The real logic of solving mathematical problems, Woods' original "Five Steps of Thinking of Solving Mathematical Problems", took about 14 days to develop. (1) Determine chapter knowledge points, core knowledge points (required test) and common test knowledge points. In fact, I just thought about what knowledge points are often tested in this kind of topic. This step is to better construct the knowledge system and cultivate the questioner's consciousness. (2) take the topic apart and divide it into sub-topics. (That is, unload the topic, break it into eight pieces, and decompose it) ③ Translation and transformation, corresponding the stem of the topic to specific knowledge points, and determining the application of knowledge points (knowledge points are packaged into the stem of the topic, and all we have to do is to take off the stem of the topic and turn it into knowledge points) ④ Push forward from the stem of the topic and push back from the question. (Forward push is relatively simple, everyone is using backward push and problem-oriented thinking, because we need to know how the topic is made) ⑤ Carefully calculate to ensure that the inspection ideas can be traced back and sorted out.
