When Song Jiu returned home drunk, it was almost three o'clock. He didn't say anything, more than a dozen people poured him wine, the actual amount of Song Jiu's wine was okay, but a good man was hard to beat four hands, and there were more than a dozen people. After a while, he put it down, not really down, but pretending to be down, Song Jiu looked bad at it, pretended to be drunk and vomited, and more than a dozen people laughed and let him go. But it represents recognition of him, and this recognition is rewarded by Zhao Kuangyin.

Sent the eunuch to invite Song Jiu to eat tea and chat, and talked about the freshman conversation, Zhao Kuangyi deliberately turned Song De's deeds out, the emperor and the imperial brother are not the same thing, because they are the close guards of the former Zhou Chai Rong, no one dares to say it. The emperor and the emperor's younger brother agree that their parents are not only Zhao Kuangyin's subordinates, but also Chai Rong's subordinates, so they also agree with Song Jiu. It's your own people, you can't be regarded as a grass people.

Song Jiu didn't dare to say the gambling contract, only said that the emperor agreed to let him make a pilot project on a few acres of Hezhou, and hand over a certain amount of money and silk a year to let him operate. More than a dozen people couldn't hear clearly, and although they were curious, they didn't take it seriously for the time being. However, what "dismounted" had to be, after pouring Song Jiu, he began to pour Xiao Cao Can, and Cao Can, who was only fourteen years old, poured it down in one, two, three. Pan Weide sent someone to send Cao Can back, and Song Jiu didn't know if Cao Bin would smoke Cao Can's ass, so he came again. Seeing Song Jiu coming out, he continued to pour. Not lying down does not count. But an unhappy scene happened during the banquet, Zhang Qiong's son was also not very old, and Cao Can was overwhelmed, everyone wanted to fill Zhang Qiong's son Zhang Lin, I don't know what Lu Dao was for, Zhang Lin and Fu Zhaoshou were about to fight, and they were almost red-faced.

At that time, Song Jiu was almost drunk, and he persuaded a few words from it, and this trouble broke up unhappily, and Song Jiu returned home in a daze.

The door of the house is still open, Zhu San is sitting in the living room waiting for him, there are other people, ten students, Liu Gonggong, there are still a lot of cloths in the corner of the hall, the Song Dynasty has been short of copper coins from beginning to end, and has to use cloth instead of money, or barter in some remote areas.

The copper coins were very cumbersome, and at this time the Song Dynasty itself began to mint money, the amount was not much, sometimes tens of thousands of pieces a year, sometimes only a few thousand, and most of the copper coins of the previous dynasty were used, and even if the copper coins of the Sui Dynasty were well kept, they would still circulate now. On average, the money weighs seven pounds. That is to say, if a big man carries fifteen copper coins, he will be tired and lie down if he can't walk ten miles. But the cloth is more troublesome, a horse of silk is worth more than a penny, a horse of silk is ten zhang, ten horses of silk are a hundred zhang, and that one is heavier and more cumbersome.

The results of the competition came out, a little late, there were a few account books with a lot, until it was dark, and there were some disputes in the middle, the students said I was right, and the account office said I was right, so I re-verified and recalculated. This dragged on to nearly two watches.

Fortunately, Zhao Kuangyin had the foresight and sent guards to watch, otherwise those bookkeepers might have let the guys in the store beat these students in anger and shame.

The main reason is that some time ago, people had cleared the accounts, and the students were not familiar with the single-entry account books, and some words were not recognized, so they fell behind.

Gonggong Liu reported the results to the palace.

Pan's house is not far from the palace, so Zhao Kuangyin rewarded the student with ten yuan and ten silks. But let Father-in-law Liu come to Song's house with a few words.

Song Jiu staggered to pour tea for Gonggong Liu, but Gonggong Liu held him up: "Jiulang, let's let the Sprinkle family come." ”

didn't let him come, Zhu San grabbed it and made strong tea for Song Jiu to relieve hangover.

