"I'll go, Qiao Yingzi, who is in the top five on the big list, is in love with Chen Fan?"

"I found out that there was something wrong with the two of them, but I didn't expect that they would not carry anyone now!"

"Hmph~ Does she have my size?"

"emmm, I'm not in good shape, I can be small!"

……

The girls looked dejected, and they looked at the boys around them!

It was Fang Yifan's turn to eat

He had an idea

I saw Fang Yifan smiling as soon as he came up

Said:

"Auntie, I'm Chen Fan's good buddy, give me more meat! I can help your daughter get his contact information! ”

The aunt who is cooking is a person who has come over, and she knows that the hoe is well swung, and there is no corner that cannot be prying!

Besides, what do high school students know now?

"Okay, eat more, it's so big!"

"Hey, hey..."

It was the first time for Fang Yifan to enjoy this kind of treatment

Encounter, a smirk.

Ji Yangyang, who was sitting in the seat not far away, saw this scene and his face was already darkened.....

Chunfeng Middle School is not as strictly managed as an elite middle school

Therefore, no one cares about eating at the same table in the cafeteria

Around Chen Fan and Qiao Yingzi was a blank space

Two of you, one bite of you, one bite of me feeding, tortured countless single dogs!

……

Lunch break is the fastest time for high school students

Fun time.

However, the happy time is always the shortest, and when the bell rings, the heavy schoolwork begins.

That's the third year of high school!

The first class in the afternoon was math class.

The teacher is their homeroom teacher, known as Lee

Li Meng with an iron rod!

Mathematics is the most headache for most senior high school students. Because this thing is very abstract, it can only be understood, and rote memorization is almost useless.

Li Meng was talking about permutations and combinations on the podium

Without Huigen's classmates, I want to sleep, but I have to force myself to hold on.

Some students were groggy to listen, but because of the class teacher's class, they had to work hard and work hard.

"Looking at the appearance of the students, it seems that they can't accept it for a while, so let's start with a small topic to guide and guide."

Li Meng couldn't help but say, and wrote a math problem directly on the blackboard:

In an experiment, if 6 procedures are to be implemented sequentially, in which program A can only appear in the first or last step, and procedures B and C must be adjacent to each other when they are implemented, how many methods are there to arrange the order of experiments?

…

There were complaints from the podium.

"It's so hard!"

"Believe it or not, I didn't even understand the title, don't ......"

"Believe it, because I didn't read it either~~"

“...”

Li Tieba's title is not for nothing, as soon as he came up, he sorted out a difficult topic in last year's college entrance examination.

To be precise, it is the fifth question of the fill-in-the-blank question in last year's college entrance examination····· That is to say······ Hard!

In an instant, the students couldn't help but wail all over the field.

However, there are some individual reactions that are more special.

Several classmates with good academic performance, including Qiao Yingzi, all came to the spirit, all of them were like being beaten with chicken blood, and they were full of energy, and they were counted as soon as they took the pen and paper.

Hm

That's the difference between a student and a student

……

Fang Yifan looked at the topic with a confused expression, he belonged to the kind of topic that he couldn't understand. He turned his head and wanted to ask Chen Fan, but found that this guy started again.

One hand is holding a book, and the other hand is flipping through another book······

Nima, the world of learning God is so difficult to understand...·····

Fang Yifan couldn't help but speak: "Hey, Chen Fan, don't you hurry up and do the question?" ”

Chen Fan: "... The emperor is not in a hurry, and the eunuch is in a hurry. ”

When he said this, Chen Fan looked at him

Fang Yifan: "......"

I shouldn't have asked!

As everyone knows, Chen Fan took an anchor team behind his back and advanced to the king race!

go without saying

Kill all sides!

"Chen Fan, hurry up, they all want to defeat you."

As soon as Fang Yifan's words fell, he heard Qiao Yingzi raise his hand neatly:

"Teacher, I'm done!"

Li Meng nodded with satisfaction, thinking to herself, worthy of you, my math class representative!

motioned to Qiao Yingzi to go to the blackboard and write out the answer.

Qiao Yingzi stepped forward and didn't forget to glance at Chen Fan proudly.

emmm, my brother is busy with something else!

"Ouch, our family Yingzi is so powerful, Chen Fan finally won this small competition."

Fang Yifan happily looked at Qiao Yingzi, who was putting the answer out of the table.

Small races?

Your Yingzi?

Fang Yifan, are you healed and forgot the pain!

Chen Fan glanced up at Fang Yifan

Secretly said: Is this product that I have given him too many good faces recently?

Fortunately, after Fang Yifan spoke, Qiao Yingzi retorted: "Who is your family!! Fang Yifan, pay attention to what you say!! ”

Fang Yifan: "......"

！！

But he also woke up instantly!

It seems that the two of them are no longer behind each other at noon today!

And he just said such ambiguous words, turned his head and found that Chen Fan was also looking at him......

It's over, I'm going to be miserable!

In fact, Chen Fan was no longer angry when Qiao Yingzi refuted Fang Yifan.

Chen Fan glanced at the title on the blackboard

The answer has already appeared in my mind

96

But he didn't speak, because it was his own daughter-in-law who went up!

Li Meng began to write down the next question

3 boys and 3 girls a total of 6 students stand in a row, if boy A does not stand at both ends, and only two girls are adjacent to each other among the 3 girls, then how many different arrangements are there?

“288。”

As soon as Li Meng put away his pen, Chen Fan's faint voice sounded.

The students were slightly stunned, but they were not as surprised as in the previous physics class.

They thought that Chen Fan still memorized all the questions in his high school textbook as before.

If you have a good memory, you are comfortable, and you don't have to think about it when you do a topic.

The students are very envious!

Li Meng smiled helplessly, no wonder I saw the physics teacher who liked to ask questions in class in the morning with an autistic look······

She's almost a little autistic now, too.

The teacher's questions can't help but make it difficult for students! Say it and laugh off your big teeth!

I don't feel a sense of accomplishment at all!

Li Meng thought, gritted his silver teeth, and wrote an even more difficult question on the blackboard. The result is just halfway through the write-up!

But only halfway through writing, Chen Fan's brain was running rapidly, and he had already guessed what he was going to ask!

Chen Fan directly broke out the answer:

“x=-3，y=9!”

Li Meng: "......"

Nima, don't you force the old lady?

Li Meng, who was shocked, also fought back at this moment and wrote a calculus question directly on the blackboard:

f(1)=3, g(1)=5, f(1)=2, g(1)=4, when F(x)=f(x)g(x), find the value of F(1)?

It can't be calculated right away!

The students below are all blinded

Knowing is knowing everything, but how to count?

The next second that made Li Meng collapse came!

Chen Fan spoke directly, as if he hadn't thought about it:

“22”

Li Meng was a little anxious

Li Meng's mouth opened slightly, she was unwilling to come up with another one, but this time Li Meng learned to be obedient, and she came up with a simple question, but the amount of calculation was very large.

She writes a random number on the blackboard: **, find the 13th root of this number!

The classmates were dumbfounded, this is considered a pen

It's impossible to calculate! Fang Yifan directly took out the calculator and pressed it wildly.

But before he could finish pressing, Chen Fan's voice sounded again:

“5.**7！”

“.....”

Everyone was stunned!

Li Meng is autistic!

spoke: "Chen Fan, worthy of being the winner of the Fields Medal, I don't need to teach anything in mathematics anymore!" I'll allow you to read Chinese in math class! ”

Chen Fan: "......"

Students: "! ”

The whole class was in an uproar, is this still the Li Tie stick they know?

Chen Fan, you give me back Li Tieba!
