I am the king of the dead

Chapter 265 In arithmetic, continue the past and forge the future

Wu Jing devoted his whole life to arithmetic, so naturally he was not ambiguous. He finished this arithmetic paper in less than three quarters of an hour.

In his opinion, this math paper is moderately difficult and not very embarrassing, but it is definitely not a paper that can be answered easily.

Before Zhu Qiyu became emperor, he was a teacher, and a math teacher at that.

He takes numbers very seriously.

What is the level of this paper?

At most, it can be regarded as the level of the second year of junior high school, but it involves a lot of realistic topics.

For example, the ancient question: There are things that do not know their number, three or three leave two, five or five leave three, seven or seven leave two.Ask about geometry?
How to answer?

The poem says: Three people walk together for [-] years, five trees have [-] plum blossoms, and the seven sons are reunited in the first half of the moon, and you will know when you divide one hundred and five.

It means that the first remainder is multiplied by 70, the second remainder is multiplied by 21, the third remainder is multiplied by 15, and finally divided by 105, the remainder is the result.

（2×70+3×21+2×15）÷105=2……23。

The core logic of this question is the remainder theorem. Zhu Qiyu does not require students to give a complete proof process, but will answer this question.

This kind of question is very simple, and there are detailed answers in "Sunzi Suanjing" and "Nine Chapters of Shushu" Volumes [-] and [-] "Da Yanlei" in the Southern and Northern Dynasties.

Does Zhu Qiyu have nothing to do?

What is the use of this kind of congruence or different remainder problem?
In reality, it is not used at all.

Of course, Zhu Qiyu was not bored, making it difficult for candidates.

It is because the remainder theorem is completely an important branch of basic mathematics - the content of an elementary introduction to number theory.

Zhu Qiyu wanted to find scholars who were dedicated to mathematics, and even had a certain ability to sum up, so as to promote the progress of mathematics in Ming Dynasty.

Basic mathematics is a science that specializes in the study of mathematics itself, and does not aim at any practical application. It studies the mathematical laws abstracted from the objective world and explores the nature of the world.

The talents that Zhu Qiyu wanted were talents who could take Daming's mathematics a step further.

He looked at the despondent students and heaved a heavy sigh. They are all the dragons and phoenixes of the Ming Dynasty. Their articles are written very well. They may have extremely high moral and academic standards, but it does not mean that they can do well. local officials.

In fact, this is not surprising.

Daming's officialdom is more like a Gu pot for the Miao people, and they only officially started raising Gu after the imperial examinations.

Some guys with little ability can write articles no matter how good they are. For example, Zeng Heling, the number one scholar in Yongle for 19 years, and Liu Ju, the second place in the list, are not very capable people. They can only write articles in the Imperial Academy for the rest of their lives.

After Zhu Qiyu glanced around, he suddenly saw Wu Jing in a daze, to be precise, he looked like he was doing nothing after finishing the questions.

Of course Wu Jing was very respectful, he was sitting upright all the time, but he was obviously distracted.

Hu Wei kept his eyes on his nose, and his nose seemed to be falling asleep. He raised his head and saw that His Majesty was watching Wu Jing. Then he briefly glanced at Wu Jing, and he seemed to be asleep again.

But Hu Yi has already imprinted Wu Jing in his heart.

Jiang Yuan looked at the time and rang the small copper bell for collecting the papers. Seventeen examiners sorted the papers into different categories and sent them to the imperial court under their names.

"The exam is over, and the tributes are leaving the palace." Chen Xun shouted loudly.

The palace examination was finally over, and Wenyuan Pavilion did not feel too much pressure this time. His Majesty would only send the examination paper back to Wenyuan Pavilion after reading it once.

His Majesty directly accepted the examination papers of mathematics, but Wenyuan Pavilion.

"Farewell to Your Majesty." The officials and tributes saluted and sent Zhu Qiyu away. The invigilator sat for at least four hours, and His Majesty was obviously tired with twelve crowns on his head.

