When I said the three kinds of words, the students in the class suddenly started to talk about it.

Three? No way.

"There are so many solutions to this problem? I don't know any of them. A girl said with a sad face.

"Me too." The other girl nodded in agreement, "I don't know one solution, let alone three." ”

Some girls said sourly, "There are three kinds of thoughts?" It's funny, it must be bragging, bragging doesn't make a good draft, don't you see the face of the math teacher? The teacher doesn't know the three solutions, so I don't believe in Yoyokai. ”

"I agree, didn't you hear what you just said? What law does she have for multiple-choice questions, and there are three solutions to this selection? ”

The argument grew louder and louder, and the old math man organized the discipline, "Quiet. ”

The class was silent.

"You say, I'll write on the blackboard." The old math man picked up a piece of chalk from the lectern and prepared it on the blackboard.

After a long sigh, he said, "The first method of this problem is to set X first, and then use the trigonometric function ......."

Very well, wrote a blackboard.

The math old man's hands were sore at the end of his writing.

Looking back, he looked at the steps given by the question.

The steps are okay, but not for first-year high school students.

It's too hard for them.

"Do you understand?" The old math man asked the students around him, all with confused expressions.

They don't understand.

"Teacher, I have a second way." Nian Youyou raised his head proudly, "The second way ......"

For another ten minutes, there was no place on the blackboard to write.

Old Math Man: ...... This is what God operates.

What kind of abuse did he make?

"Do you understand this?" The old math man shook his head, "This method is not the content of high mathematics, if you go to college and specialize in mathematics, you will." ”

"Teacher, I have a third one." Nian Youyou raised his hand and replied, "Teacher, I think the third method is simpler than the first two. ”

"Tell me about it." The old math man wiped his chalk-covered hands and said to the class, "Listen, I'm not going to write." ”

He couldn't even write.

"Third Method ......"

After five minutes, the chanting stopped.

Many people still have confused expressions.

said that the girl who was bragging about Yoyo had a very red face.

It's too a slap in the face.

"Forget it." The old man in mathematics waved his hand to Nian Youyou and motioned for her to sit down, "Nian Youyou's all talking about college algorithms, who can do it in high school?" ”

"Teacher, I will do it in high school." Nian Youyou didn't wait for the math old man to agree and stood up, "I'll also learn algorithms in high school." ”

"Then why didn't you just say it?" The old man in math has a black line.

"I just wanted to pretend to be a force." Nian Youyou replied naturally.

All:...... You're the devil, or Xiu'er.

It's too showy.

"I don't need you to say it." The math teacher was worried that there would not be enough time to finish the lecture, so he said to Nian Youyou.

"Oh, good." Nian Youyou sat down, and after sitting down, he whispered to Mu Xichen, "Lao Tie, do you understand the steps I just took to solve the problem?" If you don't, I can teach you. ”

"Thanks, but I understand." Mu Xichen lowered his head, didn't listen to the old man in mathematics, and did it himself.

Old Iron ...... What happened?

Such a difficult solution will be too powerful.

She also thought about using the topic to chat with Lao Tie a few more words to cultivate her feelings.

It's in the soup......

"Lao Tie, why don't you listen to the lecture? If you don't listen, you're not a good boy. Nian Youyou said critically.
