Mathematics is aimed at engineering.
Mathematics is aimed at science.
Mathematics 3 is aimed at management and economics.
The difficulty decreases in turn.
Number one is the most difficult, including advanced mathematics, probability and linear algebra. Among them, the surface differential and sequence in high numbers are all tested, which are relatively simple to learn in some schools when taking high numbers classes.
There is no probability statistics in Math II, and there is no surface differential, series, etc.
