Northern Song Dynasty Revitalization Strategy

Chapter 457 A Math Problem That Everyone Says is Simple

"When the temperature drops, shouldn't the amount of rain be reduced? The Yanjing Mansion is almost flooded!" Zhao Huan sighed while looking at the rain outside the window.

The heavy rain poured down on the eaves, and the sound of ding ding dong dong was endless. The rain fell down the bricks and tiles, forming a rain curtain, and fell on the railing.

The small pond outside has been smashed into small blisters, and the lotus is standing firm with green leaves, welcoming the torrential summer rain.

[The drop in temperature is not directly related to the amount of rainfall. Affected by strong convective weather, there will be heavy rain in Yanjing City recently. Please bring rain gear when you go out. 】

Zhao Huan looked out the window helplessly, it was raining heavily, and even the large construction site in Yanjing City began to stop work, waiting for the rain to stop.

And Zhao Huan rarely rested for a few days.

The number of letters sent from Bianjing has become less, and there are not too many major events. It is that Bianjing City is preparing for the official examination recently.

Zhao Huan had no opinion on the exam questions. There was one question that he was not very good at, so after a little research, he cleared his mind.

"The Yangtze River absorbs many waters, and never turns back. The blue sea can accommodate Yangtao, and flows eastward day and night. This question is interesting." Zhao Huan scratched his head when he looked at the question.

Mathematics is a thing that is full of life, and it is all-encompassing. This group of students who take the official examination will suffer.

Zhao Huan tried to figure it out. This question is not difficult, but he just didn't remember it for a while.

Zhu Lian put a cup of tea on the table, saw Zhao Huan doing the math, and asked, "Officer, can I have a look?"

"Just take a look if you want to. The official exam is coming soon. It is the first official exam I have come to enthroned. It is a big deal, but these questions are all simple variants in the fourteen books of mathematics, so it is not difficult. "

Zhu Lian put down the teacup, leaned into Zhao Huan's arms, adjusted her body so that she could lie comfortably in the official's arms, and read the letter with her hand.

"The library has three colors of cloth, cotton, and wadding, and I want to make military uniforms based on materials."

"Its cloth: six people and eight horses are less than 160 horses, and seven people and nine horses are left with 560 feet."

"Its cotton: 150 taels for eight people, 500 taels left, 170 taels for nine people, 400 taels left."

"Qixu: 840 catties for four people, [-] catties less, [-] catties for five people, enough."

"Would you like to know the geometry of soldiers, cloth, cotton, and wadding?"

"It's a very simple double-set surplus problem. It's very simple." Zhu Lian smiled and said after reading the question.

Double-set surplus is actually the basic overall planning, which is mostly used in calculations in actual affairs. For example, this question is about the production and management of military uniforms in military service and support management. There are many small classifications similarly.

It is typical applied mathematics.

Zhao Huan nodded. He also thought it was not difficult. Since Zhu Lian is a good girl, it shouldn't be difficult.

In his impression, girls are generally poor in mathematics.Since she knows it well, the students of Song Dynasty shouldn't find it difficult.

Zhao Huan overlooked a basic fact, mathematics, regardless of gender, is not at all!

Although it is true that males are generally stronger in mathematical logic, it has a great relationship with the education they receive.

Zhu Lian sat on Zhao Huan and wanted to write down the answer to this question.

Zhao Huan got up and asked Zhu Lian to sit down. He must sit upright when writing calligraphy, otherwise the handwriting would be unsatisfactory.

Zhu Lian's handwriting is extremely beautiful, and the answers in the whole article are logical and self-consistent, and the answers given are also well-founded.

"Not bad." Zhao Huan blew the ink on the paper and put it in the envelope, just follow this answer.

However, he quickly wrote an answer, dried the ink, and was about to put it in an envelope. Zhu Lian asked curiously, "Can you show me what the official wrote?"

"No." Zhao Huan said.

"Oh." Zhu Lian was a little frustrated, it must be some important military affairs, she thought comfortingly.

"Unless you..." Zhao Huan whispered in Zhu Lian's ear, and made a very good suggestion.

Zhu Lian blushed, and said coquettishly: "The officials really never forget this..."

"Then show me. I will accept you." Zhu Lian nodded with a blushing face.