A layer of cold sweat suddenly broke out on Wu Jing's forehead. As His Majesty got closer and closer to the gate of Fengtian Palace, the sweat on his forehead became more and more intense. His expression changed very complicated and quickly. Stomp, grit your teeth, and get out.

Wu Jing shouted loudly: "Your Majesty, Cao Min has a scroll to offer in front of the gate!"

Zhu Qiyu had just stepped out of the Fengtian Hall, and the two palace servants behind him were holding the policy questionnaire and the math paper.

Zhu Qiyu retracted his feet, and said kindly: "Oh, what is it?"

He has been observing Wu Jing who has already finished answering the test papers, obviously he has already finished, and he is repeatedly weighing something.

Wu Jing was very nervous. This is Daming's Fengtian Hall, the sacred artifact of the Ming Dynasty, and the place he yearned for the most in the past 30 years, because this is where the official artifacts of the Ming Dynasty are located.

This is where the heaven of the Ming Dynasty is in essence, and in the hearts of all scholars, this is their holy temple!

They studied hard in the cold window, under the faint lampstand, under the bright moonlight, after countless tossings and turns, they came to the capital, came to this Fengtian hall, and finally became a tribute.

It is very likely that he will not be able to pass the exam and needs to be dispatched as an official. It is very likely that he will never see His Majesty again after the Luming Banquet.

He exhausted his whole life's energy, spent ten years of hard work, and finally completed a masterpiece, but he could only turn it over occasionally, lamenting and complaining.

The Ming Dynasty used the Four Books and Five Classics to obtain officials. Therefore, ordinary scholars regard mathematics research as a daunting path, and even think it is a deviant thing.

Wu Jing didn't want to see his energy go to waste, he bet on his official career, under the watchful eye of Wenyuange University scholar and Liubu Minggong, he suddenly spoke.

How much courage is needed for this sound?
Since arriving in the capital, he has heard too many rumors about His Majesty, and he is willing to give it a try.

Establishing a heart for the world, establishing a life for the living and the people, inheriting the knowledge of the past, and creating peace for all generations are the supreme pursuit of scholars.

At this time, he could only see His Majesty's rather heroic side face, and he seemed to be curious and relieved.

He said nervously: "Your Majesty, I have ten volumes of the book "Nine Chapters Algorithm and Analogy Encyclopedia", dedicated to Your Majesty."

Zhu Qiyu frowned, then slowly turned around and asked, "What's your name?"

He realized it was a big fish.

Wu Jing bowed his head and said, "Wu Jing is from Renhe, Zhejiang."

Zhu Qiyu understood, it really was a big fish!
Hu Wei suddenly opened his eyes, grabbed his sleeves and trousers, took two steps and said: "Your Majesty, most of the world's great talents are proud of their talents, and it is the same for Wu Jing."

"There is a poem that says: Mountains are never too high, seas are never too deep, the Duke of Zhou spit and feed, and the world returns to his heart. In the past, there was a Duke of Zhou who washed his hair three times and fed three times with one meal. He was afraid of losing the people of the world!"

This poem is "Duan Ge Xing" by Cao Cao. The Duke of Zhou is the fourth son of King Wen of Zhou.

Hu Wei had no idea that Wu Jing would act so boldly, calling the Emperor of Ming to stop him.

He doesn't know, is His Majesty willing to kill people?

Who is Your Majesty most wary of?

Naturally, it was the bureaucrats of Ming Dynasty. His Majesty threw the Beijing officials into the mansion, and he had to pump water every year to see which fish didn't want to live.

Taking the imperial examination, in Fengtian Hall, there was a loud roar, and a scholar who had just finished the imperial examination called out to His Majesty the Emperor!

This incident caused all the courtiers to break out in a layer of cold sweat immediately. The imperial examination, the selection of officials for the country, how could such disrespectful people be selected?

Hu Mi's brow was sweating anxiously, Yu Qian was not in the capital, and he was not good at persuading Renshu, but Chen Xun was not good at it.

Just as he was about to speak, he saw His Majesty turned around with a smile still on his face.

Zhu Qiyu waved his hand to signal Hu Min to step back, he looked at Wu Jing and said: "Since the book is presented, Hu Shangshu, take someone to bring the book to Tai'an Palace."

