Is the mathematics in the next volume of senior one divided into AB edition?
Sub-AB version.

The two versions of AB mathematics course in Senior One are basically the same. In fact, it has little to do with the degree of difficulty, mainly because the research methods are different. The difference between AB version and the old version of mathematics lies in analytic geometry. Version A teaches traditional problem-solving based on proof to learn analytic geometry, while version B uses modern vector method to solve problems. Now the new textbooks, especially the 20 19 edition, are just the opposite. Version A is the vector method and version B is the traditional proof method.
