Nowadays, advanced mathematics generally refers to a course for non-mathematics majors in colleges and universities. The teaching content of this course will vary with different majors. For example, the contents of advanced mathematics courses for management majors such as business administration will be less (and less difficult) than those for science and engineering majors.

Discrete Mathematics is a mathematics course based on advanced mathematics for some professional students in colleges and universities. It only studies the change behavior of the function when the independent variable changes discretely (that is, jumps) rather than continuously.
