1. Generally speaking, version A can be said to be a knowledge combing version and a basic version. Version B can be said to be an improved version, with many topics and greater difficulty than version A, mainly explaining the knowledge points of version A, and the topics of version B are mainly college entrance examination questions and simulation questions in this province.
2. Implement different regions: Version A and Version B are divided into "regions", that is, one version of textbooks is generally used in the same region.
3. Different A versions of editing module traditionally use axiomatic theorem as auxiliary line and other geometric methods to solve solid geometry problems. Version B is a new content, that is, following the knowledge of the plane vector part of Volume One, using the method and concept of space vector to solve solid geometry problems, and using algebraic calculation to solve geometry problems.
4. Different emphasis: Version B pays more attention to revealing the essence of concepts and improving mathematics literacy than Version A, so it is suitable for students who are interested in mathematics, while Version A is suitable for self-learners or students who don't have so high requirements for high school mathematics. For example, it is also solid geometry, version A focuses on the examination of spatial imagination thinking, and version B focuses on the extension of concepts.
