, complex function, numerical analysis, probability theory and mathematical statistics

These are all compulsory courses for mathematics majors, and both freshmen and sophomores have to learn them.

There are also numerical solutions of partial differential equations, information theory and partial differential equations in junior year.

Specialized courses in mathematics also need to learn C++, data structure and visualization.

C++ and so on.

I am also a math major. Frankly speaking, college mathematics is not as easy as high school.

You work hard. ....
