Some people describe mathematics as "gymnastics of thinking, sparks of wisdom". This shows that mathematics plays a unique and irreplaceable role in the formation of human rational thinking. As the teacher said, everyone likes math at some stage in life. Why? First, as Chen Shengshen said, "Mathematics is interesting"; Second, mathematics is useful, and life cannot be separated from mathematics. Why do you say that? Here are some simple understandings about mathematics: fun mathematics is mathematics, and mathematics itself is full of fun. As we all know, interest is the best teacher So it is natural for a person to like math. Well, take myself as an example. I first began to like math in primary school. At that time, I was fascinated by reading a children's popular science book called Interesting Mathematics at my grandmother's house. I remember there was an article in the book about Gauss summation. At that time, I felt a little shocked when I first saw it: it turns out that arithmetic can be calculated like this! It turns out that the addition of so many numbers can be calculated so easily! Since then, my enthusiasm for mathematics has increased day by day, and my grades have become better and better. However, in middle school, even in college, my enthusiasm for mathematics gradually faded, because I felt that this mathematics was becoming more and more boring, as if mathematics had become a test of some numbers. Although I am still very excited and fulfilled when I work out a math problem, I still feel bored without the "fun" fun when I was a child. So I think that the math that can make people feel fun is math. Useful mathematics is mathematics, which is an indispensable part of society. Mathematics involves all aspects of life: from the arithmetic in grocery shopping, to the train timetable, and then to the launch of the space shuttle ... which links are inseparable from mathematics. From IT, to architecture, to finance, to taxation, to design ... that industry is inseparable from mathematics. Don't say that we science and engineering students, even art students, should know the golden section. Therefore, mathematics is very useful. However, the use of mathematics is not limited to this. As the source of all human sciences, mathematics, like philosophy, can teach people many philosophies of life and different logical ways of thinking. A good mathematician must also be an extraordinary philosopher. It can be said that what mathematics teaches people to a great extent is not how to solve problems, but a belief in pursuing true knowledge. Therefore, mathematics is very useful, and useful mathematics is mathematics. My knowledge of mathematics stops here. Finally, it ends with a sentence from Xu Guangqi's translation of The Elements of Geometry: Anyone who shares this book can't get through anything. Mathematics is a lifelong subject and needs lifelong learning.
