At the beginning of the story, I saw Da Zhuang angrily walk into the classroom and take out his own exam papers, and the teacher took the papers and said, It seems that you have not studied mathematics well, but don't be sad, the teacher will teach you well. But Da Zhuang said, play, what did I do wrong? The teacher pointed to the paper and said, two plus two equals four, you write 22. Da Zhuang said, why not 22? The teacher took out a colored pen and said, I have two pens in my hand, and then I take out two, how many are there when I put them together? Da Zhuang said: 22, and then angrily left the classroom. The next day, a temperamental couple came to the school, it was the strong parents, the two were smiling and polite to the teacher. Mom asked the teacher, what did Da Zhuang do wrong? The teacher replied, your children are five years old, actually wrote a two plus two equals twenty-two, two people are blindfolded, right? Surely not, do you mean my son is stupid? Why do you think you're right and my son is wrong? The teacher was momentarily confused, you two will not even two plus two equals a few, you don't know it, followed by a man's ridicule, the teacher is thinking that you are going to fight if you continue to talk, hurriedly began to escape, the result is that the woman behind you said, I am going to go to the principal to sue you, waiting to lose your job.
