Because the situation in our class was like this at that time. When you come back from the holiday, the teacher gives the formula paper, which is the name of the formula, and then you recite the formula. Later, there were 54 people in the class, and all four of them were right. . . .
The others are either missing or out of order, or out of order anyway.
In fact, you don't have to worry too much about this problem, and you don't have to remember the formula. What you need to do now is to calm down, then read math books, and then do examples. Do other examples if you have time, so that your memory will be hooked up, and the memory of the brain is like this. Because your formula is added in a short time and useless for a long time, your memory will gradually decrease, you think. . . .
So don't worry too much. When school starts, follow the teacher's footsteps slowly, and you will find that these things will appear slowly.
