Guo Jia, the ghost of the strongest military division

Chapter 78 Mental Calculation
This……

Cai Yan also figured out the answer now, and she looked at Guo Jia in surprise.

This question was very difficult for her, and she would not have gotten the answer if it wasn't for Naimei's help.

How did Guo Jia get it?
Could it be that he really calculated it with his heart?
This bastard!

Cai Yu looked at the result with mixed surprise.

In fact, she didn't need to look at the answer, she already knew that what Guo Jia said was correct.

Because at this moment, her father's face is full of shock, and that Gu Yong's face is ashamed.

Can't it?
Gu Yong trembled and roared angrily: "You must have peeked at my answer, otherwise how could you answer it?"

It must have been accidentally seen by this guy when I was doing the calculations.

It must be so!
His face was no longer as gentle as before, but had become extremely ferocious.

From Gu Yong's mind, there may be someone who can calculate the chicken and rabbit in the same cage faster than him, but no one can figure it out mentally.

This is absolutely impossible.

Cough!

Only then did Cai Yong react.

Although Guo Jia's answer was correct, he didn't believe it was Guo Jia's mental calculation.

"In that case, Guo Jia, tell everyone how you calculated."

Not bad!

It was only now that Gu Yong came to his senses.

The answer can be copied, but the process cannot be copied.

If Guo Jia can't tell the process, it still means that his answer is copied from himself.

poor guy!

Guo Jia shook his head helplessly.

Although Gu Yong is in this era, arithmetic can be regarded as a top talent.

But there is no comparison with Guo Jia, a latecomer.

You must know that the difference between them is thousands of years of civilization!
Originally, Guo Jia didn't really want to attack the arithmetic talents of this era, but this fellow dared to rob Cai Meimei from him.

It's true that the uncle can bear and the aunt can't bear.

"This question is very simple. It doesn't need to be so troublesome at all. It's too incompetent to use calculation chips."

Guo Jia said with a smile.

Every time he said a word, Gu Yong's face turned darker.

Doesn't this bastard say that he is too imbecile?
Outrageous!

Gu Yong secretly swears that if this guy can't tell the reason, he will definitely not give up with him.

"Guo Jia!"

Cai Yong was also a little unhappy.

This guy actually said that the problem is simple, and those who use calculations to calculate are low-energy, so what is he who can't calculate with calculations?
Cough!

Guo Jia coughed a few times, and said slowly: "This is a simple problem of chickens and rabbits sharing the same cage."

"It's not a chicken, it's a pheasant!"

Cai Yong reminded.

"it's the same!"

郭嘉笑了笑, 继续道：“已知道两个条件，一个是鸡和兔子有35个头。另一个是鸡和兔子共有94支脚。假设鸡的数目是x，假设兔子的数目是y。X加y等于35。2x加4y等于94。解出来就是x等于23，y等于12。”

Cai Yong: ...

Gu Yong: ...

Sister Cai Yan: ...

sorry!
Guo Jia couldn't help wiping off his cold sweat.

It got complicated by accident.

People in this era don't understand binary equations at all.

Cough!

He coughed a few times in a hurry and said, "Let me explain in a way that you can understand. There are 35 chickens and rabbits in total, and 94 legs in total. Assuming that these 35 are all chickens, there are 94 legs in total. There is still a distance from the original 34 feet. We can use a rabbit instead of a chicken. 68 chickens are 72 feet, plus a rabbit with four feet is 33. 66 chickens are 74 feet, plus The eight feet of the last two rabbits is 23... Similarly, 46 chickens have 48 feet, plus the 94 feet of twelve rabbits, the two add up to exactly 23 feet. That is to say, the chicken is [-], and the rabbit is twelve."

Hearing Guo Jia's explanation, Cai Yong suddenly realized, Gu Yong was dumbfounded, and the Cai family sisters even smiled.

It turns out that there is such a simple solution in the world.

Even Cai Yu, who has the worst foundation in arithmetic, can easily solve it.

According to Guo Jia's solution, there is no need to count at all.

In other words, he really figured it out by himself.

"Wonderful theory, high theory!"

Cai Yong couldn't help applauding.

Although he still doesn't like this guy, he is still shocked by Guo Jia's novel and simple solution.

He never expected that this Guo Jia could not only establish a school in calligraphy, but also be unique in calligraphy.

This……

Gu Yong's face was pale.

He has been practicing arithmetic for many years, but in the end he is not as fast as others.

People can solve the problem with only oral calculations, but he actually has to use calculations for a long time.

It is clear at a glance who is higher and who is better.

"You are opportunistic!"

Gu Yong gritted his teeth and said.

Guo Jia's method of solving problems is unheard of, and it is not mentioned even in Jiuzhang Arithmetic.

In his opinion, this is Ye Luzi, not an orthodox arithmetic.

Opportunity?

Guo Jia sneered and said, "What do you want?"

Change the subject?
Gu Yong said unwillingly.

He didn't believe that after studying arithmetic for so many years, he couldn't compare to Guo Jia, who was born in a wild way?
very good!

Guo Jia nodded.

Since this guy doesn't know how to flatter, then he won't be polite.

"How about this, I propose a problem, if you can figure it out in a stick of incense time, how about I lose?"

Guo Jia said with a smile.

Gu Yong pondered for a while, then suddenly said: "If you come up with a problem that you can't solve in a short time, wouldn't I be doomed?"

do not worry!
Guo Jia still smiled and said: "It won't be too difficult. I can find a newcomer to teach a few words, and he can figure it out."

asshole!

Gu Yong was really angry this time.

"Okay, you make a question!"

He didn't believe that after studying for so many years, he couldn't compare to a rookie in academic calculations.

listen!
Guo Jia coughed.

"My question is, you accumulate from the beginning, and one of them accumulates to one hundred."

From one to one hundred!
Gu Yong hesitated for a while, but also felt that it was not a problem.

He returned to his seat at the moment, and while he was writing, he was fiddling with calculations.

Guo Jia sat down leisurely again.

At this time, my sister-in-law Cai Yu came up again.

"Guo Jia, the questions you gave are not very good. They are much simpler than the previous ones."

Cai Yu asked puzzledly.

Do not worry!
Guo Jia smiled slightly, squinted at Gu Yong who was serious about solving problems, and snorted coldly.

"With this guy's speed and the time it takes for a stick of incense, it's not bad if he can count half of it."

Doesn't this bastard look down on skills?

Guo Jia is going to give him some stimulation this time.

Thousands of years of civilization gap.

Hehe, it is not so easy to catch up.

After saying this, the guy went to sleep leisurely again.

Didn't take it seriously at all.

This bastard!

Although Cai Yu cursed secretly, she still admired her very much.

Unexpectedly, this guy is also so good at arithmetic.

Three times, five divisions and two divisions put Gu Yong on the ground.

She was waiting to see what happened next.
