Taking a deep breath, ignoring the complicated eyes of his classmates, Chu Nan walked to the podium with a calm demeanor.

Take out a piece of chalk and prepare to solve the problem.

This is a conic curve problem, which mainly examines the understanding of the nature of curves and equations, and the difficulty can only be regarded as difficult.

This question can stump the vast majority of students mainly because it is very biased in the test, and it is necessary to put aside fixed thinking and think about the problem flexibly.

In the past, conic curve problems, whether simple or complex, finally had a general core solution idea, first set but not solved, and finally through the known relationship of the problem, eliminate the complex algebraic relationship, and then obtain the requirements of the problem.

The math teacher talked about this problem on the blackboard, very biased, and there are a few hidden pitfalls, if you blindly use the idea of design and unsolved to solve the problem, it will only become more and more confusing, and you can list dozens of formulas, and finally you can't eliminate it.

The math teacher stood aside when Chu Nan took the chalk.

He felt the breath of a scholar rushing to his face.

Where do you seem to have heard the name Chu Nan?

The math teacher couldn't remember a bit, as if he had heard someone talk about it a few days ago.

......

Just then, the bell rang for the end of class.

Wang Lele breathed a sigh of relief, and it was good to get out of class.

As soon as Chu Nan wrote out the word "solution", he heard the math teacher say, "Rest for a while, and continue in the next class." ”

"Teacher, the next class is PE. ”

"By the way, your PE teacher asked me to tell you that the final exam is coming soon, and he wants you to get a good score, so in this PE class, let me give you a good review of mathematics. ”

The math teacher seemed to have expected this trick, and after finishing speaking, he walked out of the classroom with a thermos cup, and did not even take the math book that was resting on the podium.

There was a wail from the audience.

Chu Nan had no choice but to take the opportunity to return to his seat.

"Brother Nan, if only you were half smart? You're too witty, aren't you!"

"What's wrong?" Monk Chu Nanzhang was confused, what's wrong?

"You said you, you said you" Yang Wei showed envious eyes, "You saw that class was about to end, so you deliberately relieved Wang Lele!"

"In this way, you don't have to do this question, and you can still get the favor of the goddess Wang Lele, it's really killing two birds with one stone, you are too treacherous!"

"I'm Cao, this kind of good thing, why didn't I think of it!" Yang Wei regretted.

Chu Nan thought about it, Yang Wei thought like this, it seems to make sense!

Chu Nan almost believed this statement.

But, I'm really just trying to pretend to be a force!

God is pitiful, I was really just pretending to be a force at the time, and I didn't have any extra thoughts at all.

It was not because of the lust that Wang Lele relieved the siege and captured her heart!

Chu Nan smiled bitterly, and explained to Yang Wei again and again, but Yang Wei didn't believe anything.

Chu Nan thought about it again, Wang Lele is childish and juru, the fat place is plump, and the thin place is skinny, even if he misunderstands, he is not a loss!

On the contrary, it seems to make a lot of money!

If Wang Lele can be his girlfriend, he should have more face.

Well, it's so fragrant!

Wang Lele's side, as soon as the bell rang for the end of class, she lay on the table and had no face to see.

She was red-faced, and rumors were rife in the class, all about her and Chu Nan.

A few female classmates who had a slightly better relationship with her saw the teacher leave, and immediately surrounded her like paparazzi.

"Okay! Without making a sound, I hooked up the new class grass. ”

"Lele, I can't see it, you're too good. ”

"Underground romance, tell me honestly, how long have you been with Chu Nan?"

"Don't say it, Chu Nan was quite handsome when he just relieved Lele!"

"Tsk, we're going to have one more couple in our class. ”

No matter how Wang Lele explained to them, no one believed that they were innocent, but the more they talked, the more mysterious they became.

Wang Lele is about to cry, you have to believe me!

Murong Xue has an extremely cold temperament and doesn't like to be watched, so she pulled Wang Lele at the same table and used the excuse of going to the toilet, and finally got rid of the female classmate who was burning with the fire of gossip.

Walking outside the classroom, lying on the railing, taking a few breaths of fresh air, without the ambiguous eyes of his classmates, Wang Lele calmed down, and the blush gradually faded from his face.

"Classmate Wang Lele, tell me honestly, where have you and Chu Nan developed?"

Just rested for a while, and before he could calm down, Wang Lele almost vomited blood when he heard the words of his best friend.

"Why don't you even believe me? I'm innocent, they all misunderstood me. ”

Murong Xue nodded, "I know they misunderstood you!"

"Then you're still kidding me!" Wang Lele said angrily.

Murong Xue showed an ambiguous look and quipped: "I remember someone, one morning, somewhere, but he said something to me." ”

"Sister Xiaoxue, look at the handsome guy, it's still a handsome guy!" Murong Xue exaggeratedly imitated Wang Lele's tone when he spoke, with a spring face.

Wang Lele's face was so red that she could already drip blood, she said it herself, yes, and the place where she spoke was the railing where she was lying on her stomach now, and her position had not even changed.

"Murong Xue, you ......" Wang Lele stomped his feet and said angrily, "If you do this again, I'm going to be angry." ”

"Alright, alright, no kidding,......"

......

Even good girlfriends misunderstood Chu Nan and Wang Lele, and it is conceivable how many people will have the same idea.

"Lying grass, Chu Nan's goods, it's too cloudy!"

"Made, why didn't I think of it, Wozhi, I regret it so much. ”

"Lao Yinbi! ”

......

Chu Nan sat in the last row, leaning against the back door.

There are many students who come in and out of the back door after class, and when they see him, most of them show ambiguous expressions, some male classmates have bad eyes, some are purely eager to replace him, and some are the eyes of rivals.

But they all have one thing in common, and that is envy.

Wang Lele looks cute, and he is childish**, and his voice is also very soft, so he can almost be a cute and legal Loli.

Who wouldn't want to find a girlfriend of this type!

I can't be envious.

Even Fang Hao felt lost in his heart.

Even if he is not familiar with Wang Lele, even if he does not lack a beautiful female spare tire.

But who would refuse a cute and cute legal Lori!

This is probably a common problem of men.

"Hmph, it's a pity that Chu Nan never thought that the next class would be math, I'll see how he ends later. ”

Fang Hao couldn't help but look up at the blackboard, the difficulty of this question was beyond imagination.

"I don't believe that Chu Nan will do this problem, even if he is good at physics, he will only be able to hit the street when he encounters mathematics. ”

"When Wang Lele recognizes Nan's true face, I believe she will know who is suitable for her. ”

"It's best if Chu Nan makes a fool of himself in public in the next class, I don't believe it, his luck has always been so good. ”
