As the camera zooms in.

People watching the live stream.

I also saw the title written by Xu Zihan on the manuscript paper.

Where is this a topic for elementary school students?

It is a problem for finding a differential equation.

Calculus?

Okay!

Feelings: This is a sophomore college topic!

In the studio.

Luo Wan'er frowned exquisitely.

Calculus ...... Looks like I studied it in college, right?"

She has a university diploma.

But it's been a few years since I graduated.

Spend all day singing your mind.

I've forgotten all about that.

Cheng Hai, who is also a big star, is even more confused.

He debuted early.

And learned acting very early.

Naturally, the academic qualifications are not high.

The term calculus is unheard of.

Among the guests on the field.

Only the young business star Fan Liming is a veritable scholar.

So he could see it at a glance.

This question is indeed a course that only the sophomore year of college takes.

"If I'm not mistaken. "

"This little sister is the champion of a junior intelligence draft. "

"But I remember. "

"It doesn't seem to have any math problems of this level in that talent show, right?"

Netizens in the live broadcast room are also discussing this issue.

- "Talent show, of course, it's impossible to test any advanced math problems. "

- "Yes, the little sister won the championship at that time with her unparalleled mental arithmetic ability. "

- "It seems that we still underestimate this girl, and she even knows math in college!".

- "If you look at it this way, it's actually okay, it's not that difficult. "

- "It's fine for college students, but it's hard for people who have graduated for a few years. "

- "Hahaha, that's right, just graduated two years ago, and all the university knowledge has been returned to the teacher!".

- "But I don't think this question should be a problem for the main character. "

- "I also think that looking at his performance in front of him, it doesn't feel like a big problem. "

As a matter of fact.

For Kong Xuan.

It's really not a big problem.

After all, on the virtual panel in front of him.

In the skill bar marked with the word "Mathematics".

It shows that the level is as high as 99!

That is, the full level.

Don't talk about calculus.

It's Goldbach's conjecture.

He worked hard.

It can also give you a clear understanding.

It's just that he was very surprised.

Such a seven or eight-year-old kid.

How do you write advanced math questions at your fingertips?

"Sister Zihan. "

"This question...... Where did you look?".

Xu Zihan tilted his head.

With tsundere said:

"I came out of it myself. "

Kong Xuan wrinkled his nose.

"Little sister. "

"Lying is not a good habit. "

Xu Zihan listened.

Qi said: "I didn't lie!".

In fact.

Although the program team invited her to test Kong Xuan.

But these topics did come up with them on her own.

As a gifted child who has been known as a genius child who has not met in 50 years.

Not only does she have a super memory and mental arithmetic skills.

His talent in mathematics is also beyond the reach of most people.

But Kong Xuan didn't believe it.

Do you have a system that can't be done?

But he doesn't want to be too embarrassed, little girl.

Just laughed and said, "Do you know the answer?".

"Of course I do!".

Kong Xuan nodded.

Took the pen.

Start writing your answers on paper.

He writes fast.

It's even faster than Xu Zihan writing the question just now.

It doesn't seem to be necessary to think at all.

Boom.

Just under fifteen seconds.

The whole process of solving the problem has appeared on the paper.

Xu Zihan frowned and looked at it.

He glanced at Kong Xuan suspiciously.

If you didn't know that this was a tricky show.

She wondered if Kong Xuan had peeked at the answer in advance.

It's too fast!

Although the topic itself is not profound.

But it also belongs to the more complex category.

Why don't you pretend to think about it.

As a sign of respect for me, hey!

Thereupon.

In Xu Zihan's heart.

Kong Xuan's image suddenly changed.

I like the kind of pretending ratio.

This.

It's very similar to how she positions herself.

Of course.

She likes to pretend.

It's about being confident that you're a genius.

And for her.

Kong Xuan likes to pretend.

It's just a simple outfit.

This annoyed her.

At the same time, it also aroused her competitive desire.

Kong Xuan looked at her immature little face with a change of expression.

I couldn't guess what this little girl was thinking for a while.

So he asked:

"How?".

"Am I writing right?".

Behold.

Xu Zihan snorted.

"Surely you've read books on this lately. "

"I'll give you another hard debut!".

"You can't answer that. "

Kong Xuan pointed to the manuscript paper in disbelief.

"Are you sure I'm right?".

"You don't just look at the results. "

"It also depends on the process of solving the problem. "

"Why don't you take out the answer and match it. "

Kong Xuan thought she had seen the final result.

After all, the process of solving the problem is relatively complex.

How could her little head remember it?

Xu Zihan gave him a blank look.

He

pointed to his head angrily.

The answers are here. "

This surprised Kong Xuan.

Boy.

It turned out that I underestimated this girl.

Such a complicated step can be remembered.

He spread his hands.

"Okay. "

"Then you move on. "

"I'll try again. "

The little girl didn't say anything.

Silently wrote again on another piece of manuscript paper.

This.

She was cautious.

Didn't come up with the questions yourself.

After all.

She couldn't be more talented in math.

Age is here.

The level of math can't really be exaggerated.

So.

Again.

She didn't go as planned.

Rather, there was one.

Former International Mathematics Olympiad titles.

This question has been selected as one of the top 10 IMO problems.

After writing the question.

Her smug little eyes looked at Kong Xuan.

It seems to be saying.

I still don't believe it.

It's up to you how you solve this problem.

After all.

The first time she did this question.

It took a whole day to come up with an idea.

Kong Xuan took the manuscript paper.

I looked at it.

He nodded approvingly.

Well.

This question is indeed more difficult than the one just now.

If the calculus question is a second-grade question.

That's an algebra problem.

I think it's a third grade, right?
