyond the scope of traditional mathematics and extended to all fields of society. Using mathematics as a tool to discuss and solve mathematical problems is by no means a mathematical problem. It has made great contributions to the development of human society. Of course, students of these majors are also welcome in various related fields.
