Mathematics is a science that studies the relationship between spatial form and quantity in the real world, including arithmetic, algebra, geometry, trigonometry, calculus and so on. Mathematics is also an important basic theoretical course for students majoring in economics and science and engineering in colleges and universities. Mathematics not only studies the quantitative relations and spatial forms in the real world, but also studies various abstract pattern structures of "number" and "shape". Engels said: "We should understand nature dialectically and materialistically. You must be proficient in mathematics. " Bacon, a famous British philosopher, said, "Mathematics is the key to science. With the development of science and technology, people realize more and more deeply that it is difficult to create contemporary scientific achievements without mathematics. The faster and higher the development of science and technology, the greater the demand for mathematics.
Nowadays, with the rapid development of computer technology, the mathematical trend of natural science and the quantitative requirement of social science, many disciplines have experienced a mathematical process directly or indirectly sooner or later. We can see a powerful mathematical process in basic science and engineering construction research, management function and military command, economic planning and even human thinking.
