1, the significance of mathematics: in the development of human history and social life, mathematics also plays an irreplaceable role, and it is also an indispensable basic tool for learning and studying modern science and technology.

2. Significance of natural science: The research object of natural science is the whole nature, that is, various types, states, attributes and motion forms of natural substances. The task of cognition is to reveal natural phenomena and processes, and then grasp the regularity of these phenomena and processes, so as to explain them, foresee new phenomena and processes, and open up various possible ways for rationally and purposefully applying natural laws in social practice.

Significance of social science: In the development of modern science, the new scientific and technological revolution has provided new methods and means for the study of social science, and the trend of mutual infiltration and mutual connection between social science and natural science has been strengthened day by day.

Second, the overview of the three is different:

1. Overview of mathematics: Mathematics is a discipline that studies concepts such as quantity, structure, change, space and information, and belongs to a formal science from a certain point of view.

It is a science that studies various social phenomena. For example, sociology studies human society (mainly contemporary), politics studies politics, policies and related activities, and economics studies resource allocation.

Third, the scope of the three is different:
