Chapter 324: Preaching Arithmetic
"How dare you! Master Deng is a human being, I know it very well! Lin Su smiled: "Where is Brother Deng currently in high school?" β
"The students don't dare to be so respectful to Master Lao, the students are currently studying in the White Deer Academy to prepare for the palace examination in two years."
"Bailu Academy, the top university in Dacang, if you are not a junjie, you can't enter, Brother Deng can enter here, and he is also a generation of junjie. Initial update @ "
He is still called a brother......
Deng Qiushan sighed: "Lord Lin, the student also heard what the adults and his father said, do you really think it's possible?" β
"You think it's impossible?"
"Bailu Academy has an arithmetic department, including the world's arithmetic masters, and studies the "Nine Chapters of Arithmetic" every day, but to this day, I have never heard of a calculation method that can improve the efficiency of ten times, if there is really one, yesterday's students asked for it, it should be another way of saying."
He made a special trip to Bailu Academy yesterday to ask for help from the arithmetic department of the college.
However, it was denied!
Even if he was a student of the Upper House of Bailu Academy and regarded the academy as his home, he was still rejected.
The suppression of the court officials is one thing, but more importantly, the academy arithmetic department cannot solve this problem at all, if it can be solved, even if the wind direction is not right, after all, some students are willing to stand up, after all, to solve such a problem, it is a great opportunity to become famous in the world, and no one wants to miss it.
"There are "Nine Chapters" in the way of arithmetic, but there are not only "Nine Chapters", things are man-made, and there are always some new methods that can be created...... By the way, do you have a carpenter in your house? β
"Yes! Do adults have to do something? β
"I'll draw a sketch, and you ask him to make it for me quickly......" Lin Su picked up the pen and paper on the bookshelf and drew a very simple sketch, what sketch? Abacus!
Deng Qiushan picked it up and looked at it, but he didn't know why.
Lin Su simply said the precautions for converting this sketch into a real thing, and asked him to do it.
Deng Qiushan went out, found the carpenter in the house, and immediately started work.
In less than half an hour, an abacus appeared in Lin Su's hand.
Deng Qiushan waited with great interest for Lin Su's demonstration, and at this time, the person from the household department had already arrived.
Most of the people who came were young people, looking at the clothes they were wearing, most of them were of no grade, and the housekeeper was embarrassed to introduce that these people were all from the Accounting Department of the Ministry of Households, and the list issued by the adults was forty-six people, but there were twenty-seven people, and the rest of the people, some were not in the department, and some had other important things to do......
A voice came: "Didn't Zhou Su, Zhang Jun, and Li Yangfei come?" β
Lin Su looked up and saw Deng Hongbo, the old man Deng was standing on the steps with his clothes on, his face was quite unright.
Twenty-seven people knelt down at the same time, see Lord Deng......
The housekeeper bowed down and replied: "Master, these three old slaves know that they are the pillars of the Accounting Department, and this matter is indispensable to them, as soon as the old slave enters the Accounting Department, they are looking for them, but these three people refused, they said that they had received instructions from Lord Li to calculate the funds of the Ministry of War." β
Deng Hongbo was furious, his beard flew up, the accounting funds of the Ministry of War had already been completed, and it was the last little bit of the remaining account, which could be used with these three elite soldiers? When he fell ill, these three people were very idle in the division, and when he was about to do it, all three of them had something to do, and the Lord Li in their mouths was the right attendant who followed Lord Shangshu closely and carried the gong opposite to him......
Lin Su hurriedly spoke: "It's nothing! Enough of these people! β
That's enough?
Deng Hongbo's eyes widened suddenly......
"Come, let them all come to the study!"
Lin Su turned around and entered Deng Qiushan's study, and the twenty-seven people also bowed their heads and came in, feeling uneasy in their hearts.
They know Lord Deng's task, and they also know that this matter is impossible to complete, they are suddenly involved, there can't be anything good, and it will make them bear the pot of "can't complete the task".
Lin Su spoke: "Do you understand, what is the purpose of asking you to come here today?" β
Some of the twenty-seven nodded, some shook their heads......
Lin Su clarified the task: "What you have to do is to gather the strength of 27 people and spend half a month to complete the account review of the household department last year." β
"Your Excellency...... This can't be done! A young man looked up.
"yes, big. (This chapter is not finished!) )
Chapter 324: Preaching Arithmetic
People, it's not that the villains are not unsatisfied, even if the villains are tired to death in the reckoning room, it is impossible to complete this matter, the villains are tired to death, and even the adults are blamed by His Majesty. β
All of a sudden, the study was bustling......
If you dare to say it, you can't say it, you can say it and you can't say it, all of them have been said.
The abacus in Lin Su's hand rang out, and all the sounds were muted......
