After a deep breath, Xu Hui asked, "At thirty miles apart, I and I come out of the towns of each town. You go east and south. I don't know how many steps you go out. They all go northeast to the town. You meet with me. If you ask you to do five, I go three, how much will you do? How much will you do?"

This is an extremely advanced calculation problem in contemporary times.

It not only involves mathematics, but also geometry!

It is difficult to understand, and it cannot be counted by everyone.

After hearing this, Zhang Yue moved the abacus in his hand two or three times, then raised his head and replied, "I went south for 2,400 steps, and northeast for 1,4662 and a half steps to meet you, and you took 2,932 and a half steps..."

This question is too challenging and difficult for Zhang Yue.

Just know that the Han Dynasty has three hundred steps in one mile.

This question is a free score.

It can be done if you change to junior high school students.

After hearing this, Xu Hui's face changed suddenly. This was a rather difficult arithmetic problem in his father's "Xu Shang Arithmetic".

He once relied on this to rush north.

Even if someone can solve it, it will take at least a few days to achieve it!

However, the young man in front of him had solved the problem in just a moment!

How is this possible?

Xu Hui gritted his teeth, bit his tongue, and said ruthlessly: "There is a mountain living in the west of the tree. I don't know how high it is. The mountain goes 53 miles away, the tree is nine feet high, and the tree is nine feet high, and the tree is three miles east of the tree. Look at the tree is level with the peak, and the person's eyes are seven feet high. How high is the mountain?"

Another geometry problem!

In the Han Dynasty, geometric mathematics is the pinnacle of the crown of mathematics.

Generally speaking, all the mathematicians regard geometric calculations as their tireless research direction.

Geometric mathematics is also widely used in many aspects such as land statistics, land acre calculation, fortress construction, channel construction, water conservancy engineering, etc.

Since Wenhou of Peking, scholars all over the world have focused on studying geometry.

And the question Xu Hui has put forward is indeed awkward.

The nobles around him fell into deep thought when they heard this.

If they could find a solution to the question just now, then they wouldn't even know how to start this question.

Xu Hui was even more proud.

This question was one of the obstacles his father encountered when studying Nine Chapters of Arithmetic.

After three years of hard thinking, I gained something.

He doesn't believe it!

This mere poor scholar in Changshui Township, Nanling County can still calculate it!!!

"The mountain is 164 feet and 9 feet and 6 inches high, and half an inch left..." Zhang Yue straightened his abacus and looked at Xu Hui and said, "I have already said that, don't waste my time! Let's go together!"

"Even if I beat you up with a group of people…"

"You!" Xu Hui's angry hair was about to stand up!

But he still couldn't have an attack.

Xu Hui finally understood why Mencius had a great loss of grace in the debate between Mr. Xu Xing in Qi and finally blurted out: "The rapist in the Southern Barbarians also tells the way of the previous kings?"

There is no way, I can't argue, I can only curse people!

The others were even more angry.

Are you awesome?

But there is no need to humiliate people like this, right?

How do you get along in the future?

But they completely forgot that not long ago, they were thinking about using Zhang Yue as a stepping stone.

…………………………………………

The onlookers were stunned at this moment.

"Is this life capable of ghosts and gods?" The son of a marquis bit his tongue, unable to believe what he saw and heard in his eyes and ears.

In his twentieth year, he was against several talents of the world?

The last time such a person appeared in the Han family, it was traced back to more than 60 years ago, when Jia Yi and Jia Changsha emerged and dominated the world.

At the age of eighteen, he fought against the scholars in Henan County alone, and at the age of twenty-four, he made the world bow down.

"Is it another Jia Changsha?" someone murmured to himself.

Jia Yi and Jia Changsha died young.

But he left an immortal mark on the Han literary world and Shilin.

The influence has not dissipated to this day.

Who has not learned from Jia Changsha’s style and narrative methods of the scholars all over the world?

And this guy is even more exaggerated!

He is in the field of mathematics and surpasses the talents of the world!

And it seems that I haven't used all my strength yet!

This is too exaggerated!

Jia Yi and Jia Changsha are just well-written and knowledgeable.

After all, he is just a scholar, at best he is just an aide.

And a good math person...

With his unparalleled mathematical skills and superhuman political skills, Wenhou of Peiping assisted Emperor Taizong Xiaowen for fifteen years and pulled the Han family out of the abyss of decline, chaos and poverty!

When he was the prime minister, the Huns roamed between Henan.

All nations are trapped in water and fire.

The three dukes and nine ministers of the court even had to take over the ox cart when they went to court.

The country's army was hungry on the frontier, and some soldiers couldn't stand it anymore, so they used tree bark to fill their stomachs and even filled their stomachs with clay.

When he leaves the phase.

In the imperial treasury, grain and copper coins were piled up like mountains.

There are even ropes for strings of money that rot in the treasury.

The frontier army had sufficient food and clothing, and the Han army even began to form a local force to contain the Hun cavalry.

The people live and work in peace, and the world's merchants and wealthy people emerge one after another.

There are rich businessmen and even rich slaves who are planned by thousands of people, and they are comparable to kings and princes when traveling!

The country has even begun to have the strength to prepare for the construction of ranches and accumulate horses in the north!

Even the ministers of good mathematics in this world are all important officials of the country.

The most obvious example is the chief master Sang Hongyang.

Don’t look at countless Confucian scholars yelling every day: Please cook Hongyang!

It seems that Sang Hongyang will not die, and the country will be in peace!

But... as long as anyone with a brain knows, the Han family has been able to persist in the long war of using troops to foreign countries for years and spending countless times and has not yet collapsed.

It all depends on Sang Hongyang and his salt and iron yamen.

Without salt and iron income, the national finance has long collapsed!

