The homeroom teacher had a look of disdain on her face when Qin Shu came up with the question. Did they think her teaching certificate was fake?
When she looked at the question on the blackboard, she was stunned once more.
This question...
The students below looked at the question on the blackboard and were stunned for a moment because they seemed to have seen this question before but did not know how to solve it.
Jiang Yu stared at the question for a long time and couldn't figure out how to solve it. He turned around and asked Fu Tingyan, "Tingyan, do you know how to solve that question?"
Fu Tingyan had been watching as Qin Shu wrote down the question. He could say that he knew how to answer the question, but he could also say that he didn't know how to.
He knew how to because he knew the formulas used in the first half of the question like the back of his hand.
He also didn't know it because there was an unknown field added to the question.
If this question appeared in the college entrance examination, he wouldn't get any points even if he got half of it right.
His pitch-black eyes looked at Qin Shu, full of doubt and disbelief.
Qin Shu looked at the homeroom teacher's stunned gaze and raised her beautiful eyebrows. "Miss, how do you solve this question?"
The homeroom teacher was stunned and glanced at Qin Shu. Qin Shu looked as if she really wanted to know the answer and did not seem like she was deliberately embarrassing her.
"It's class time now. Wait for me to solve this question for you."
Seeing the homeroom teacher shirk, Qin Shu pretended to be distressed and said, "Didn't you say that we should not drag things on while studying? If we don't understand something, we should get it figured out straight away so that we don't forget it."
"Didn't I say that it's class time now? Don't tell me you want so many students to wait?" The homeroom teacher's expression was very ugly. Qin Shu was deliberately embarrassing her.
At this moment, Fu Tingyan suddenly said, "Miss, I don't know how to answer this question either. I hope you can explain it to me."
Jiang Yu, who was always by his side, naturally also shouted, "Miss, just take some time to explain the question."
Qin Shu turned around and glanced at Fu Tingyan. He, who always slept in class, actually didn't sleep today and even spoke up?
The homeroom teacher's face alternated between purple and white. Fu Tingyan and Jiang Yu had both spoken and she didn't even have a reason to decline.
She took the chalk and walked to the blackboard. She stared at the question on the blackboard. Sweat on her forehead dripped down unconsciously.
Qin Shu glanced at the homeroom teacher. The sweat on her forehead was like beads with a broken string, dripping drop by drop. She was like a student who couldn't do a question.
The only difference was that a student who could not do the question would be scolded.
Teachers who could not do the questions would lose face.
In fact, there was a mistake in this question. It was easy to overlook. As long as one understood it, it would be easy to solve.
She walked down the steps and returned to her seat.
When she took out her computer, she found it was already time for class. This also meant that she had missed another part of the lesson content.
Although it was a waste of time, it was worth it to embarrass the form teacher.
Time passed by minute by minute, and only half of the question on the blackboard was solved.
The homeroom teacher's expression was very ugly at this moment. She bit her lips and wanted to throw away the chalk and leave.
However, as a teacher, doing this would only make her students laugh at her.
Fu Tingyan saw that the teacher still had not been able to solve the question, so he couldn't be bothered to look at it. He turned his head and glanced at Qin Shu. He could roughly guess that she was giving the teacher a taste of her own medicine.
How ruthless!
Fifteen minutes had already passed, causing the homeroom teacher to completely embarrass herself.
In the end, the homeroom teacher had no choice but to find an excuse. "My stomach suddenly hurts. Study by yourself for the rest of this class."
After saying this, she hurriedly left.
As soon as the teacher left, someone shouted.
"The teacher ran away. "
The classroom immediately exploded with all kinds of comments.
