But this is not a mathematical problem.

In retrospect, when you were solving those problems, you should be in a hurry.

The brain is shorted, right?

This is because I don't have enough confidence in doing the problem, so I'm not sure when to finish it, so I'm anxious to write it down.

Causing extravagance and waste, 2+4=8.

Only by building up confidence and trying to figure out the teacher's intentions (if you do more questions, you will find that the questions are regular and there will be hidden information)

Having said so much. . Actually, I'm talking about my own experience and experience. . And I have been baptized by the college entrance examination ~ ~

I wish you can finally walk out of your misery with satisfaction!
