Mathematical methodology is mainly a science that studies and discusses the development law of mathematics, the thinking method of mathematics and the law of discovery, invention and innovation in mathematics. Mathematics is a highly instrumental science, which is more abstract than other sciences. In order to develop it effectively, improve it, apply it or teach it well to students, it is required to master the development law, research methods, discoveries and inventions of this science. Therefore, math researchers, math teachers, science and technology workers, senior students and graduate students all need to know some math methodology.
