At this time, Chen Ze'an smiled and said: "Your Majesty, the grass people are brave and want to fight for a chance for Brother Wang!" ”

Chu Yuanqi said noncommittally: "How do you want to fight for it?" ”

"I'll solve this problem for him!"

As soon as these words came out, the ministers all looked at Chen Ze'an like fools.

In their opinion, whoever solves this problem is the same, and instead of sticking to this problem, it is better to seize their own opportunities.

Who knew that Chen Ze'an continued: "If I can't solve this problem within a cup of tea, I will voluntarily give up the opportunity to become an official in the court."

But if I solve it, I also ask Your Majesty to give Brother Wang a chance. ”

Chu Yuanqi looked at Han Du with a look of irrelevance, "Since this question is from the horse, then the horse is in charge...... What does the colt think? ”

Han Du already felt guilty about Wang Yong, and now Chen Ze'an blocked his opportunity, which made him sigh......

But Chu Yuanqi still wanted to ask his opinion, Han Du sighed and said: "It is impossible to solve this problem within a cup of tea, it is a matter of the future, it is better for the little brother not to be rash." ”

What he didn't know was that Chen Ze'an was thinking in his heart: If you want to talk about the future, if he goes back to the mountain col to continue teaching and help his mother take care of the weaving workshop, will there be no future?

These people thought they wanted to come.

If it weren't for the sake of angering Brother Wang, he wouldn't have opened this mouth!

But Chen Ze'an didn't show it on his face, and said in a calm tone: "Thank you for your concern, but most of Brother Wang's arithmetic is taught by me, and I know his ability very well."

With enough time, he will be able to solve this problem, but he doesn't want to delay our time.

I'm sure many of you here are like this, and you must be too, right?

It's just that time is precious, so instead of bothering the horse master to solve the problem himself, it's better for me to give it a try.

It's just a cup of tea, but it doesn't work, and it can't delay anything, right? ”

When Han Du heard that he was going to let him solve the problem, his face changed slightly......

Chu Yuanqi watched this scene for a long time without saying a word.

It wasn't until Han Du had to nod that Chu Yuanqi said, "Then I will give you a cup of tea, if you don't solve it, it's no wonder that others." ”

"Thank you, Your Majesty."

I saw Chen Ze'an walk to the stage, picked up the pen that Wang Yong put down, and wrote freely on the desk in front of him......

Jiang Yao asked Jiang Yu in a low voice, "Have you taught them this question?" ”

She has the impression that this kind of problem was learned in junior high school before, as if she wanted to list a system of equations, can Chen Ze'an really solve it?

Jiang Yu shook his head and said, "I didn't teach them...... But I told the children in the children's class about the problem of chickens and rabbits in the same cage. ”

"Children's Class ???" Jiang Yao was puzzled, "Can they understand?" ”

"Naturally, I can understand, I teach the simplest way to lift my feet, and the numbers used are also very small, so I can solve three problems in one cup of tea...... Hey? Didn't Ze'an listen to Sanxi and them? "Quite possibly......

"Foot lift?"

Jiang Yu rarely saw Jiang Yao confused, and said with a smile: "There are also things you don't know!" See, this is called a specialization in the art industry......

This is a common topic in the Primary School Mathematics Olympiad, and there are many ways to do it, but I think the easiest is to lift your feet......

However, what Sanxi and they do is as simple as "five heads and ten legs".

The amount of calculation for Han Du's question was too big for Ze'an.

So I gave Mr. Feng that their question set doesn't have this one......"

Jiang Yu said and looked at the stage curiously......

Chen Ze'an's brush on the stage is non-stop, and there is no need to stop and think......

It's just that he didn't use an abacus, but drew a brocade diagram on paper......

"Huh?" Jiang Yu was a little surprised, and muttered in a low voice: "Isn't this the same as lattice multiplication in modern mathematics?" ”

But she didn't teach them either......

This grid multiplication is like another representation of the vertical form of multiplication.

And look at Ze'an's algorithm...... It's really a foot lift......

If this is the case, don't talk about solving one problem with that cup of tea, it is not difficult to solve three problems faster.

Jiang Yu suddenly calmed down, took another pastry from the table, and ate it......

In the eyes of everyone, I saw that the pen in Chen Ze'an's hand didn't stop for a moment, and it seemed to be drawing something for a while......

Xie Yu frowned slightly, and thought: Isn't this person pretending to be a ghost, and is ready to write an answer casually to get by?

He still didn't believe that this man could solve the problem.

But with so many people present, it's not easy to calculate correctly, but it's still possible to calculate an answer.

Let's see what tricks he has up his sleeve......

Soon, in the eyes of everyone who were either skeptical or curious, Chen Ze'an stopped his pen and said aloud to everyone: "Today, there are pheasants and rabbits in the same cage, with ninety-seven on the top and three hundred feet on the bottom, forty-four pheasants and fifty-three rabbits. ”

Everyone was in an uproar: it was really calculated?!

Han Du didn't know where to get the abacus, and his fingers flew......

Looking at the results on the abacus, Han Du muttered in disbelief: "That's right!" Really figured it out?! ”

"How did you figure it out?!" Han Du stepped forward excitedly.

Jiang Yu, who watched it with relish at the top, suddenly sat up straight, thinking: It's coming, it's coming! The highlight moment of the spike is coming! I've really grown a lot!

Jiang Yu sighed with emotion.

Jiang Yao next to her noticed Jiang Yu's small movements, and glanced at her silently: This look is really unchanged if it doesn't look like it's a big deal......

Still, it's worth seeing......

I saw Chen Ze'an smile lightly: "If you want to talk about this method, it was told to me by a child in our village who was less than ten years old......

The crowd looked sideways, but most of them didn't believe it.

For example, Xie Yu, such as Han Du.

Just kidding, they didn't come up with a method, how could a child under ten years old think of it.

This kid must be talking nonsense.

And Chen Ze'an, who was talking serious nonsense, had already thrown his sleeves off, turned his back to his back and said: "Suppose that the pheasant rabbits in the cage are all raised on two legs......

Then ninety-seven heads, a total of one hundred and ninety-four feet.

Three hundred feet raised one hundred and ninety-four feet, and only one hundred and six feet remained in the ground.

At this time, the pheasant is suspended in the air and the rabbit stands on both feet.

One hundred and six legs are all rabbit feet, so there are fifty-three rabbits and forty-four pheasants in the cage. ”

For a while, the audience was silent......

Xie Yu and Han Du looked at Chen Ze'an on the stage dumbfounded, their minds racing over Chen Ze'an's words, trying to find a loophole......

But no!

Logically, this idea does solve this problem.

At this time, Han Du strode forward and walked towards Chen Ze'an on the stage.

Chen Ze'an looked at Han Du who was coming violently, subconsciously took a step back, and said in his heart: Did you pretend to be too much and provoke the anger of the public?

Chen Ze'an subconsciously looked at Jiang Yao and Jiang Yu who were sitting at the top, his heart suddenly settled, and he even quietly prepared for battle.

Sister Xiao Yu said: Don't cause trouble when you go out, but you can't be afraid of things.

If the enemy does not move, I will not move, if the enemy moves, I will move first!

This Han Du's little body, he still doesn't care about it......
