Mathematics describes the relationship between the number and position of objects in reality, and then gradually develops to describe the relationship between some phenomena. In other words, mathematics actually comes from life and then serves reality, but this kind of service is gradually diluted by people because it is too difficult. But it is undeniable that mathematics is indeed a more useful subject, such as statistics, modern sociology, and even good at statistics. You must be a high-quality talent. It is only possible that there is some deviation in our education, or we can't find a way to "carry forward" mathematics. On the other hand, mathematics is a discipline that exercises people's thinking. For example, what should I do if I encounter problems in real life? Mathematics is to teach you how to analyze problems and find solutions when you encounter problems (analysis, overall planning, algorithm and so on are all related to this), which is one of the reasons why mathematics is listed as one of the three major disciplines. It's just that our education seems to be getting farther and farther away from this goal, or our usual performance in this respect is not ideal. In fact, we often deal with mathematics at ordinary times. For example, if someone asks you the way, how do you answer? This is a coordinate problem in mathematics, but we unconsciously associate this problem with mathematics. Of course, the coordinate system you set up in your mind is different, and the way you speak it is different. If you set up a rectangular coordinate system, you would say how far to the left, how far to the right, and how far up. If you set up a cylindrical coordinate system, you may say that you have gone up as far as you turned in which direction and how far you went. Longitude and latitude.
