It's not difficult. The teaching methods adopted by German universities are also different from those in China. Their teaching is more logical, their application problems are practical, and they never have tricky and unrealistic strange problems.

Specific learning contents include:

Linear algebra (solving binary to multivariate equations, inequality equations, matrix, vector calculation)

Calculus (the most basic calculus calculation, hardly involving differential equations)

Mathematics of financial economy (calculation of principal, interest and return on investment of various investments and financing)

Operational research (product optimization, queuing theory, etc. )

The above content basically involves three semesters of teaching content, and individual schools will reduce some content or compress it into two semesters according to different priorities. The direction of enterprise economic engineering, such as the Economic Engineering Society, will extend some contents, but will not feel sad about the contents of freshmen in China.

In addition, the content of mathematical statistics belongs to statistics.
