1, basic mathematics
Basic mathematics is also called pure mathematics, that is, according to the inherent needs of mathematics or possible future applications, studying the inherent laws of mathematical structure itself has no direct connection with seeking common ground while reserving differences and solving practical problems in other disciplines, but only studies the quantitative relationship and spatial form of things in pure form.
2. Computational mathematics
Computational mathematics is a new discipline that has developed rapidly with the appearance of computers, involving computational physics, computational chemistry, computational mechanics, computational materials science, environmental science, earth science, finance and insurance and many other interdisciplinary subjects.
3. Applied Mathematics
Applied mathematics includes two parts, one is related to application, and the other is the application of mathematics, that is, using mathematics as a tool to explore and solve problems in science, engineering and sociology.
