The first semester of fractional analytic geometry is 3.2 1, then the mathematical models of complex variable ordinary differential in modern algebra are 3.2/,then the numerical calculation, probability theory and mathematical statistics are 2 semesters, then the random process is 3.2/,then the real variable is 3.2/,and finally the functional partial differential is1. At present, the estimation of topology and differential geometry is also relatively backward.

In a word, mathematical analysis and advanced algebra are the most basic. Complex change is earlier than real change, and simpler than real change. It is said that ordinary differential is earlier than partial differential functional, but I haven't learned it yet.

In higher algebra, it is more important to analyze the number system of probability theory of complex variable and real variable mathematically, while others are uncertain.

In other words, this process is studied by undergraduate mathematics department, and the proportion of people studying this process is not large. If you are an engineering major, it seems ok to learn calculus probability theory of high-number linear algebra, but the economics class is simpler, so I won't say it.