Lin Su said: "Some things seem impossible, but they are actually possible, how about we do a test on the spot?" β
A young man at the front said, "How do you test it?" β
"Give me a number for each of you, no matter how big or small, and I will add it up to you. After you report and I finish calculating, do you think it is possible? β
Everyone was stunned!
Is this possible?
How can it be?
The young man blinked: "My lord, you said that no matter how big or small, tens of thousands of dollars are fine?" β
"Yes!"
"How long is the interval between the two groups?"
"When your voice falls, the second person can report the number!"
Deng Qiushan, who was at the door of the study, shook his whole body, Huo Ran raised his head and looked at Lin Su in disbelief.
Lin Su beckoned to him: "Come, Brother Deng will write down the number they reported next to him, so that when it is over, he will check whether my calculation is accurate." β
"Good!"
Outside the study, a little beauty hid under the window, quietly watching, suddenly, there was one more person in front of her, it was her father, the little beauty flicked suddenly, about to run away, her father stretched out his hand, pressed on her shoulder, not allowed to move, so, secretly watched another person......
Twenty-seven people stood straight, Deng Qiushan stood beside the table with a brush in his hand, and Lin Su's hand pressed on the abacus: "Let's start!" βjj.br>
The young man at the front was the first to report: 37,521 23 cents and 4 cents......
Lin Su's fingers moved, and the snapping beads sounded, and after he finished reporting, the beads were silent......
The audience was quiet......
"Keep reporting!" Lin Su Dao.
The number of second people reported: 42,632 24 cents......
"Go on!"
Third person reporting ......
"Don't wait for me to remind you, after the person in front finishes reporting, the person in the back will consciously pick it up!"
The people in the back were stunned......
Pick up!
Again!
Also pick up ......
Deng Hongbo's face outside the window changed, what kind of song is this playing? On-site calculations? Where's your calculation? The Accounting Division is the most efficient place in arithmetic, their arithmetic chips are ten times higher than others, and their arithmetic chips are divided into ten, hundred, thousand, and ten thousand, what does it mean? The thousand-word number is counted as a thousand, and when it encounters a thousand, it is counted with a thousand-word chip, so their accounting is much faster than the outside world's calculations.
But no matter how fast it is, it can't be that fast......
10, 15, 20......
Deng Qiushan has written a full page of the title......
Twenty-five, twenty-six, twenty-seven......
"It's all over!" The last person finished the number and added four words.
Lin Su glanced at the numbers on the abacus and read, "One hundred and twenty-four thousand six hundred and twenty-seven taels and eight cents." β
The whole process took half an hour.
Everyone looked at each other, and this is the end?
The number of 27 groups, the number of each group is an astonishing number of 10,000 digits, and all of them are whole and round, and they are read out at such a fast pace, Deng Qiushan never stopped writing a topic, and he pulled a few times on this strange bead, and the calculation was finished? Why is it so untrustworthy?
It must be scribbled!
Lin Su read their eyes: "You guys review it, after verifying my results, let's move on to the next step." Shi Shiran walked out of the study.
In the study, twenty-seven people took out the fastest speed and began to review, it took an hour, the strength of twenty-seven people, the result came out, and the moment the result came out, everyone was dumbfounded.
The answer given by Lin Su is completely correct, not bad at all!
There was a loud shout in the study, followed by everyone blowing up......
Lin Su appeared at the door of the study again, and what he came into contact with was a group of fanatical eyes. _o_m (This chapter is not finished!) )
Chapter 324: Preaching Arithmetic
God is the eyes of a fairy. Lin Su was also a little proud in his heart, he had never used abacus at all in that world, but he knew the rules, with the blessing of Wenxin, as long as he knew the rules, he would become a master of abacus in a blink of an eye.
Lin Su said: "Twenty-seven groups of seven-digit numbers, half an hour to complete the accumulation, the people of the world think it is impossible, but I can!" Is this what I can do? Not! It's just that this new algorithm has subverted your perception. β
Modern Algorithms!
Twenty-seven people, plus Deng Qiushan, Deng Hongbo outside the window, and Teresa Teng's hearts were beating, and they had already witnessed the magic of this algorithm.
Can you please ask him for help? If he is willing to make a move, he will have half a month to approve the annual accounts...... It's really possible!
"Want to learn?"
Lin Su's three words came out, and the whole house was quiet. Error-free updates @
What do you mean? Why are you so quiet? You don't cheer this handsome guy and it's very unfulfilling......
After a long time, the young man cautiously asked, "Sir, what do you mean...... Can you teach us such a skill? β
"Naturally!"
Twenty-seven people looked at each other, all of them surprised, delighted, and a little incredulous......
"It seems that the people in the officialdom are very reserved!" Lin Su said: "Okay, whether you express your position or not, I also know that you want to learn, and now start teaching...... This set of algorithms, called abacus, needs the help of a tool, I named it abacus, the abacus seems simple, in fact, it contains the university question of the operation, a bead above this, with a generation of five, the lower bead, one is one, two is two, three is three, four is four ......"
