Why isn't Yang Chao, a graduate teacher?

Because Yang Chao is younger than other famous postgraduate teachers, not many people know him.

First, the lecturer background:

Many people only know Zhang Yu, but they don't know Yang Chao. In fact, Yang Chao is also a very powerful teacher in the field of postgraduate mathematics. He was originally a member of Changyu's team, and together with Changyu, he compiled the famous Eighteen Lectures on Advanced Mathematics. Yang Chao graduated from Tsinghua University with a master's degree and worked as a postdoctoral fellow at California State University. Engaged in postgraduate mathematics teaching for many years. He combined philosophical logic with mathematical logic, developed exclusive problem-solving ideas and original oral calculation formulas, and put forward the review concept of repeatedly training "three major calculations" in the basic stage.

Second, the lecture style:

Compared with other famous postgraduate teachers, Yang Chao is younger, but his lectures are humorous. The courses are all dry goods and there is no nonsense. The examples in the course are all novel, with moderate lecture speed and clear knowledge structure, which makes people feel very comfortable.

Third, suitable for the crowd:

Teacher Yang Chao created the formula of oral calculation, put forward the review concept of repeatedly training "three major calculations" in the basic stage, and emphasized the calculation ability in the basic stage, which is the most basic place to get high marks in mathematics for postgraduate entrance examination. If your computing ability is average, many problems you can do are always miscalculated. You might as well learn from Mr. Yang Chao, and you will certainly benefit a lot.
