Chapter 29
【205495】
Kong Xuan wrote his answer at the end of the question.
Xu Zihan was stunned.
She thought that this question was too difficult for Kong Xuan.
He couldn't answer.
Unexpectedly.
At the last minute.
Kong Xuan actually figured it out.
As for whether it is correct or not.
Lin Xuerou picked up the calculator for the first time and started calculating.
He is also a graduate of an ordinary university.
Lin Xuerou couldn't figure out this question in 30 seconds.
So she didn't know if Kong Xuan was right.
Although I hope my boyfriend's answer is right.
But her gut told her it was unlikely.
How can ordinary people have this mental arithmetic ability.
Not to mention the multiplication of three digits.
Even two digits have to be counted for half a day.
To know.
Each additional digit.
The difficulty is all increasing exponentially.
But when she pressed the numbers on the calculator.
When you see the results.
Instantly opened his mouth in surprise.
Then she looked at her boyfriend incredulously.
The answer is actually right!
Everyone else in the room looked at each other.
It's a bit of a surprise.
Xu Zihan's father, Xu Feng, looked at Kong Xuan appreciatively and nodded.
"Humph!".
"You're in luck!".
In Xu Zihan's opinion.
This guy does have some strength.
But that's not all.
She could see the embarrassed expression just now.
It almost ran out of time.
It is estimated that it was also a last-minute cloud.
Just right.
The point is.
You're struggling to count three digits.
Then how do you count if you add it later?
Kong Xuan pretended to be shocked.
When you see the result calculated by the calculator.
A long sigh of relief.
Then he arched his hand towards Xu Zihan.
said: "Accept and concede." "
Xu Zihan glanced at him with disgust.
"Alright. "
"Let's get the question out of now!".
Kong Xuan smiled.
Pick up the pen.
Wrote down the third question - [366X564].
The number on the question is only a little larger than the previous one.
Kong Xuan naturally wanted to see the strength of this girl.
Who knew that Xu Zihan rolled his eyes.
Don't look down on me.
There was no hesitation at all.
I put pen to paper and wrote down the answer.
【206424】
Lin Xuerou once again confirmed the result on the calculator.
Then it was announced: "The answer is correct. "
Kong Xuan nodded.
Complimented:
"Not bad. "
"Count faster than me!".
Xu Zihan glanced at him.
Heartway.
If you don't count it soon, I won't mess around.
Next.
It was her turn to ask the fourth question.
At this point, she was a little entangled.
Is it directly difficult to defeat Kong Xuan directly?
Or give him another sweetness.
And then give him the fatal blow when he is most proud?
It seems that this is more programmatic.
She pondered for a moment.
The second option was chosen.
Write the fourth question on the manuscript paper - [34231-86793].
For the first time.
She directly raised the number to five digits.
But the notation of the operation becomes subtraction.
So in fact, the difficulty is reduced.
But for ordinary people, it's still not easy to do mental arithmetic.
Because it's a decimal minus a large number.
And every bit counts.
All of them have to "borrow" the previous single digit.
You need to "borrow" five times in a row!
Ordinary people may "borrow" the second time and their brains will be messed up.
Not to mention "borrowing" five times.
- "Good fellow, I'm dizzy when I look at such a string of numbers. "
- "Although the number has increased a lot, the difficulty has actually decreased. "
- "That's right, the difficulty of addition, subtraction and multiplication and division is not of an order of magnitude at all. "
- "Although I am dizzy when I look at this question, if I am given enough time, I can calculate it, but the three-digit multiplication by three-digit number just now, I can't figure it out if I am killed." "
- "Yes, the multiplication of three digits is beyond the limits of ordinary people's mental arithmetic. "
- "Oh, no, it shouldn't be possible for the little girl not to realize this, why did she take the initiative to reduce the difficulty?".
- "Didn't you see the difficult appearance of the protagonist when he was calculating the problem just now? I must have wanted to play more and have more show effects!".
- "Indeed, after all, for her, it is five digits by five digits, and she can also blurt out the answer." "
- "Hahaha, poor protagonist, going to be played like a monkey!".
The moment I saw the subtraction problem.
Kong Xuan also had similar doubts as netizens.
How can this be made less difficult?
But he didn't know Xu Zihan's true identity.
So take it for granted.
It's this little girl's immature mind.
It's harder to think that more numbers are more difficult.
So I couldn't help but shake my head.
The answer was quickly written.
Subsequently.
It was his turn.
Of course, he didn't want to take advantage of others.
So a similar subtraction problem came up.
Xu Zihan also quickly wrote the correct answer.
By this time.
Kong Xuan could also see it.
The little girl definitely has a good talent in mental arithmetic.
has even gained a lot of fame by relying on this skill.
Otherwise, I wouldn't have come up and compared myself with mathematics.
He always looks proud and conceited.
These mental arithmetic questions are currently out.
It's not too difficult, though.
But it's not the kind that ordinary people can see the answer at a glance.
And this little girl.
Just one glance at a time.
Write the answer in no time.
It is enough to show that its mental arithmetic ability surpasses most people.
So he thought to himself.
The next time the question comes out.
You'll have to think about making it more difficult.
Let's see how good this little girl is.
And just when he thought so.
Xu Zihan took the lead in increasing the difficulty for him.
Question 6.
Xu Zihan is a division problem.
【777888÷999666】
Netizens took a look.
Directly blinded.
Boy.
Six digits divided by six digits!
This kind of question.
Don't talk about ordinary people.
Even college students have a headache when they look at it.
Don't talk about mental arithmetic.
Even on paper, it has to be counted for half a day!