"Okay, I've been taking the exam for a whole day, and I'm waiting for the grand ceremony of passing on to you."

"Wu Jing, right, very good."

Zhu Qiyu has always liked people with backbone. No matter what the person's status is, people with backbone generally have good morals.

The officials breathed a sigh of relief, His Majesty did not blame Wu Jing for his disobedience.

Zhu Qiyu turned around again, couldn't help showing a smile on his face, and strode out of Fengtian Hall. If the officials were not watching, he would have laughed three times.

There were many mathematicians in the Ming Dynasty, and Wu Jing happened to be a mathematician who was underappreciated. He devoted himself to inheriting the past and opening up the future of mathematics, and sorted out the mathematics of the past dynasties.

"Nine Chapters Algorithm Comparison Encyclopedia" is a summary of past mathematics and an exploration of future directions.

Link the above and below.

But this book is the same as Wu Jing, because of the constant party disputes in the court during the Jingtai period, the pearl was dusted.

Now this bright pearl rolled in front of Zhu Qiyu, still shining, as if to say again, quickly pick me up!

When is Fisherman the happiest?
Time to catch a giant!
Zhu Qiyu took a deep breath, and left Fengtian Hall step by step. The more he walked, the happier he was, and there was such unexpected joy.

The book Wu Jing wanted to present was quickly sent to Tai'an Palace by the Ministry of Rites; Wang Zhi, Minister of the Ministry of Officials, used the fastest speed to obtain Wu Jing's past experience in land taxation in Zhejiang;

The Ministry of Punishment looked through the files in Zhejiang and confirmed that Wu Jing was just an ordinary scholar and had no criminal record for rape;
The household department urgently calculated the account book of Wu Jing's land tax conversion back then, and was convinced that this person was not a corrupt person who broke the law.

Wang Wen found several censors of Zhejiang Province and asked them to conduct an urgent inspection of Wu Jing's past as an official in Zhejiang.

Only Shi Pu, Shangshu of the Ministry of Industry, looked at the busy people and said with emotion: busy, everyone is busy.

Among the six ministries, Yu Qian, Minister of the Ministry of War, went to oversee the army in Kyushu outside the mountains, and it seems that only the Ministry of Industry is useless to His Majesty.

Before evening, Shi Pu, Shangshu of the Ministry of Industry, was called to Tai'an Palace.

Zhu Qiyu was grading the math test papers, and they were full of writing. Several candidates used math problems as application essays and wrote long speeches.

It is not complicated to correct, more than 150 papers are counted, and the correction is completed in a short time.

"See Your Majesty, is Your Majesty blessed?" Shi Pu saluted respectfully.

Zhu Qiyu smiled and said, "An, give me a seat."

"I'm looking for Shi Shangshu, there are ten volumes, to see if it is useful for the construction of the Ministry of Industry."

Ten volumes have been opened and read.

This book is all-encompassing, including Fangtian, Corn, Decline, Shaoguang, Shanggong, Junshu, Insufficiency, Equation, and Pythagoras. Each volume is composed of three parts: ancient questions, poems, and analogies.

Ancient questions, of course, are all kinds of ancient questions;
Poetry is a generalization of a common problem-solving thinking in Ming Dynasty, just like poetry for solving remainder problems;
Analogy is Daming's current problem, and it involves everything that one expects to find.

The last volume of Wu Jing's book is the extraction of the past and the future, including the extraction of the square, the extraction of the cube, the extraction of the higher power, the extraction of the square and the extraction of the cube.

It belongs to the category of pure mathematics research.

Zhu Qiyu couldn't put it down for these ten volumes, but he still had to do the review work. After he finished the review, he still needed to give it to the cabinet. This matter could not be sloppy at all.

This is a major event for the national Shilin cake distribution, and it is not easy to delay.

Shi Pu looked at it for a long time and said, "Your Majesty, can you take it back and take a look at it, it seems that there is a curfew."