Song Jiu pointed at the ten students with his finger: "What are your results?" ”

As a result, Song Jiu shouted out the two losing students and reprimanded them loudly. Not to mention arithmetic, with chalk, with an abacus, with abacus oral decision, with this article, it is also ten times faster than those bookkeepers. How can you lose?

The two students are about the same age as Song Jiu, but they are knowledgeable, they talk and laugh with the emperor, and they are Xie Zi and their teachers, so they have to admit their mistakes.

Gonggong Liu stopped: "Jiulang, it's very good, hearing the result, the officials in the palace were stunned." ”

Song Jiu was still furious, and punished the two students to play for half an hour in the back before they were allowed to go home. Playing is playing, making trouble, learning is learning, this is a very progressive method of education, but unfortunately no one pays attention. It's just that Gonggong Liu smacked his tongue slightly, and it turned out that Song Jiu's education was also quite strict.

Gonggong Liu took out a small green robe again, a single coat in white silk, white silk pants, a curved collar in a white Luo square heart, and a two-beam crown, that is, Song Jiu's official uniform and official hat, and the clothes inside. He, a small loose official, will not go to the court, and he will not say anything, but he will also attend some big sacrifices and give him crowns and clothes, which is what comes in handy. But it was this official uniform, Zhu San's eyes glowed green, and his face was envious, Shi Nong Industry and Commerce, the official-oriented thinking of this era is too serious.

Song Jiu said: "Thank you, Your Majesty." ”

Liu Gonggong publicly asked Zhu San to make tea for the Song Dynasty, and he had to drink a little tea to make Song Jiu's mind clearer, and after sipping tea for a while, Liu Gonggong said: "Jiulang, Your Majesty said that you won, but it will be very fast in three years, no matter how you do it, don't violate Song Law, otherwise you will be severely punished." ”

Song Jiu said that the three pictures were just a conjecture, and Zhao Kuangyin thought that it was a random guess, and the wrong idea was only one percent doubt, and one percent did not believe it. But there is a slight belief in Song Jiu's bet. Only one percent.

An inconsequential Xiaohezhou can conjure up 100,000 yuan a year, so wouldn't the entire capital be able to conjure up at least 10 million yuan a year, and wouldn't the Great Song Dynasty be able to conjure up 10,000 yuan a year? . Wang Anshi changed the law to collect more than 180 million yuan in a year, and there were pieces, stones, bundles, horses, and two and silk in the middle, but the average was more than 100 million, which was more than seven times the annual income of the highest state in the Tang Dynasty. If the capital is seriously taxed, all the properties of high-ranking officials and nobles will be law-abiding and good citizens, and the capital will be able to collect more than 2,000 yuan a year. This figure, now that the Zhao family brothers are killed, the Zhao family brothers will not believe it.

Zhao Kuangyin was worried that Song Jiu would use this gambling contract to deceive, but he didn't care too much, it was okay to deceive tens of thousands of yuan, but he could deceive millions? The imperial court doesn't have that ability! So I only let Gonggong Liu give a brief warning.

In fact, Zhao Kuangyin did not expect Song Jiu to collect more than 4 million yuan in the next 50 years, which can reach a quarter, and this gamble will be a huge advantage for the imperial court.

Let him toss first, anyway, he is only in his thirties, he can see it, see if he can't do it in the future, how to see himself. But Zhao Kuangyin didn't know what to do, and Song Jiu owed more than 10,000 yuan in debt.

"Gonggong Liu, please rest assured, I will violate Song Law?"

"That's good. Your Majesty also asked the Sprinkler family to bring you an order. ”

"Please command."

"Your Majesty instructed the Sprinkle family to inform you that the answers to the three questions cannot be leaked, and the court will have another role."

"What is it for?"

"South."

Song Jiu drank a cup of strong tea, his mind was slightly sober, and he reacted, the Song Dynasty was very rich in history, especially the Northern Song Dynasty, and several emperors were not evil, Zhao Ji and his son could not be counted. But it is very soft to the outside world, and a rich country that is greedy for life and afraid of death is undoubtedly a super big fat sheep. Then the year is 800,000 a year, tea, silk, silver, the Song Dynasty silver is very valuable, one or two silver two money, silk is a little better, can be transported to the border, the cost is close to two, that is, more than one million a year is gone, buy an for nearly a hundred years.

