The first is mathematics major, which belongs to a kind of neo-Confucianism. Among them, there are many specific majors in mathematics, such as mathematics, statistics, mathematics, information and computing science. High school is elementary mathematics, and there are many college mathematics subjects. Different majors learn differently, which is advanced mathematics.
Then there are engineering majors, such as machinery, civil engineering, water conservancy, computer, artificial intelligence and so on. These majors require students to study advanced mathematics, linear algebra, probability theory and mathematical statistics during their college years.
There are also majors such as finance and math teachers who should also learn the corresponding math content. Liberal arts majors basically don't need to study mathematics, and only majors related to mathematics should study mathematics.
