The office door was closed, so Su Ya knocked on it.

Soon we could hear sounds coming from inside.

"Please come in."

Su Ya pushed open the door and went in, and saw Yan Su sitting in that chair with a smile on her face.

"Su Ya, is something the matter?"

"Teacher Yan, I don't agree with this score. I think you made a mistake."

"Where is Su Ya from?"

"I lost three points on the last question."

"Oh, this? I asked the examiner, and they said your answer is the same as the standard answer, but the steps are different, so they deducted three points."

"Just because the steps were different, they deducted three points from my score." Su Ya found this reason somewhat amusing, and even began to wonder whether she should continue studying here.

That's right.

"Then please take a look at the test paper from last time, Teacher Yan."

Su Ya placed the other test paper on the table. Yan Su picked it up and looked at it from beginning to end. The beginning was exactly the same, even the handwriting was identical. If she didn't know it was handwritten, she would have thought it was a photocopy. However, at the last question, although the answers on both papers were exactly the same, one paper had 10 points and the other only 9 points.

"Teacher Yan, I need a reasonable explanation."

"Su, I'll go talk to the principal about this and let you know as soon as it's resolved."

"good."

After saying that, Su Ya turned and left.

For some reason, Yan Su felt that this student was quite extraordinary just by looking at her from behind. There was a subtle but unyielding pride about her.

Yan Su quickly took the exam paper to the principal's office and explained the situation.

"Principal, look."

Principal Wang made a phone call and spoke to the person inside.

"Assistant Lin, go and fetch the examiner."

Soon, the teachers who were grading the papers arrived.

"Principal Wang, what can I do for you?"

"Well, let Teacher Yan explain this matter."

So Yan Su then discussed the grading of the last major question on both exam papers.

No sooner had I finished speaking than I heard a teacher say something.

"Teacher Yan, I think we should grade the papers based on the standard answers. Otherwise, how can we grade these papers?"

Upon hearing this, Yan Su retorted without hesitation: "If the standard answer is wrong, should we still follow it?"

"What a joke, Teacher Yan, how could the standard answer be wrong?"

"What if?"

"I guarantee that the standard answer is correct."

"What if we're wrong this time?"

"It can't be wrong."

Ring ring, a cell phone rang urgently.

"Wait a moment, I need to take this call."

"Please go ahead,"

Yan Su walked outside the office and had just answered the phone when she heard Lao Chi breathing heavily inside, as if he had done something strenuous.

"Old Yan, where are you? I just got off at school."

"Principal's Office."

"Where are you and what are you doing? Has Su Ya's matter been resolved?"

"Not yet. Why don't you come over?"

"Okay, I'll be right there."

After finishing her sentence, Yan Su hung up the phone and returned to her office.

He then continued, "Principal Wang, Teacher Chi was in charge of grading the papers last time, and he has something to say."

"Old Master Chi is back?"

"They just called me; I just entered the school gate."

"Everything over there is done. Shouldn't we let him rest for one night and come back tomorrow?"

"Something must have happened at home."

In fact, Yan Su knew that the reason Chi Mu came back so quickly was because he was afraid that the promising students he had his eye on would be kicked out of the school.

Soon, Mr. Chi arrived at the principal's office.

"Principal Wang."

"Elder Chi, please have a seat. How come you're back so soon? Have you finished taking care of things over there?"

“It’s all taken care of. I’m afraid if I don’t come back soon, the promising math students I’ve been eyeing will be driven away by you.”

The fact that Mr. Chi wanted to take Su Ya to participate in the International Mathematical Olympiad had spread throughout the school, and almost everyone knew about it. Many people advised him to give up, but he refused.

He had a premonition that Su Ya would be a key figure in next year's International Mathematical Olympiad.

"Mr. Chi, please take a look at these two papers."

Yan Su handed Su Yakao's two exam papers to Teacher Chi.

"Wait a minute, Principal Wang, before you look at the papers, could you please ask all the homeroom teachers of the second-year classes to come over?"

Principal Wang called Assistant Lin without asking why. Soon, the homeroom teachers from each class arrived.

Mr. Chi picked up the two papers and saw that one of them only scored 97 points. This shouldn't be the case. After quickly browsing through the papers, he discovered that the last question was only worth 9 points.

Then, Ikegi's expression immediately turned ugly.

Who graded this exam paper?

The teacher who was grading the papers stepped forward.

"Professor Chi, I graded this paper."

Chi Mu glanced at him. He wasn't familiar with him. The teacher opposite him was about twenty-seven or twenty-eight years old. He should have graduated a year or two ago and was probably a new teacher who hadn't been here long.

It's really no wonder that Mr. Chi remembers them. Those who have been with the school for seven or eight years are the ones he remembers, such as Principal Wang and Yan Su.

"You only gave 9 points for this last question?"

"Yes, Elder Chi."

Tell me your reasons.

Old Chi had an imposing aura that commanded respect without anger, so the teacher grading the papers had no choice but to bite the bullet and speak.

"This score is based on the standard answer. This student's answer to this question is correct, but the steps are different from the standard answer. There are two steps missing from the standard answer."

"So you thought it was wrong and only gave it 9 points."

Which university did you graduate from?

The examiner didn't know why Mr. Chi would ask him which school he graduated from, so he felt a little uneasy, but he still didn't dare not answer.

Ocean University.

"Which teacher did you study under?"

"Teacher Jiang."

"Jiang Yan?"

"right?"

Then I saw Old Chi take out his phone and start looking through it.

The teachers grading the papers became even more nervous. All the teachers who could come to work at Kyoto No. 1 High School were graduates of the four top universities in China. Kyoto No. 1 High School would not even consider teachers who graduated from other universities.

"Mr. Chi, what are you trying to do?"

"I want to ask Jiang Yan, how exactly did he mislead students? When did mathematics, a subject that requires broad thinking, become a subject with only one answer?"

These words startled the teacher grading the papers, causing beads of cold sweat to appear on her forehead even in the heated room.

He then recalled his teacher, Professor Jiang from Ocean University, who had repeatedly said that learning has no end, and mathematics is a kind of expansive thinking. There is never just one correct answer. Don't always limit yourself to standard answers; this will restrict your thinking abilities. Don't assume that finding a certain answer means it must be correct. Don't give up exploring and developing new mathematical thinking. This applies not only to mathematics but to everything; there is more than one correct answer. Don't assume someone else's answer is wrong just because you are unfamiliar with it, don't know it, or don't understand it, without critical analysis.

"Elder Chi, I was wrong."

"Then where you went wrong."

"We should not judge right or wrong based on our own subjective opinions."

"There's still hope."

"Do you know why I gave this question 12 points?"