Now the Southern Tang Dynasty is a miniature version of the Northern Song Dynasty, and it also attaches importance to internal governance, and the people's life is not too hard, at least because of the terrain and weather, the crop yield is high, and it is richer than the people of the Song Dynasty. Not to mention literature, the Northern Song Dynasty was a giant in martial arts and a dwarf in literature at this time. The Song Dynasty attached great importance to the rule of culture, but it was far inferior to this foreign country in the south. This made the monarchs and ministers of the Song Dynasty feel faceless, so they took out their own three questions to make things difficult for the Southern Tang Dynasty.

How to operate is not something that Song Jiu can ask.

Song Jiu thought for a while and said, "No, Gonggong Liu, I heard many people in the capital commenting that I was deliberately making things difficult for others, and it was simply three unsolvable math problems. The January deadline is coming, and I must publish its solution. However, if the court wants to ask questions, I can come up with three more difficult ones. ”

"This is good, the harder the better."

"But I drank a little too much today, and you can pick up the topic tomorrow."

Sending Gonggong Liu away, Song Jiu fell asleep. When he woke up the next day, it was Zhu San who reminded him that Song Jiu remembered this incident. Think about difficult math problems, don't be too easy to come up with. But it's not so easy to come out.,Most of the math problems in the upper grades can't be solved.,At least now it seems that there is no practicality.,Like the complex geometry of functions, people who look at it often don't know what to do.,Can't understand it.,How to convince people?

Just like if Han Yue translated the stone drum text, no one may admit it, you have the final say!

Song Jiu wrote down the first question, the long history of dredging the river, the amount of silt needs 200 vehicles to be towed day and night for 24 days, the government has 250 vehicles, and there is one standing one, and a car can be pulled out every two hours, and the silt can be dragged away in a few days?

Song Jiu was writing, Zhu San was watching from the side, thinking about it, his mind felt a little dizzy.

Song Jiu wrote down the second question, it takes 1,500 catties of paint to paint the big iron ball, and the sixty-four iron balls of the same size are melted into giant balls, how much does it take to paint the giant ball?

Zhu Sanhu asked suspiciously: "Then there is such a big iron ball?" ”

"Prevent someone from casting it and measuring it instead of calculating it."

Zhu San didn't even know the formula of the circular volume, and he was at a loss for this thought.

Song Jiu wrote down the third question, the output of a certain workshop has increased evenly, doubling in ten years, and what is the annual growth rate?

"That's a good calculation."

"Brother Zhu, it's really easy to calculate, you can calculate?"

If it is said that the annual increase is one percent, and the increase will be ten years later, someone can calculate it, but now it is ten root numbers, which seems simple, but it has become a problem.

These three problems are typical application problems, and they will not be used completely, but if they can be solved, they will encounter many similar practical problems. Song Jiu put it down and began to have breakfast with Zhu San, and after breakfast, a student came to school, and the two doctors were still coming.

Song Jiu said: "Brother Zhu, you teach first, and I'll go out for a while." ”

Slowly came to Beiwazi to see Yuping. In the future design of Hezhou, this beautiful Qiao Xingshou is also an important chess piece.

Yuping hadn't gotten up yet, so she waited for a while before she freshened up and dressed up and took Song Jiu in.

Cui'er served the tea, and Yuping said, "Jiulang, those songs I sang yesterday are very beautiful." ”

The tone is a little sour.

Song Jiu pinched his nose and said, "If the Jade Lady likes it, I will make two small orders for you another day." ”

"The blessing from the slave family."

"Jade lady, I don't have that mind, don't think about it, I came to you just to join forces with you to do an important thing."

"Slaves are thin ......"

"Don't talk about the scene, would you like to?"

"What's the matter?"

Song Jiu didn't answer directly, but asked, "Jade Lady, how much silk will you give to you if you ask the bureau once?" ”

The speaker was unintentional, but the listener was intentional, and Yuping's face turned miserable.
