If you really can't, go to class with questions or ask the teacher. In this way, we can really figure out which knowledge point this question examines and how to solve it smoothly. Think about the difference between your own thinking and the teacher's thinking. Why do teachers use this kind of thinking?
Do a comprehensive study, draw inferences from one another, and you will be able to solve the same problem in the future, and also increase your own problem-solving ideas.
It is impossible to answer all the questions at first sight in learning. When encountering difficulties, it is the correct learning attitude to think independently first. Although you can't get the correct answer through your own analysis and calculation, you can always solve a direction.
