1. Write down what you learned today.

2. Write down what you didn't master today.

3. Establish your own plan to conquer knowledge in the future.

4. Make a long-term plan for your future math study.

First of all, write down what happened today, make up something related to mathematics casually, then say that you think about it (nonsense-it took a lot of effort), then say that you still don't understand, and you are reminded by a casual sentence from others, and finally think of it. Finally, it turns out that mathematics is so useful that it is all around us. end
