Economics needs to learn mathematics, but it doesn't mean how difficult economic mathematics is. If we consider econometrics, we really need a slightly higher level of mathematics. There are two methods of economic analysis, one is normative analysis, and the other is empirical analysis. Not all research and study depend on empirical analysis (empirical analysis requires a higher level of mathematics), and normative analysis can also study and study economics.

Economic mathematics is not difficult. As long as you know a few mathematical concepts, you can understand the classic theories of Confucianism, and you don't need to master higher calculation skills, mathematical thinking and a lot of calculations.

Economics is an idea, unlike a discipline, which focuses on understanding and rational application. Accurate calculation is meaningless, and good fitting is not necessarily meaningful.
