I really just want to be a scholar

Chapter 15 The Provocation of Mathematical Representatives
In Yingyuan Private High School where there are many beauties, Ning Qingjun is the most conspicuous and the most beautiful one. Although she only wears school uniform all day long, it is still difficult to hide her beauty and temperament. I don’t know how many boys will secretly look at her, passing by the class window every day There are also many boys in other classes and even senior boys.

It's just that everyone knows Ning Qingyun's character, and no boy dares to talk to her easily.

Qin Ke is the one with the thickest skin, anyway, he is Ning Qingyun's deskmate, and he has no idea about Ning Qingyun, so he sat down carelessly and said, "Thank you, school committee, thanks to you, today's Chinese I did very well in the exam."

"This is the result of your own hard work." Ning Qingjun replied calmly, her expression didn't seem very happy.

"Hey, who made our school committee unhappy? For the sake of borrowing my notebook, I'll teach him a lesson for you!" Qin Ke rolled up his sleeves on purpose.

"Boring. You might as well study more when you have time for this nonsense. You'll be smiling all day long and you won't let the teachers worry about you."

Ning Qingyun rolled his eyes at him, as if he wanted to ask something, but he glanced around at him, then lowered his head to do the exercises, and ignored Qin Ke.

Qin Ke glanced and saw that Ning Qingyun was doing the last big problem and three additional problems in mathematics in the afternoon.Ning Qingyun's memory is so good that she actually wrote down the four questions silently.

"Student committee, the exam is over, why are you still doing this question?" Qin Ke saw that there was a step specially circled in the comprehensive question, and after a little thought, he understood: "School committee, what are you doing? Did you answer the big question wrong?"

"Yeah." Ning Qingyun bit her red lips unwillingly and nodded, and couldn't help but add another sentence:

"In order to do the additional questions later, I did this comprehensive big question in a hurry. I made a mistake here, and I made a wrong step. I only realized it after handing in the paper. I guess 20 points for the big question will be deducted. 13 points. I did the first and second additional questions later, but I’m not sure if I made any mistakes. Difficulty."

"Let me help you take a look." Qin Ke has been a fine person since he was a child, and he has already seen what the school committee is implying. It's just that the girl is tender-skinned and a little arrogant and reserved. Impossible, he simply and proactively reached out to take the notebook on her desk.

"Hey, you..." Ning Qingyun wanted to hold it down, but Qin Ke moved quickly and took the book away.

Seeing that Qin Ke had already watched the process of the answer he wrote, Ning Qingyun hesitated for a moment, his face blushed slightly, and asked in a low voice that only the two of them could hear: "Yes... Did you do anything wrong?"

"The first additional question is correct, and the second additional question is also correct, that is, you chose the most troublesome conventional way to solve the problem, which wasted a lot of time in answering the question. In fact, the principle of tolerance and exclusion is the fastest, you see... ..."

Qin Ke took the pen in Ning Qingyun's hand and began to write in her notebook.

"At this point, you can directly use the principle of inclusion and exclusion to get the final result. It can be seen that there are 59 permutations that satisfy the meaning of the question."

Ning Qingyun listened carefully while looking at his correct handwriting, a faint admiration could not help showing in the beautiful Danfeng's eyes.

This guy's math level is really higher than his own!Why didn't I think that I could use the principle of tolerance and exclusion?
"The third question is actually not difficult. You see, there are two ways to prove it, one is the method of mathematical induction, and the other is the method of introducing complex numbers..." Qin Ke wrote while speaking.

"Wait, you've written this far, I don't understand. Is there such an assumption in the first and second mathematical induction?" step asked.

"Oh, I used the two-parameter induction method in the last step. This is relatively rare, and you may not have seen it. In simple terms, it is proving the proposition p(n, m )Time……"

Ning Qingyun nodded again and again, and glanced away, noticing that Qin Ke's originally lazy and ruffian face had become focused and serious, and his eyes were clear with the light of wisdom, he couldn't help but think to himself, this guy It's not so annoying when you study hard...

This scene is completely different in the eyes of others.

Originally, Ning Qingyun was the object of attention. At this time, she and Qin Ke were a little closer, and her gaze was still on Qin Ke's face. There seemed to be a soft light, and her pink lips were still slightly raised. , revealing a beautiful and shy smile that is rarely seen at ordinary times.

For a while, I don't know how many boys I stared at, and I don't know how many jealous jars I overturned.

The boys all knew that Ning Qingyun was an unattainable and unattainable flower, and they didn't expect to have anything to do with her. After the lessons learned from those few who confessed bravely but were punished, they didn't even have the courage to confess. But it doesn't prevent the boys from secretly liking this smart, beautiful, cool and gentle school committee member at the age of first love.

Seeing this scene at this moment, how can I not feel uncomfortable?
Even Qin Ke's roommates couldn't help but want to pinch Qin Ke a few times, let alone others.

Wu Shaocai, the representative of the mathematics department, is one of the crushes. His mathematics score is second only to Ning Qingyun in the class, and his seat is only a few rows away from Ning Qingyun. Zhu stepped forward and interrupted: "What are you discussing?"

It was only after Wu Shaocai's interruption that Ning Qingyun came back from solving the problem, and found that he was only a fist away from Qin Ke. He blushed and retreated to his seat.

As for Wu Shaocai, Ning Qingjun dealt with them quite often, after all, the academic committee directly communicated with the representatives of each department.

However, the original explanation process was interrupted, and Ning Qingyun couldn't help but frowned, and her voice was a little colder than usual: "We are just discussing the test questions for the math test in the afternoon, Wu Shaocai, please come up with the additional questions later. gone?"

Wu Shaocai took a peek at the notebook in front of Qin Ke. It was indeed a mathematical problem-solving method. He thought it was written by Ning Qingyun, so he said with a dry smile: "No, this time the topic is more difficult. I barely finished the last synthesis. It's time to hand in the big questions, and I haven't had time to read the additional questions. How about you, the school committee?"

"I made a mistake in the comprehensive question, and I couldn't solve the last additional question."

Seeing that Ning Qingyun was not in high spirits, Wu Shaocai didn't dare to ask her any more to make her unhappy, so he turned his head and fired at Qin Ke.

He asked strangely: "Qin Ke, how did you do in the math test? The teacher praised you in the last math class. This math test shouldn't be difficult for you, right?"
