Mathematics is an ancient and often new subject, which studies the concepts of quantity, structure, change and spatial model produced by counting, calculating, measuring and observing the shape and movement of objects. The occurrence and development of mathematics has gone through a long historical stage, which is characterized by accuracy, abstraction, rigor and extensiveness, among which abstraction is the inherent feature of mathematics, which leads to its profundity and wisdom.
Mathematics has more than one hundred branches, and its application has penetrated into all fields of natural science, technical science, social humanities and all aspects of social life. The knowledge and application of basic mathematics is an indispensable part of individual and group life.
Mathematics is applied in many different fields, including science, engineering, medicine and economics. The application of mathematics in these fields is generally called applied mathematics, which sometimes arouses new mathematical discoveries and promotes the development of new mathematical disciplines.
