At present, mathematics education generally imitates the way and difficulty of Olympic Mathematics, which lacks practicality and creates little academic value. It is important to do more exercises and accumulate problem-solving skills.

In the process of learning advanced mathematics, it is extremely normal to encounter things that you don't understand. At this time, what you need is to check some basic elementary mathematics knowledge (pay attention to systematic mastery) and go back to your own research (you must work hard and have perseverance. For example, it took me 1 months to understand Taylor's formula.

Higher mathematics studies nonhomogeneous variables. Advanced mathematics (the general name of several courses) is an important basic subject in science and engineering colleges, and it is also a compulsory mathematics course for non-mathematics majors in science and engineering, as well as a compulsory course for other majors.

The computational aspect of mathematics. Even occupies a dominant position in elementary mathematics. Its position in higher mathematics is also obvious. In addition to many theoretical subjects, advanced mathematics also has a large number of computational subjects, such as differential equations, computational mathematics, statistics and so on. With highly abstract theoretical equipment, it is possible for these disciplines to deal with complex computing problems in modern science and technology.
