A genius? I just love studying.

Chapter 14 Mathematics Can't Be Fake
"I'm Chen Hui's classmate."

Everyone's attention was instantly focused on him, and Yu Chuhao suddenly felt tremendous pressure. He was already sweating profusely and his clothes were soaked, but there was a sense of courage in his heart that supported him to continue speaking.

"This Chen Hui always fails math tests. He only scored 90 points in the math exam at the beginning of this semester!"

He emphasized Chen Hui's results in the opening exam.

"But just a few days ago, Teacher An handed out two sets of test papers he created himself, and Chen Hui got full marks on each one."

"Today, he once again came up with this difficult problem that stumped several of the team's experts."

"How come his math skills have improved so much in such a short time?"

"Why is this?"

Yu Chuhao looked at An Chengzhang. At this moment, he felt like a lone hero speaking up for the people, bravely standing up to uncover the dark truth for his classmates.

"Because Teacher An wants him to get a scholarship!"

“It’s a second-class scholarship!”

Yu Chuhao pointed his finger directly at An Chengzhang.

He understood, he understood everything. He found the answer to the question Li Hai asked him in the cafeteria.

Yes, what are the benefits of Chen Hui and Teacher An cheating?

Isn’t the benefit just this second-class scholarship!

All the logic is closed, Yu Chuhao is extremely sure of his guess, this is the fact!

Thinking of Li Hai's arrogant look and asking him to shut up, he suddenly became furious and stood up without hesitation.

The students in Class 7 outside the classroom suddenly understood.

Although this speculation involves their respected teacher An, considering what has happened recently, it seems that only Yu Chuhao's explanation makes sense.

Rather than believing that a person's math level has improved dramatically in a short period of time, they are more likely to believe that there is an ulterior motive behind this.

So all these things happened just to build momentum for Chen Hui to get the scholarship?!
What a painstaking effort!

Some classmates looked at An Chengzhang and Chen Hui, and their eyes changed drastically.

Some people even suspected that Chen Hui was An Chengzhang's illegitimate son. Although such a thing was outrageous in this era, it seemed very reasonable.

Many of them actually had no objection to Chen Hui receiving the scholarship. After all, they knew how difficult it was for Chen Hui's family. Although it was not legal, they could just turn a blind eye and let it go.

But they cannot stand being treated like fools, and they cannot accept that someone gets a scholarship by cheating. That is an insult to all of them, the students who study hard.

They will never accept it!

Students from other classes looked into the classroom and exclaimed in excitement.

They all knew Chen Hui, but now it seemed that the diligent and hardworking persona that guy usually portrayed in marketing was probably just an act, right?

After all, if a normal person works so hard, even if he can't get first place in the grade, his grades shouldn't be too bad, right?

Even Liang Peixuan's eyes flashed with confusion.

He knew Chen Hui and he thought Chen Hui was not that kind of person.

He respected Teacher An, and he didn't think Teacher An would be such a person.

But how do I explain what is happening before my eyes?
Zhao Defeng's expression also changed.

He thought of the test paper An Chengzhang gave him. At this moment, even he thought that what the unfamiliar classmate said was right.

Old An is so confused!

Even if he applied for a scholarship directly, his classmates would only make a few criticisms in the end. After all, Chen Hui's family was indeed in financial difficulty, so it was understandable.

But now we have done so many unnecessary things, which makes it difficult to finish.
But what he cares about now is no longer whether this matter is right or wrong. With the development of self-media nowadays, if this matter is exposed, it will be a huge disaster for the reputation of their No. 2 Middle School.

For him, it was a devastating disaster.

I glanced outside the classroom and saw that some classmates had already taken out their phones to take pictures.

He did not confiscate his classmates' cell phones. This kind of thing could definitely not be suppressed.

Zhao Defeng's brain was working rapidly, thinking about how to resolve this crisis.

Even Tan Junjie, who initially raised the question, looked at An Chengzhang on the podium in confusion. He hadn't expected things to get this far. He didn't believe that Teacher An was that kind of person, but the facts forced him to believe it, and even made him more certain of his suspicions.

Only members of the math competition team like them will be exposed to college mathematics. Ordinary high school students cannot even understand high school knowledge, so it is impossible for them to have the energy to self-study college mathematics.

After experiencing the initial anger, An Chengzhang calmed down.

He knew that he had not colluded with Chen Hui and had not told Chen Hui the answer, so he now believed more that the answer was made by Chen Hui himself.

As long as Chen Hui is really capable, there is nothing to worry about the current situation.

You can't fake math!

It is also the easiest to prove your mathematical ability.

If someone spreads rumors about other things, it may not be easy to prove your innocence, but mathematics can.

"Second-class scholarship?"

Chen Hui was stunned. Didn’t Teacher An say it was a third-class scholarship? How did it become second-class?
However, judging by the time, the scholarship list should be out soon, and I think my classmates have already seen the list.

Four thousand became eight thousand, and Chen Hui's heart was still full of surprise.

However, the list is still under public display, and there have been changes in the personnel on the list in the past. Now it seems that he still needs to do something to keep his name firmly on the list!

Chen Hui glanced at Yu Chuhao. He didn't remember any conflicts between him and this classmate. He didn't even have much impression of this classmate.

Apart from studying, he rarely pays attention to other things and does not have much interaction with other classmates, so naturally he will not make enemies with them.

But none of this matters.

He didn't panic from beginning to end. People with confidence won't panic.

While everyone was questioning and angry, he had quietly walked to the podium.

When someone questions your math ability, you just need to stand up and solve all the math problems they give you!
Take, take, take…

The sound of chalk rubbing against the blackboard could be heard.

The sound woke everyone up from their emotions and they all looked towards the blackboard.

"When did he get to the blackboard?"

"What is he going to do?"

"He's not really going to do the questions, is he?"

At this moment, absurd emotions arose in everyone's hearts again.

But they all fell silent. No matter what Chen Hui was going to do, they would soon know the answer.

Tan Junjie frowned, "That's impossible! He hasn't studied college math. How could he actually solve this problem?"

Yu Chuhao widened his eyes again, standing blankly in the classroom like a goose, with a bad premonition in his heart becoming stronger and stronger.

Given that x+y+z=1, x≤y≤z, find the expectation of x.

After converting the question into mathematical language, Chen Hui wrote a big word "Solution" on the blackboard.

It is known that x≤y.

Since y≤z, so x+2y≤1.
Chen Hui moved a little to the right and randomly drew two horizontal and vertical lines to establish a two-dimensional coordinate system. He then drew the straight lines x+2y=1 and y=x in the coordinate system, and marked the origin of the coordinate system as O, the intersection of x+2y=1 and the y-axis as B, and the intersection of the two straight lines as C.

It is easy to find that the two straight lines intersect at (1/3, 1/3).

After hesitating for a moment, Chen Hui erased the two words "easy to get", then combined the two straight line expressions to calculate the coordinates of the intersection.

Obviously, the expectation of x and y is the center of gravity of triangle OBC.

According to the properties of the center of gravity, the center of gravity is located at 2/3 of the line connecting the vertex and the midpoint of the opposite side.

The result is G (1/9, 5/18).

所以最短边x的期望为1/9，次短边期望为5/18，最长边期望为11/18.
After writing the answer, Chen Hui turned around, threw the chalk on the desk, and looked at everyone in the classroom.

At this moment, everything is silent.
