Fang Hong received a call from his daughter Fang Yuanxin.

He dared to come to Shendong Middle School for the first time.

On the way here, he had verified in his mind countless times that 'the sum of the squares of two right-angled sides is equal to the square of the hypotenuse' and found that it was undoubtedly extraordinary, and all of them were correct.

This made him ecstatic when he first arrived.

You know, in the past, when they counted this kind of geometry, they directly applied the rule of hooking three strands, four mysteries, and five points.

But there are many rules that cannot be calculated. For example, how to calculate the sides of an isosceles right triangle.

This kind of problem can only be calculated by establishing a mathematical model, not to mention the complexity of the process, and the error is very large.

"Xin'er, do you remember what that person looks like?"

"Dad, I just remember him asking me for directions, as if he was asking the second class of the third grade."

Fang Yuanxin looked confused, she didn't have much interest in anything else except for her obsession with mathematics.

"Let's go to the second class of the third grade."

……

Fang Hong took his daughter to the window of the second class of the third grade.

"Dad, that's what the guy on the blackboard told me."

"Oh? It's that he is a junior high school student, but it's not like it, it's more than 1.7 meters. ”

in the classroom

Qi Chen's writing is like flowing water. As time passed, he wrote on the blackboard a variety of problem-solving methods.

A

Both

Three kinds

When Qi Chen wrote about the third type, Li Dan was already unaware. But she still firmly believes that there can't be six answers to this question.

However, when Qi Chen wrote four and began to write the fifth, Li Dan finally panicked, and her face turned blue and white for a while.

After writing the fifth type, Qi Chen began to write the sixth type.

Suddenly, the flustered Li Dan suddenly calmed down, and she was smiling.

She found that the latter two methods of solving the problem were completely made up, which was just a hard set of answers.

When can the hypotenuse of this right triangle be calculated like this?

How can such an equation be used here, it is completely chaotic.

Fu Xiaobai sat in front of the computer, and she was also calculating this problem.

But she only counted three methods, and she couldn't think of the rest anymore. She looked up at Qi Chen's focused appearance on the screen.

She couldn't help but be surprised and admired, she couldn't imagine that Yi Chen was so knowledgeable.

The live broadcast room is also quiet at the moment, and there is no barrage.

Finally, Qi Chen finally finished writing all the answers. He looked at the old witch triumphantly.

"Come, old witch, the blackboard brush for you. It's still hot. Eat it. ”

"Little brute, don't you laugh at me, you can write the answer in this mess?"

"Old witch, do you want to play tricks? Are you worthy of being a teacher? ”

"Little bastard, what do you say? I'm not worthy to be a teacher, people like you are worthy to be a teacher? Look at you, which teacher taught you to use the square of these two right-angled sides and the open root number to calculate the hypotenuse. Don't laugh at me. ”

Li Dan walked to the blackboard, pointed to the fifth calculation process, and said with a smug face.

Qi Chen's angry expression suddenly fell, he looked at the old witch strangely, and asked weakly

"You haven't heard of the Pythagorean theorem?"

"What bullshit theorem, don't mess around, get out of here."

Li Dan picked up the blackboard brush and had to erase the problem-solving process.

At this time, Fang Hong, who had been watching outside the classroom, pulled the girl into the classroom.

"Old woman, you can wipe it today."

He knocked out Li Dan's blackboard brush with one lunge, and his eyes looked at the fifth and sixth methods of solving the problem with fascination.

He had never heard of any of the formulas used in either method.

You know, he is a professor of mathematics, and he is the nominal vice principal of this Shendong Middle School.

"Old thing, who are you and what are you doing? Get the hell out of here. ”

Li Dan was furious, and today she broke into her classroom one by two, which made her feel that she had lost face in front of the students.

Fang Hong was disturbed by his thoughts, his face was full of unhappiness, and he turned back to look at Li Dan with a gloomy face.

"I am the vice principal of this school, and from now on, you are expelled. The notice of dismissal will notify you as soon as possible. Now, you're ready to roll. Shendong Middle School, a teacher like you who spews feces is not welcome. ”

When Li Dan saw the familiar face, he knew that something was wrong, and the next second he found out that he was expelled, and he immediately panicked.

"You can get out. I don't want to say it a second time. Fang Hong's face was full of disgust and disgust.

"You can't fire me, you don't have the right to fire me, my cousin is Li Feng, he won't agree to you firing me."

"Don't say that your cousin is Li Feng, even if your father is Li Gang, it's useless."

"You wait, you wait......"

Seeing that the students in the class were all looking at her strangely, Li Dan's face was ugly, so she could only go back first and call her cousin.

The fans in the live broadcast room were dumbfounded. What kind of unfolding is this, it's a bit out of pace.

[Anchor, anchor, what's the situation at the scene, why can't I understand it. 】

[I don't understand.] This is because the anchor pretended to be successful, didn't he just tell us that he wouldn't do it]

[That's right, how did you make six kinds at once, and the cow fork is made.] 】

[Could this new vice principal be the father of this little Lori? ] It's amazing, I have to find the anchor to be responsible. 】

[Anchor 666, could it be that you succeeded in flirting with your sister? ] I don't understand it. 】

……

Qi Chen also looked at Fang Hong and the glasses-wearing little Lori inexplicably.

"Hello, may I ask if the formula used in these two solution ideas was discovered by yourself?"

"Ah, you ask this Pythagorean theorem?"

"Is this called the Pythagorean theorem?"

Qi Chen was dumbfounded, and he hurriedly searched for the memory hard drive.

Sure enough, in the memory drive, a lot of knowledge about geometry is stored inside.

So, now on this abridged version of the online game Earth OL, there is no Pythagorean theorem?

Qi Chen couldn't cry or laugh, this online game system is too messy. There is no Pythagorean theorem, how can this geometry be developed?

"Sort of."

"Really? You're amazing. ”

"Vice principal, look, we're in the classroom, it's not good to talk about this."

"Yes, yes, I was negligent, then go to my office"

……

In the end, Qi Chen still didn't follow Fang Hong to his office. They exchanged phone numbers, and Qi Chen promised him to write a paper on the Pythagorean theorem in his name and publish it. After class, Qi Chen took Tong Xinyu and prepared to go home.

At this time, he had turned off the live broadcast.

"Qi Chen, thank you."

Tong Xinyu took the initiative to take Qi Chen's hand and said.

"Xiao Nizi, it's good if you don't torture me at home in the future, okay, brother will take you home."

Qi Chen was happy, although this girl still didn't want to call him brother, she was already willing to take the initiative to hold his hand, which was a big improvement.

"No, I'm going to the bar in the evening."

"What are you doing there? At a young age. Come home with me. ”

"No, Qi Chen, I'm going."

Tong Xinyu shook off Qi Chen's hand and pouted.

"Okay, okay. Then I'll go with you. ”

"Hmmm......"

Qi Chen pulled Tong Xinyu, found a random restaurant for dinner, and took Tong Xinyu to the bar she was going to.
