2. Probability: In order to prove that advanced mathematics can help pass.

3. Linear Algebra: If you study computer graphics, that is, opengl/direct3d, the spatial coordinates of the 3d model in it are represented by a matrix. If they need to be projected, superimposed and moved, matrix multiplication/transformation/transposition is needed. , so it is still very useful.

4, discrete mathematics: mainly to lay a theoretical foundation for your computer data model. It contains sets, numbers, graphs and so on. More importantly, if you want to do research in the future and study the 0-error program, that is, the program without bugs at all, you need to prove this program with its deductive theory. If you want to pass the system analyst, this is also a test.
