1, consolidate the foundation

Including concepts, formulas and theorems. If you can use yourself, find someone to talk to him once, and he will understand, and so will you. This is the same as the topic. I will, but if I tell others, I may not be able to make them understand.

2. Use what you have learned as a tool to solve problems.

There are very few knowledge points that I started to learn in primary school, so everything should be gradual. Take the calculation before the second grade, which basically belongs to this, and the calculation at the same level goes from left to right.

Therefore, we need to use what we have learned as a tool for examining questions, rather than just saying what we have learned. Just as we have learned to add several identical numbers, we will use multiplication to calculate them quickly and accurately. After the fifth grade, we learned to raise the common factor and learn to construct the same number flexibly. These are the tools that we learn and use flexibly.

3. Summary

This is what many students lack. A problem can be done, in other words, it may not be done. In fact, this situation belongs to, do not summarize, do not know how to be flexible. You can't infer from one topic to another. In fact, there are many similar problems, and we can relate them, so that the learning efficiency will naturally improve.