He explained the basic framework of the abacus.
Everyone's eyes are as bright as stars, like smelling the avenue.
"After understanding the most basic framework, it is the operation rules, and the operation rules have an addition formula, which everyone is familiar with and memorize...... One up, two on two, three down five divided by two, four to six into one, five to five into one, six on one to five into one, six on one to five into one......"
He recited the mantra in his mouth, and the abacus beads in his hand flew over to make a demonstration......
In the study, the shadow of the sun shifted westward......
Under Lin Su's feet, I don't know when a circle of lotus flowers was generated, a strange fragrance permeated, and there was also a faint holy light all over his body, and the voice in his mouth was spit out, and the golden lotus blossoms were faintly generated in the void......
Elephant of the Preaching!
The Great Dao Golden Lotus, which can only be found by the top Confucian preaching, was generated from under his feet, and the mouth of the sage's preaching golden lotus loomed in the air, and these were not half alert to the people present.
They were brought into the preaching, and there was only the Great Dao and no everything, and the comprehension of the people was also raised to an unbelievable level, and the understanding of the abacus changed from vague to clear, and gradually became clear, and everyone had a kind of ecstasy when they first heard the Great Dao......
An hour later, Lin Su finished talking about the abacus.
Everyone woke up from a dream and bowed at the same time......
"Mr.'s wonderful skills, it's really like a celestial, I don't know if Mr. is a top Confucian in the White Deer Academy?" The young man was pleasantly surprised.
The rest of the crowd also stared at him with burning eyes, and asked the same question.
They don't know Lin Su, but who in the world can have such a magical skill? There is no doubt that only the top Confucian of the White Deer Academy is the arithmetic department, and the arithmetic department of the White Deer Academy is the ceiling of arithmetic in the whole world.
Lin Su said: "This question is not important, what matters is ...... It is not enough for you to rely on abacus alone to ensure that nothing goes wrong, I have another method, which can be used to achieve twice the result with half the effort! This skill is called ...... The big number of symbols, simplifying the complex......"
As soon as his hand stretched out, a piece of paper flew out of thin air, and the pen in Lin Su's hand fell, and 1, 2, 3, and 4 were written on it......
This is one, this is two, this is three......
This is the decimal point, if it is in "two", the first digit after the decimal point is "money", and the second digit after the decimal point is "cent......
In this way, the complicated long string of words becomes a number, which is more intuitive and easy to calculate......
Another hour of preaching, the image of preaching reappears!
The piece of paper in Deng Qiushan's hand was also marked by him as Arabic numerals, and with such a mark, his heartbeat accelerated, and it really became simple, convenient and intuitive......
γ (This chapter is not finished!) )
Chapter 324: Preaching Arithmetic
It's not over yet, the heaviest skill is here......
Lin Su got up and drew a grid chart on the paper......
"You are all from the Accounting Department of Dacang, but please forgive me, your accounting methods are extremely primitive, extremely backward, and the collection and payment are not distinguished, and the calculation is not clear, so I pass on to you a new accounting rule, which I name: the collection and payment accounting method ......."
The new numeric symbols are included in the table, with the front being the receipt, the back being the branch, and the balance obtained by netting......
Clear, simple and convenient......
This time, the vision of the preaching was particularly strong, and the golden lotus cheered and jumped, and it seemed that they also felt the great changes of the times......
After all the teachings were completed, Lin Su walked out of the study, and the golden lotus under his feet shook, rose to the sky, and disappeared out of the sky.
The door of the study was pushed open suddenly, and Deng Hongbo appeared at the door of the study: "What do you think?" He eavesdropped outside the window for three hours, but he was not an arithmetic talent after all, and he did not know the way of arithmetic, so he did not understand it very well.
"My lord, this is the skill of heaven and man!" The young man's face was flushed with excitement: "Xiaguan dares to guarantee that even if there are only ten people, the review can be completed within half a month!" β
"Really?" Deng Hongbo grabbed his shoulder violently, and his face suddenly turned red like blood.
"Xiaguan promises that it can!"
Another person stepped forward: "Absolutely! β
"That'...... What are you waiting for? All back to the Accounting Division, start work overnight! Deng Hongbo threw off the clothes on his body and rushed out of the study, at this moment, how could he be half sick?
The young man rushed out a few steps and turned back sharply: "Deng Gongzi, that gentleman...... You were invited from White Deer Academy yesterday, right? Who is he? β
He ...... It's Lin Su, the champion Lang Lin Su! β
What?
Everyone present was stunned!
It's not the top Confucian of the White Deer Academy department at all!
He is the person who stirs in the literary world and keeps the Beijing bigwigs secretive!
He is famous all over the world for his poetry, how can he be a peerless genius who pioneered arithmetic?
Deng Hongbo urged, and they went to ....... @η²Ύε\/Shuge*First update~~
