The principal glanced at Zhao Beichen suspiciously and thought that this man looked gentle and easy to talk to.

Look at the male teacher who stood up. He has a frown on his face and the corners of his mouth are turned down. He doesn't look very pleasing to the eye.

It must be jealousy, the principal thought.

He waved his hand and said, "Oh, don't worry about that. Ever since Teacher Zhao took over that class, the grades of the students in that class have improved a lot. You all just need to learn Teacher Zhao's management system well."

The meeting place fell into silence for a long time, and finally it was Teacher Liu, who worked in the same office as Zhao Beichen, who took over the conversation.

"The principal is right. Although you can't learn anything else, you can still learn the management system."

"As for whether it's not useful in other classes, I'm not sure, but it's better to give it a try."

With Teacher Liu's words, the principal nodded with satisfaction.

"It's the last stage of senior year. All teachers, please work harder. We will definitely give you some time off to rest after we send off this year's students."

After the meeting, Zhao Beichen returned to the classroom and checked on the class for the teacher of the next class.

As soon as I walked to the classroom door, I heard the noisy sound in the classroom.

"This question is wrong! You shouldn't do this!"

"How is it wrong? Many good students wrote it this way, why are you different?"

"But there are many people who write the same thing as me. Yan Ruyu also writes the same thing as me. She is also a good student."

"...Being good is one thing, and doing it right is another. I can't be sure that Yan Ruyu is right."

"you......"

"Hey, you can argue all you want, but why bother with whether what I did is right or not?" Yan Ruyu supported her head and looked at the people on the stage speechlessly.

Yan Ruyu was also speechless. These people were arguing about right and wrong, and the argument was so intense.

But I have never participated in it and have always been solving problems seriously.

I didn't expect that just for such a question, you had to bring up whether you answered it right or wrong. The important thing is, it doesn't have much to do with whether you are doing well in your studies.

Yan Ruyu took a look at the question and thought, if she hadn't done it before at home and been corrected by Professor Zhao, she might have actually gotten it wrong.

Yan Ruyu originally wanted to go up and help them tell the correct answer, but when she saw them arguing endlessly, she lost interest.

You might as well sit down there and wait for the people upstairs to stop arguing. It won’t be too late to go up later.

Now this is not going as I wish, I have to go up and teach it myself now...

The man looked at the person who was lazily leaning his head and felt a little uncomfortable, but he didn't know what to say.

All I can do is say stubbornly, "Student Yan Ruyu, whether you are right or not is not something we can control, but this person insists that what you wrote is exactly the same."

"It's not that I did it on purpose, but for this question, the good students in the class all wrote it this way, so what she wrote is wrong. Similarly, yours is also wrong. However, we didn't drag you in on purpose."

Yan Ruyu raised her eyebrows and glanced at the girl.

After pondering for a moment, I remembered that I had come to myself after finishing the questions just now and wanted to check the answers with myself.

Yan Ruyu knew that what she wrote was right, so that girl was also right.

However, she also knew that she couldn't just casually say that what she wrote was correct. It would be hard for people to believe it, so it was better to explain it to them clearly.

"You are already a senior in high school, and you are still arguing about the right and wrong of a math problem. If you think you are right, why not explain it to your classmates?"

"Now that I'm mentioned, let me talk about it first and see who is right between what I did and what those people did."

As she spoke, Yan Ruyu put down her hands that were supporting her head, slowly stood up and walked towards the podium.

Seeing her sister was about to go up, Yan Fangxiu grabbed her hand.

He whispered, "Ruyu, don't be so stubborn. Are you sure you are doing the right thing? Don't let anything go wrong."

[I haven't shown it to my sister yet, I haven't told her about it yet, and even before I've gone up to explain it clearly, my sister already thinks that something will go wrong with me? Could it be that my sister doesn't believe in her own abilities? ]

When Yan Fangxiu heard her sister's thoughts, she panicked on the spot.

Because that wasn't what she meant at all. She was just afraid that Ruyu would be taken advantage of by that girl.

Yan Ruyu pulled her hand back and said calmly, "Sister, I'm just going to go up and talk about my ideas, it's nothing."

He walked up to the podium, picked up a piece of chalk, and walked in front of the girl.

With a slight smile, he said, "Please move aside. I want to stand here and give a lecture."

The girl clenched the chalk in her hand and stepped back reluctantly.

Yan Ruyu could see that it was not that she disliked herself, but she was just a little embarrassed and afraid of being laughed at by others.

Yan Ruyu raised the chalk in her hand and began to write down her solution process on the blackboard.

She explained the reasoning and calculations for each step in detail, using simple and clear language to explain to the whole class.

Her voice was gentle and confident, attracting everyone's attention, including the people eavesdropping outside the door.

After her explanation, the students gradually understood the key to the problem and nodded in understanding.

Some students began to calculate by themselves to verify whether Yan Ruyu's answer was correct.

As their calculation results gradually emerged, most of the students discovered that Yan Ruyu's answer and algorithm process were correct.

Yan Ruyu did not get carried away by her correctness. She continued to explain the questions occasionally raised by her classmates and patiently answered every question.

She uses simple methods and vivid examples to help everyone understand more deeply.

The whole explanation process lasted nearly half an hour. Finally, Yan Ruyu summarized the solution to this problem and some precautions.

The whole class praised Yan Ruyu's explanation and said they benefited a lot from it.

"I never expected that the topic we sat together to discuss would be wrong."

"Fortunately, Yan Ruyu explained it to us clearly. Otherwise, if this kind of thing happened during the exam, we would be completely wiped out."

"Yes, thanks to classmate Yan Ruyu."

"Student Yan Ruyu's current study is really different from before. She can even avoid questions with traps like this. She's amazing."

The girl no longer insisted on speaking. She listened to Yan Ruyu's explanation silently with an expression of understanding on her face.

Yan Ruyu had always been paying attention to her, fearing that she would feel resentful towards her because she had written it correctly.
