Zhang Ji looked at the thirteen masters sitting in front of him. Pen "Fun" Pavilion www.biquge.info

These great craftsmen, all of whom are covered with smoke and dust, are the filth of working by the fire or between the woods all year round, and over time, they are deposited into the skin and cannot be washed away.

What's more important is that they have physical disabilities, more or less, and some even have facial features.

Such a person, in the past, would not have been able to appear in this Xuanshu Palace, let alone be respected by the Son of Heaven.

"I haven't heard of anything like a good man since ancient times...... Zhang Ji thought to himself.

The Han dynasty is a dynasty that looks at faces.

Before the accession to the throne today, from top to bottom, one looked at morality, two looked at behavior, and three looked at appearance.

looks bad, let alone being an official, a knife and pen official will not let people be!

can only go to the market and mix with the three religions and nine streams.

Handsome and personable scholars are the characters who are respected and admired by the people, and they are the pillars of the country's society!

But......

Since his accession to the throne, the system has gradually disintegrated into invisibility.

The appearance is the first in the world, and the big farmer who can be called the willow under the Hui in the world is undoubted, and he was born lowly, and his appearance was barely counted to go to the business to look overhead, and he became a shopkeeper.

The old minister, Yuan Si, who was also famous for his appearance, demeanor and fame, was even simply driven out of Chang'an, and now he has been reduced to South Vietnam to educate Yidi.

It's sad to think about!

At the same time, all kinds of characters from the three religions and nine streams began to fill the temples and palaces.

Even, when today's think tank, Nalantai Shangshu, there are dozens of Qiangfu and Youfu who have been transferred from the local area.

Who are they?

The noblest born was only the son of a deceased county lieutenant.

As for the mud legs and the villagers, the number is not clear.

But, at least, these people still had a fig leaf in the past - they were all scholars, and they were all selected through the examination or probation system.

Now, however, the Son of Heaven intends to break this stereotype.

Tear off the last fig leaf of the reader.

This is naturally hard to accept.

Moreover, it makes people's hearts tingle.

Looking at the craftsmen in front of him, Zhang Ji thought in his heart for a while, and then, stepped forward, walked in front of a craftsman in his forties, who seemed to have lost two fingers, bowed to him politely, and then said: "Dare to ask Ming Gong: Today, there are five households with a total of one well, and the first two are insufficient (Note 1), such as B and one well, B and three are insufficient, such as C and Yi, C and four are insufficient, such as Ding Yi, Ding Wu is insufficient, such as Wu Yi, Wu Liu is insufficient, such as A and Yi. If they are less than a handful, they are all caught, ask the depth of the well, and the length of the well? ”

After saying this question, Zhang Ji looked at the craftsman in front of him triumphantly, quite a bit of a flying and domineering taste.

If it weren't for the Son of Heaven by his side, Zhang Ji even planned to provoke all the craftsmen in front of him.

"Humph!" Zhang Ji sneered in his heart: "This problem is a problem that not many people in Chang'an can do!" ”

This question comes from the fact that after sorting out the twelve chapters of the "Sutra of Calculation" dedicated by Zhang Cang, the Marquis of Beiping, the prince of Beiping, this question synthesized the arithmetic problems that have been circulated among the people, the court and the opposition and the court in the past dynasties.

Then, they are synthesized into a book, called: Counting Books.

There are 100 questions in the arithmetic.

This question is not the most difficult, but it is also at least in the top 20.

Zhang Ji had to calculate the book that year, and it took him a full month to solve the answer to this question.

After solving this problem, Zhang Ji spent the remaining month to solve all the rest.

And this matter has always been the greatest pride in his heart.

In Zhang Ji's eyes, in the whole world, the study of arithmetic is profound, how many people can compare with him?

……………………

Liu Che sat on the throne, and he was very familiar with this topic.

This is an example from Zhang Cang's writings.

And it is a complex equation that even in the future generations, I am afraid that ordinary junior high school students will not be able to solve it.

As for now?

It's really a top-notch topic in cutting-edge mathematics.

The people who can solve him, even in this court, are probably less than half.

As for eagerness, want to solve it?

Almost unlikely.

But......

