Thank you for your professionalism.

Personal opinion:

1. Find the hot spots first. What is a hot spot? This is an abstract mathematical concept that many students don't understand.

2. Break them one by one. Your question is simple to say, but it is actually very difficult. I have done a lot of training in the enterprise, and I have come to the same conclusion: it is not difficult to understand a principle and an abstract concept by myself, but it is difficult to explain it clearly to people who don't understand it in the most concise way, so that they can't forget it.

There is no other way, and the specific problems are treated specifically. It is best to find something familiar to students (recipients), close to them and similar in life to model. Otherwise, it is ridiculous to explain simple concepts with more difficult concepts.

For example: I am explaining to my 6-year-old daughter what decimal means. I told her: you have a big bag of sugar. Now, put it in the small box, and each small box is just filled with ten pieces. You put a lot of small boxes, and then put them into big boxes, and a big box is exactly 10, and then put them into big boxes. She understood how 10 became 1. Hmm. How interesting