The last time Gu Yao resisted the edict and insisted on going to Taibailou to have a drink after the curfew, which was fine, and he even arrogantly told the people from Wucheng Bingma Division that he was from the Metropolitan Procuratorate.

The grass on the graves of the three of Gu Yao was three feet high.

Shi Pu is also a respectful person, so naturally he will not violate the curfew.

Zhu Qiyu smiled and said: "As long as it is useful, I have already asked the Sanjing Factory to engrave the block. After a month, these ten volumes can be printed on a large scale."

"Of course, you can also use movable type to print the book first, print a few copies, and let the officials have a look first."

Zhu Qiyu has always had a headache about how to improve the calculation ability of Jixing.

Although he has a textbook of "Arithmetic", it is for the illiterate rural people, and at best it can be regarded as rudimentary.

He has always planned to write a mathematics textbook for the eunuchs and eunuchs of Ji Province.

But he is indeed very busy, with national and family affairs and world affairs, and he started writing several times, but he was delayed because of some things.

The ready-made textbooks are now placed in front of Zhu Qiyu, and they are extremely mature.

It was Wu Jing who spent the past ten years in Zhejiang calculating the taxation of farmland, what he saw and thought, and almost wrote down what the entire Ming Dynasty needed most.

Zhu Qiyu said with a smile: "I plan to take another course in the lecture hall, which is mathematics, but before that, let Wu Jing go to the Imperial Academy as Wen Linlang, and be in charge of the lectures on mathematics in the Imperial Academy."

"Xing'an, remember it, and remind me later, don't let me forget."

Xing'an took out the memo from his sleeve, brushed a few strokes, and wrote it out.

Shi Pu looked at the ten volumes of books, he was also a scholar, of course he knew what these ten volumes meant, but His Majesty said that engraving and printing would be required, so he had to wait.

"I congratulate Your Majesty, and congratulate Daming!" Shi Pu showed a look of embarrassment, looking at the few volumes of books, a little bit unwilling, but still bowed his head and said: "Your Majesty will leave."

The Ministry of Industry that Shi Pu brought was at the end of the sixth part, so he still left the study, even if he scratched his head again, he would have to wait for His Majesty to print it out before he could get a glimpse of the whole picture.

Zhu Qiyu has already finished grading the calculation papers, except for Wu Jing, all of them failed...

Mathematics is a late learning in Ming Dynasty, but it doesn't matter.

He is the emperor, as long as he gives an order, the students in the Guozijian who have nothing to do all day will have to learn this thing and have to take the exam.

Cows don't drink water?Pressing the head forcibly is, the twisted melon is indeed not sweet, but it quenches thirst.

How many students does Guozijian have?

More than nine thousand names.

This is not what surprised Zhu Qiyu the most, what made him gratified was the courage of the students of the Ming Dynasty.

Zhu Qiyu's reputation as a murderer is known to everyone from North Korea to Timur.

But Wu Jing stood up today and expressed his thoughts loudly, although there were only a few short sentences, and it was dedicated to the book.

But this still represents the righteousness of Daming Shilin, and there is still an extremely meager trace.

If this trace of righteousness is properly guided, Daming Shilin may become better.

In fact, it is not surprising, after all, to have a courtier like Yu Qian shows that the Ming Dynasty is still upright.

The lights in Tai'an Palace were brightly lit, and Zhu Qiyu was seriously studying and judging the questionnaires. Zhu Qiyu would draw "O" or "X" on the questionnaires. The more O's you drew, the more in line with Zhu Qiyu's wishes.

Zhu Qiyu didn't care about anything else, but mainly cared about their buttocks and which side they sat on.

Fengtian Hall, Fengtian Yiyun, is where the country's public treasures are located, so you can't find a bunch of people who don't know how to sit in it.

Wang Meilin came over to take a look, sighed, and told Xing'an a few words, telling His Majesty not to stay up too late and go to bed earlier.

Your Majesty who is busy with state affairs, of course, is of great benefit to everyone in Daming but not harmful.

But the four beautiful and beautiful girls in the palace suffered, and the palace resentment, how sad.

Compete for favor?

Your Majesty can't even see you, how can you fight?