Zhao Huan laughed loudly, and picked Zhu Lian up. Anyway, he couldn't go out in the rainy day, and he didn't have a book, and the beauty was by his side, how could An not move his index finger?
"Officer! It's daytime!" Zhu Lian said, patting in fear.

"What I want is the daytime." Zhao Huan ignored Zhu Lian's feeble slapping.

"Hey..."

The letter passed by Zhao Ding's motorcade, and came into the hands of Li Gang, the chief examiner of Bianjing City.

An excellent prime minister knows when to strengthen the administration of officials. Although the official fined the salary for half a year, Li Gang still read Zhao Huan's idea of ​​changing the court.

Otherwise, why set up schools of administration in Yanjing, Bianjing, Lin'an, and Chengdu?
Teach others how to be an official?

Li Gang didn't think it would be so simple.

He sat in the examination room and received this standard answer letter from Yanjing. When Li Gang saw the handwriting, he knew that it was not an official handwriting, but should be written by Zhu Lian.

The answers are extremely correct and excellent, a question that a concubine in the harem can solve, there is no reason that a student who has studied hard for several years cannot do it.

As long as it is an individual, it cannot escape a psychological effect called the halo effect.

When a person has a certain characteristic, he will make similar judgments about other characteristics.When you see a certain trait in someone, you don't see other traits.

What Li Gang saw was the ability of their poems and songs that they had studied hard for ten years, but he forgot that the students were not like him.

Most of his test papers are such double-set surplus, or mathematical problems called overall planning.

As a result, when grading the papers, Li Gang couldn't help scratching his head when he looked at the answers on the test papers. Was the question he posed difficult?
"Master Liu, take a look at this question. Is it difficult?" Li Gang gave the question to Liu Yi, and Liu Yi held it for a while and said, "It's very simple."

"This is the answer sent back from Yanjing. It should be written by Concubine Zhu. You can take a look." Li Gang handed the answer to Liu Yi. Some hesitation.

"Place the number of people between the left and right, place the name of the given object above it, and place the surplus number below it. The placement of this first step is extremely correct."

"Multiply the dimensions, first multiply the number of people by the rate, subtract the remainder, and then multiply the number of people. The arithmetic skills of cross multiplication in this step are excellent."

"In the future, if you multiply the surplus by the surplus, you will win. There is nothing wrong with this step."

"The upper and the lower are combined, and the upper and lower are combined to form the real thing. The lower and the multiplied are sent to form the military. Both are in accordance with the law. But one can get fifteen thousand and 120 soldiers. Then the other three things can be solved. Output: 30 bolts of cloth, 4 grains of cotton, and 330 six catties of wadding."

"it is good!"

"The five-step method is very clear, the steps are complete, and the order is clear. Concubine Zhu Gui is also a capable person. Didn't the officials give the result?" Liu Yi asked after reading the answer.

Li Gang took out a piece of paper and said with a smile: "This is written by the official. I used a lot of questions from Fangwai. I was a little dizzy when I read it. There are also merits, for students who memorize by rote and do not seek to understand, this method may be better."

"But we are selecting officials, how can it be possible without asking for a deep understanding?"

"Oh?" Liu Yi took the answer given by Zhao Huan.

In fact, Liu Yi has seen Fangwai characters. After all, there are Leye people in the city, and Liu Yi has seen their characters before, but he knows that each of these Fangwai characters has no meaning.

But it can represent everything, just because it is easy to write.

"Li Dazai, you have greatly misunderstood the official. The official did not simply push a formula, but more of a...a kind of...induction and summary thinking! That's right!" Liu Yi looked at the official. According to the various assumptions given by experts, the derived formula says!
"Oh? Is there really a deep meaning?" Li Gang took it over and looked at it carefully, but he still didn't see any major connotations.

Liu Yi laughed loudly, and said, "Fang Wai is not useless. I will keep this answer for now. I always feel that the officials are repeatedly reminding me of some inspiration, but I can't understand the holy meaning."

"You people are all cultivators and seekers of the Tao. Who knows what you are talking about." Li Gang continued to mark the papers according to Zhu Lian's answer.

It is a method and method of education fairness repeatedly emphasized by officials.

Zhao Huan waited refreshedly for the results of the national examination in Bianjing, but first he waited for the hundred students and Zhao Ding who came by the fast train.

They brought coir raincoats and came to Yanjing City in the torrential rain.
