At this time, Chu You couldn't help but sneer: "Our students are all picking up people's teeth, according to Brother Gongsun, shouldn't we all work behind closed doors, shouldn't we listen to the teacher's lectures, and shouldn't read books?!" ”

Du Zhong also said: "Brother Gongsun is strong. ”

Gongsun Hong was furious, but he didn't dare to attack because of his identity, so he had to say fiercely: "Don't be too happy, it's time for the Hou Ye to ask the question!" ”

Tang Qi smiled slightly: "It just so happens that I also have a simple question, if you are interested, you can do it and take a look." ”

Chickens and rabbits in the same cage is a fun question after all, and it is similar to a brain teaser.

The test is on-the-spot reaction and logical thinking, and the reason is very simple, and there is no problem of not understanding it.

In later generations, from elementary school to university, there were countless variations of similar problems.

The difficulty is also increasing.

The original version of the chicken and rabbit in the same cage, placed in the compulsory education of later generations, has long been reduced to the point that it can only show its face in the extracurricular extension of primary school mathematics, and even the smarter primary school students are not stumped.

In the junior high school textbook in Tang Qi's warehouse, there happens to be a similar topic.

Du Zhong said: "Please ask Mr. to make a question!" ”

The other students also became serious, and asked the shopkeeper for cloth and pen and ink to prepare for the question.

An Dinghou said that this question is not only for Du Zhong, but also for all the students here, who wants to answer it.

To put it another way, if you can't do this problem, it's everyone who will be disgraced!

Although Du Zhong is a recognized mathematical genius in Taixue, at this time, it is not good that he is really the only one to answer, right?

Even Gongsun Chong, who didn't know anything about logarithms, held the pen with a black face and pretended to hold the pen.

There are already dogs around to prepare, and when Tang Qi comes up with the question, they will "help" Gongsun Chong to answer the question as quickly as possible.

You can't really disgrace the prime minister's grandson, right?

"Listen up!"

"It takes 8 hours to fill a pool with water and 20 hours to fill it up. Q: How long does it take to fill up if I fill up with water while releasing water? ”

“……”

The room was silent.

Tang Qi was satisfied to see that everyone's faces, including Du Zhong, were full of confusion.

In later generations, the problem of pond water injection that tortured countless middle school students was put into the Wudi Dynasty, and the lethality increased exponentially in geometric multiples!

You must know that these students are too students, but they may not even be able to calculate the original version of chickens and rabbits in the same cage!

What to use to inject water and release water to ask questions is simply a dimensionality reduction blow!

Now whether it is Du Zhong, or Chu You, Gongsun Chong and his dogs, or even the onlookers, scholars, family sons, and rangers.

The eyeballs began to draw circles, and the same sentence was written on their faces.

Who am I, where am I, what am I doing?

What fills water and releases water, what 8 hours and 20 hours, what the hell pool is so tormenting!

Can't you inject water and release water, why do you have to be together!

Come on, cut down the person who poured water and released the water!

At this time, in the hearts of countless people, the above sentence couldn't help flashing, and there was murder in their eyes.

Tang Qi sat down leisurely, enjoying the street view of Chang'an Avenue while enjoying the strong smell of boiled tea in the Han Dynasty.

Honestly, it doesn't taste good at all.

It's a little bit better than the mare's milk wine I've tried in Kamiya-gun.

It's time for stir-fried tea!

Hey, how much do tea tree seeds cost?

In front of everyone's eyes, the students racked their brains to try to clear their minds, but the culprit Tang Qi began to leisurely "go to the supermarket".

Well......

It doesn't seem to be expensive, and the tea making method is okay.

It's decided, give Dahan Department Store a new one!

Time passed little by little, and when Tang Qi had read all the tea tree seeds and introductions in the "supermarket", the surroundings were still quiet and could smell the pins falling.

Looking up, half of them were still thinking and struggling, and half of them were glaring at Tang Qi.

What a problem!

I've never seen it in the scriptures, and people are dizzy when they go around!

Especially the grandson, holding the pen and sweating like rain, that look can't wait to eat the question's life!

Tang Qi smiled inwardly.

I knew that this was the result.

Modern people stand on the shoulders of giants, with a modern mathematical system built since childhood, and it is easy to turn around when they suddenly encounter the problem of pools.

What's more, the development of mathematics is still in the early stage, what about the ancients thousands of years ago?

After waiting for another hour, the sky gradually darkened, and Du Zhong finally sighed: "The student really can't figure it out, and I hope that Mr. will advise." ”

"Whew-"

Everyone breathed a sigh of relief and quickly put down their pens.

I was thinking hard before, but I really couldn't put it down.

Now that even Du Zhong, a genius in mathematics, has admitted defeat, then it is not a shame for them to admit defeat again!

So everyone said in unison.

"Please sir!"

Gongsun Chong also reluctantly followed and said, "Please advise sir." ”

Tang Qi raised his eyebrows, he didn't expect this kid to bow his head?

Knowing that it is easy to ask questions in school, it seems that he is not a hopeless person, so why did he target himself before?

Forget it, whatever, maybe it's the second second.

Tang Qi shook his head and directly threw his doubts out of the clouds.

Anyway, there are more lice and it doesn't itch, and there are more people who don't like it in the middle.

Left and right are too lazy to mix with officialdom, what about them!

"This question, to put it bluntly, is actually very simple. As long as it is clear, even a newly enlightened child can solve it. ”

Tang Qi asked the shopkeeper to come and hold the sand, spread it on the table, and use the branches as pens.

It's too troublesome to write formulas with a brush, and although the sand table is a little shabby, it's practical.

Unconsciously what he said provoked the anger of the public!

The students were red-faced, and they didn't dare to let the people see their faces clearly.

Children can answer, doesn't that mean that these students are not even as good as children?!

I want to be angry, but in the end, my skills are not as good as others, and I can only hold back.

But the answer still has to be heard.

Anger is anger, and it does not prevent everyone from pricking up their ears and listening carefully.

"First, we can set an unknown number X, uh, no, unknown 'none'."

Tang Qi first wrote an x, and then realized that this was in the Western Han Dynasty, so he changed it to "nothing", anyway, the meaning is on the line, and the symbol comes casually.

"Once the unknowns are set, let's assume that it will take 'no' hours to fill up with water......"

Up and down the teahouse, for a while, there was only Tang Qi's eloquent voice.

In the early days of the Han Dynasty, official learning was still in its infancy, and most of the knowledge and knowledge were in the hands of the high families and relied on the inheritance of family learning.

If ordinary children want to study, it is more difficult than crossing a single-plank bridge with thousands of troops.

Only the best talented sons of good families are likely to be favored by the elders of the family and study with their teachers.

And in this era, the so-called one-day teacher and lifelong father, apprenticeship, is actually tantamount to selling oneself.

No matter whether he can become an official in the future or not, he will not be able to get rid of the influence of the division commander for the rest of his life.

Even in Taixue, the doctors, who are teachers, will not know everything and say everything, but more often talk about things that are full of clouds and fog.

What's more, there is also a school dispute, and the learning environment of the students is actually not good.

Therefore, as long as Tang Qi said that the sound family could not be passed on, and only gave an answer without teaching how to calculate, no one could criticize him in this era.

But Tang Qi didn't have this consciousness at all, just like lecturing for his younger brothers and sisters in his previous life, he broke it and talked seriously.

For many students, this gesture alone is enough to make them grateful!