"I heard that this person has not been married yet?" Someone's eyes rolled and he immediately had an idea in his heart: "I have Xiaojun, so I should be married to this person!"

If such a talented person who is hidden in the abyss is not able to find a way to bring him into his home, then these nobles will have been in vain for so many years.

Even Yuan Chang was shocked.

"What this guy said is true..." He opened his mouth wide and looked incredible.

Then, he clapped his hands.

"This is so cool..."

"This kind of pretentious posture is so beautiful..."

"I want to learn too..."

yes……

Compared to Zhang Zizhong, he used to be too low to show off by relying on wealth and followers.

Look at them!

This action shocked the audience, and everyone's eyes were full of respect.

If I could do this too...

Isn't that much more fun than it is now?

No, at least it’s 10,000 times more fun!

……………………………………

Xu Hui looked at the scholars around him, and then at the noble son of the Yuan family behind him.

In my heart, I almost fell into a state of despair.

He knew very well that what happened today would definitely be spread.

From then on, his Xu Hui's name was directly linked to this Zhang Zizhong.

When others mention him, they will say: Xu Hui, I know, isn’t it the Taiyuan scholar who was easily beaten by Zhang Zizhong?

This reputation is not good at all, and it will seriously affect his future career!

Completely destroy the path of generals and ministers he had planned long ago!

what to do?

How to recover this disadvantage?

Xu Huisi thought about it all over and over, and he felt that if he had made up the so-called difficult questions, he might just make fun of him.

If Zhang Zizhong is broken by this casually, where will his face be put?

Suddenly, a flash of lightning broke through Xu Hui's mind.

"It's it!" Xu Hui clenched his fists.

Xu Hui believes that Zhang Zizhong will definitely not be able to answer this question!

Even if he is a god, he can't answer it!

Because this question has troubled Chinese mathematicians for decades, countless powerful giants have been studying for their lives, but they ended up regretting!

He squatted down, drew a circle on the ground, then raised his head and asked, "Can you solve this question?"

"I hope Zhang Sheng can give it to the ratio of the circle!"

Pi!

The immortal crown of geometry!

At least that's the case now!

Since Zhou Ren Jing proposed the conclusion that the conclusion was made on Wednesday, for hundreds of years, countless people with lofty ideals and geniuses and powerful people have been competing to devote themselves to their efforts.

Everyone knows that the conclusion of the calculating scriptures is wrong.

but……

No one can calculate a value that is more accurate than the circumference calculation.

No one can even find a better calculation method than the periphery.

As a result, Pi has become an eternal pain for mathematicians all over the world for hundreds of years.

Everyone knows that Zhou Ren's calculation is wrong.

But no one can give an accurate answer.

There is not even an approximate answer!

Xu Hui didn't believe it!

This poor scholar from Nanling can give the answer!

If possible...

So……

If you lose in the hands of an unparalleled genius who solves Pi, you will be convinced.

When you go out in the future, you don’t have to worry about being pointed at.

After all, losing to passers-by is a shame.

But losing to Dong Zi and beard is a supreme honor!

not to mention……

Xu Hui never believed that the young man in front of him could solve it, and he could solve it!

Zhang Yue looked at the circle, looked at Xu Hui again, and suddenly burst into laughter: "Pi... so coincidental, I just happen to know..."

“Three, one, four…”

"If you want a more detailed answer... it is 3:1415926..."

In later generations, this is probably the answer that elementary school students can also memorize.

"Impossible!" Xu Hui shook his head suddenly, and he felt that the whole world was collapsing.

"You are lying!" Wu Yuan shouted.

Pi, this is a problem that has troubled digital artists all over the world for hundreds of years!

The crown of the field of mathematics!

Undoubted throne!

"Why is this impossible?" Zhang Yue said with a smile: "When I was twelve years old, I had already accurately measured the pi to 3.14..."

Well, that year, the history textbook did tell him the answer.

"When I was eighteen years old, I had already accurately answered this answer to 3:1416..."

"A few days ago, I got three:1415926..."

"There is more precise later, I just don't bother to ask..."

"Don't you believe me?" Zhang Yue stood up, walked to Xu Hui, squatted down, and said, "Then I will tell you, how did this answer come from?"

"Round cutting technique..."

"Cut the circle continuously, cut it again and again, and finally you can't cut it again. You get one hundred and ninety-two parts. If you find it according to the Pythagorean theorem, you get three or four..."

"If you have free time, continue to cut it, and then cut it to 1,536 sides, and get a pi of 3:1416..."

Everyone heard it incredible.

Xu Hui even had a severe rupture in his liver and gallbladder.

Because he found that the other party’s method was right and feasible!

only……

Who would be so bored that he would constantly cut edges and divide equally in a circle?

And such a job must be extremely boring and tiring.

"Afterwards, I thought this was too boring and too boring, so I found two values..."

"So divide these two values ​​into two to get three points, one four, one five, nine sixty two..."

"These two numbers are three hundred and fifty-five and one hundred and three..."

"I call it with my secret..."

Standing up, Zhang Yue looked at Xu Hui and asked, "How about my round-cutting technique and secret rate?"

Xu Hui was already stunned and even provoked.

Such a solution, such an algorithm.

Although he hadn't calculated it, he knew that such a method must be feasible! It must be feasible!

This shows that what the young man in front of him is right.

He didn't lie!

He solved the pi and answered the questions of countless sages over the past hundreds of years.

Xu Hui took a deep breath and slowly took three steps back. However, he longed and bowed, and bowed again, saying, "Zhang Jun is a great righteousness to solve the doubts of the world, Hui worships the world!"

If you don’t accept it, you won’t be able to!

In today's world, if anyone can figure out pi, he will definitely become famous all over the world!

Because, pi is the crown of mathematics!
Chapter completed!
