After studying for several years, I have never had a good understanding of mathematics. Now, when I face so many problems such as mechanics, physics, chemistry and structure, I think of the magic of mathematics, which can involve all aspects of our lives! 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: "If we want to know nature dialectically and materialistically, we must master mathematics." Bacon, a famous British philosopher, said: "Mathematics is the key to science. With the development of science and technology, people are more and more deeply aware 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 directly or indirectly experienced a mathematical process. 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. Every science has its history of development. As a historical science, it is both historic and realistic. Its reality is first manifested in the continuity of scientific concepts and methods. Today's scientific research is to some extent the deepening and development of scientific tradition in history, or the solution of scientific problems in history, so we can't separate the relationship between scientific reality and scientific history. Mathematical science has a long history. Compared with natural science, mathematics is an accumulative science, and its concepts and methods are more continuous. M Klein, an American mathematical historian, once said: "The general characteristics of an era are closely related to the mathematical activities of this era to a great extent. Mathematics has widely influenced human life and thought, and is the main force to form modern culture. Therefore, the history of mathematics reflects the history of human culture from one side and is the most important part of the history of human civilization. Many historians understand the characteristics and value orientation of other major ancient cultures through the mirror of mathematics. The history of science is an interdisciplinary subject of arts and sciences. Judging from today's educational situation, the gap between arts and sciences leads to the fact that the talents trained by our education are increasingly unable to adapt to today's modern society with high penetration of natural science and social science. It is precisely because of the interdisciplinary nature of the history of science that it can show the role of communicating arts and sciences. Through the study of the history of mathematics, students in the department of mathematics can receive the training of mathematics major and get the cultivation of humanistic quality, while students in liberal arts or other majors can learn the general situation of mathematics and get the cultivation of mathematics and physics through the study of the history of mathematics. The achievements and moral character of mathematicians in history will also play a very important role in the personality cultivation of teenagers. The history of mathematics can help students understand the brilliant achievements of ancient mathematics, the development status of modern mathematics, the research status of modern mathematics in China and the gap with developed countries, thus stimulating students' patriotic enthusiasm and revitalizing national science. Mathematics is not only a method, an art or a language, but also a rich knowledge system, which is very useful to natural scientists, social scientists, philosophers, logicians and artists and influences the theories of politicians and theologians. In a word, mathematics and the history of mathematics play a very important role in both its historical and practical significance, which is worth studying and mastering.
