There are some things in life that you must do even if you are not interested. Don't underestimate the usefulness of mathematics. Mathematics is the necessary foundation of science and engineering. Many students immediately feel relieved when they see that college mathematics majors don't ask, because they think that mathematics is the most difficult in high school, and it depends most on application or employment prospects. But many science and engineering are based on mathematics, and science and engineering mathematics is compulsory. Many students are relieved to see that the requirements of universities for mathematics are not high, because they think that mathematics is the most difficult subject to learn in senior high school, but the most important subject is application or employment prospects. However, many science and engineering studies are based on mathematics. For example, on this basis, in order to learn solid computer engineering well, at least discrete mathematics, including set theory, graph theory, mathematical logic, linear algebra, probability statistics and mathematical analysis, should be learned. If you want to study for a Ph.D. or a master's degree in computer science, you may also need a higher mathematical foundation. In addition to professional requirements, mathematics is the crystallization of human wisdom for thousands of years. Learning mathematics can train and exercise a person's thinking ability. By learning geometry, we learn how to verify and think with deductive reasoning. By studying probability statistics, we can learn how to avoid entering a dead end of thinking and how to maximize our chances. So we must study mathematics seriously, and don't be half-hearted in choosing the method of learning mathematics. The most important thing is not how many math courses to take, but to know "why" to study, and to master a way of thinking from learning. Mathematics accumulated by human beings for thousands of years is wisdom, and learning mathematics can be trained and exercised. People's thinking ability by learning geometry, we can use deductive reasoning to verify and learn thinking methods; By learning the chance of probability and statistics, we can know how to avoid the dead end of thinking and how to make the greatest technology in front of ourselves. Therefore, we must study mathematics with heart, not perfunctory.