Liu Che knew that this kind of topic, in front of these masters, was as simple as addition, subtraction, multiplication and division for elementary school students.

The reason is very simple - Liu Che has already opened the hangs for the craftsmen!

Arabic numerals, alphabetical equations.

Everything Liu Che can remember is taught.

And the craftsmen are not as good as the doctors, hypocritical and arrogant.

I won't say anything, these simple numbers and letters are humiliating to our predecessors and sages, let's use the old way and use the juxtaposition method to solve it!

So......

Liu Che closed his eyes and couldn't bear to look at the next scene.

But Zhang Ji is still complacent.

Although this topic is not a cutting-edge topic in the current Han Dynasty mathematics research, it is also a cutting-edge knowledge.

The nobles of the Feshi Doctor did not have the qualifications, the ability and the knowledge to solve it.

I don't know the equation (Note 2), and I don't know how to solve it.

Even geniuses need at least a year to touch the threshold!

Zhang Ji didn't believe it, these vulgar craftsmen could still solve such a problem?

As for why the open questions are used to test people?

This is actually out of Zhang Ji's careful thinking.

By repelling the craftsman with an open subject, he can show his open-mindedness and tolerance to the world: Look! I've given it a chance, but these craftsmen are just vulgar and unbearable, and it's hard to get into the hall of elegance!

Moreover, by the way, you can also show favor to the Son of Heaven - Your Majesty, the minister is already very face-saving, but the craftsman is rude, and the minister has no choice......

What's more, Zhang Ji is confident that he will win!

In his thinking and logic, such a topic is probably like a book from heaven for craftsmen!

Hugh said answered!

I'm afraid it's hard to figure out the meaning of the question!

After all, there is a specialization in the art industry.

This is like a mechanical metallurgical expert in later generations, taking a random topic is enough to discourage laymen and bow down.

It's like a music professor who casually plays a tune in front of the piano stand, and ordinary people can't even understand it.

This is the crushing of knowledge and the triumph of professionalism.

Therefore, Zhang Ji also had a leisurely and elegant appearance, pretending to be generous, and said: "If Ming Gong doesn't understand, I can say it again!" ”

In his heart, he felt that even if he said it again ten thousand times, the person on the other side would not be able to answer.

But......

In the next second, Zhang Ji heard a deep voice with a Shu County accent: "You don't need to say it anymore, the villain already knows the answer......

I saw that the craftsman in front of Zhang Ji stood up and bowed: "The answer is: the well is seven feet two feet and one inch deep." The armor is two feet six feet and five inches long. It is one foot nine feet and one inch long. It is one foot four feet eight inches long. Ding Fang is one zhang two feet nine inches long. It is seven feet six inches long......"

Zhang Ji was dumbfounded, and he couldn't even believe it.

Because the answer is exactly right! Perfectly!

How is this possible?

Zhang Ji couldn't believe his ears at all!

Just now, he still stubbornly thought in his heart that the craftsmen were vulgar and illiterate, but now, the facts slapped him hard, almost knocking him to the ground, his nose and face were swollen, and he couldn't help himself with embarrassment!

Zhang Ji took a deep breath, barely maintained his aristocratic demeanor as a scholar, and bowed for a long time: "Dare to ask where the equation is?" ”

He knew he had one last chance.

That's the equation.

In the era of mathematical governance pioneered by Wenhou of Beiping, many one-dimensional quadratic equations, as well as positive and negative equations and multivariate multiple equations, were solved by a unique equation in China.

This makes it easy for people to solve the difficult problems and problems encountered in the past to get a convenient, fast and understandable way to solve them.

But the problem is that even today, there are very few people who can master these equations.

With the exception of the princes and scholars, these equations were rarely outflowed.

Even when countless books on the subject have been printed today,

However, there are very few people who can afford these books, and even fewer who have the leisure and leisure to study these high-end mathematics.

And if the craftsman can't answer the equation, then there is no way to prove that he really answered the problem.

It can be denied that he is rote memorization and even a blind cat bumps into a dead mouse.

However, in the next moment, the craftsman smiled slightly and bowed: "Equation? If you want it, the villain should give it! ”

In an instant, the entire Xuanshu Hall was extremely silent.

All the ministers looked at the craftsman like monsters. (To be continued.) )
