1. Mathematics education plays an instrumental role in the education system 1. Mathematics itself has scientific value. The scientific value of mathematics is mainly reflected in the essential characteristics of mathematics such as accuracy, preciseness, conciseness, completeness, symmetry and unity. As a discipline, the goal of mathematics is to make chaos orderly, sublimate experience into laws, and seek a concise and unified mathematical expression of various material movements [1]. The scientific value of mathematics is mainly manifested in abstraction, logical rigor and extensive application. The abstraction of mathematics means that mathematics comes from practice, which is the abstraction of things in the real world in terms of quantitative relations and spatial forms, and has abstract characteristics in expression forms and processing methods; The rigor of mathematics means that every theorem and law in mathematics can only be established after strict proof; The wide application of mathematics means that it is the main tool to solve production and life problems because of its abstract characteristics and wide application range. Any field is inseparable from the study of mathematical phenomena and laws, especially with the rapid development of modern science and technology, the application of mathematics is more and more extensive. 2. Mathematics is a tool to learn other subjects well. An important trend in the development of modern science and technology is increasing digitalization. It requires both qualitative research and quantitative analysis, and puts forward certain mathematical relations and mathematical models to describe the motion law of the research topic [2]. Not only natural science uses mathematical language as an expression tool, but also humanities widely use mathematics as a research tool.
