"Shu Lin, please get up and say what is wrong with this formula."

"Shulin, you go to the blackboard and explain why we use this formula."

"Shulin, tell me what affinity number is."

"Comfort, Comfort, Comfort!!"

Shulin:

"Sorry, I don't know which formula it is."

"I'm sorry, I really don't know."

"Didn't you bring your brains to class? You don't even know such a simple question? Don't you know the formula and don't know the class? Shu Lin has been up and down several times, and every time she has been baptized and crushed by his extremely vicious words, and the rare arrogance and domineering on weekdays have been trampled to the ground again and again.

"What is an affinity number."

Shu Lin, who was named again, was troubled for a while, just now she said that she wouldn't be able to, why did she still ask her this kind of question, deliberately.

Helplessly, Shu Lin could only get up slowly and droop his head. She was the only one in the whole classroom who felt sad, and everyone else seemed to have a bit of envy in their eyes.

"Do you have a brain? Don't think with your toes without a brain? Shu Lin knew that he would deliberately make things difficult for her in this class, but he didn't expect that it was already to the point of being attacked in life. If you can't think of something in your head, and if you think of your toes, it's really genius.

Affinity number, what the hell is that, how would she know, God, who will save her. What about her alumnus, why didn't she show up today, her legs began to weaken.

No matter, just guess one, "Uh, it's probably two numbers that love each other, right?" Shu Lin said lifelessly, he would definitely be laughed to death, where will there be people's feelings, and they still love each other.

As a result, she waited for a long time without a single movement, and everyone looked at her with very surprised eyes. It doesn't seem to be the kind of ridicule that seems to be imagining.

Shu Lin immediately raised his head and looked at Cheng Hecheng on the podium.

"The meaning is almost the same, we have friendship between people, and there is also a special relationship between our two numbers and numbers. If we say that the sum of all the factors of a and b is equal to b, and the sum of all the factors of b is equal to a, then we say that a, b is a pair of affinity numbers. ”

"Such a pair of numbers is very difficult to find, as difficult to find as a bosom friend, and it is called 'friend number'. The proposer was Pythagoras, who found that the affinities of the first pair were 220 and 284. He said that friends are these two numbers, one is you and the other is me, and friends are the shadow of your soul, and they should be as close as 220 and 284. ”

"Later, in the preaching of the Bishi school, it was summarized that friendship needs to be talked about between people, and numbers can also love each other, so the number of affinity is also called the number of blind dates."

For the first time, Shu Lin felt that the human brain could really say a lot of strange things, a simple ranking explanation, in front of a professional person, he could talk eloquently, tell its origin story, and tell its legend. It's like an old friend.

It was also the first time she listened to the lecture so seriously that she forgot that she could sit down, she used to think that mathematics was really difficult, so difficult that it was as difficult as no answer, no clue. But at that moment, she suddenly felt that the world of mathematics was enough to be so emotional, and the legends about it were so beautiful.

"Silly?" Until the end of class, Shu Lin hadn't eased up, she was in a trance, but she didn't know why.

"Math is amazing." She was stunned and spat out what she wanted to say.

"You just found out." It means that he has discovered it a long time ago, and he has invested his body and mind in researching it.

"That's right. You're amazing. Cheng Hecheng was frightened by her gentle speech, was she praising him? It's a rarity.

She seems to have forgotten that he deliberately targeted her in class, but fortunately, the students in the class felt that this was her uncle's full love for her niece.

"For the sake of me praising you so much, don't wake me up next time I go to class, my calves have hurt recently, and it's inconvenient to sit up and sit." Almost, really almost, he believed what she said, it turned out that what she said before had the meaning of scolding him, just to want to live a better life in the future.

"Although you are ugly, you think beautifully."

"Cheng Hecheng! It's too much! ”

"Shen Xihe, can you solve these questions, I can't understand any of them, you said it yourself last time, you wrote your homework." It's because she called his full name out of control, and she fell into the trouble of making up for after-school homework, and if she didn't hand it in, she wouldn't have the usual points

Shu Lin didn't want to be annoyed by his mouth

"I look at it, look at it, it seems to be, it's a little difficult." After all, the physical education department doesn't need to learn mathematics, after all, I haven't touched that thing for a long time, after all, this is a positive question given by a professor, well, she, a self-proclaimed scholar, is also limited to the physical education department.

"Don't recite the Three Character Sutra to me, okay, this is the top priority now." Shu Lin looked at her hopefully, she was fine, but it was a little difficult

"Eh, what are you afraid of, he didn't ask you to write to him in person, I won't write it when I get it back, but someone will always write it." Don t forget that she is a backstage person she can't write qin ming who is in graduate school should be okay if he doesn t Senior Brother Jiang always will. Take 10,000 steps back and say, what does it matter if Jiang Zi can't send it, the graduate student apartment is full of graduate students, and there will always be one who will.

So, if I can bring you the topic back and write it, it's not a thing.

In short, anything that can be solved with connections is not a matter in Shen Xihe's eyes.

"Hmmm, isn't it just two questions, simple, minute-by-minute thing." Soon, the answer came from Shen Xihe's hand, and it was very standard, even Shen Xihe himself didn't understand a big push of numbers.

If there is someone at the head, it is fast.

"Thank you Senior Brother Qin for me, and invite him to come to the house for dinner." Shu Lin took the answer with joy and began to hum and chirp.

"Who said I was asking Senior Brother Qin?" Shen Xi He's face was arrogant.

Shu Lin raised his head when he heard the voice, didn't you say it yourself.

"Just such a small thing is going to use him? Can I fix it myself? Shen Xi He had a sè on his face.

Shu shook his head, sure enough, the women in love are all mentally retarded.

But now she only cares about whether there is an answer to this question, and after copying it, she thought that she still had to ask who it was, after all, the trustee used brain cells, and it was good to say hello when she turned around.

"Ms. Shen, by the way, the last thing you asked was sacred."

"Oh, Professor Cheng I asked." Shen Xihe looked innocent.

"Shen Xi Ho!" Shu Lin's voice rose by dozens of decibels, and she asked her to solve the problem he gave. As a result, she ran to him and asked, isn't that looking for death?

"Okay, I'm joking, didn't I say that Xiaomei and her boyfriend last time, isn't it a top student in the College of Science, ask him, ask him."
