farmer's struggle

Butler Chen was taken aback for a moment, then came to his senses, and his thoughts changed. Seeing that Li Yu was about to go far away, he hurriedly called Li Yu, "Mr. Li, please stay!"

Hearing this, Li Yu thought that Steward Chen had something else to say, so he stopped and turned around, "I don't know if Steward Chen has anything else to say?"

Steward Chen hurriedly took a few steps forward and asked, "I haven't seen Li Langjun use calculations on the eggs just now. How did he get the result all at once? I ask Li Langjun to enlighten me."

He obviously saw that Li Yu didn't use calculations, but he was able to calculate the correct answer in such a short period of time. come up with the correct answer.

Li Yu has black lines all over his head, isn't this the most basic algorithm?Why do you still have to ask him?It can be seen that Steward Chen's expression does not seem to be joking with him.

Li Yu hesitated, "Here, there are two eggs, 46 eggs, and you can know the answer if you do the math in your mind. Multiplying two numbers is like a duck egg. What is the calculation chip? Is it an abacus?"

Butler Chen was stunned. Doesn't Li Yu even know how to count?What do you mean you can know the answer by doing a calculation in your heart? How do you calculate it?What is multiplication?And what is the abacus he mentioned?

The two stared blankly for a while, not understanding what the other meant. Finally, Steward Chen invited Li Yu into the mansion after buying the eggs.

Li Yu couldn't refuse, so he had to agree.

Steward Chen served him some tea, then sat down and asked, "Li Langjun seems to have a unique understanding of algorithms. I wonder if he can explain the confusion to the villain. What is the multiplication that Li Langjun is talking about? Abacus is calculation." ?”

Li Yu took a sip of tea, his heart racing, how could he not know how to multiply?How do people in this era count?

"The abacus is a calculation tool. It is a rectangular wooden frame with strings of equal numbers of beads arranged in it. There is a beam in the middle that divides the beads into two parts. It can be calculated within a few days, is this the kind of calculation you are talking about?" Li Yu thought for a while, and directly described the abacus of later generations.

Steward Chen frowned when he heard the words, shook his head and said, "It's not like this, I've never heard of what you said." He found a box from the cabinet and opened it, "This is the counting chip, we all use it to count, count."

Li Yu looked intently, and saw that there were long and short wooden sticks in the wooden box. He was dumbfounded, "How do you count this?"

Seeing Li Yu's bewildered expression, Steward Chen vacated the table at hand and said, "I'll show you the algorithm of the egg just now." As he spoke, he took out the wooden sticks and placed them on the table in an orderly manner. On the table.

After a while, half a table was set up, and finally he stopped and said, "It is indeed 120 Wuwen."

Li Yu supported his forehead and stammered, "You, do you think so? Don't you think it's troublesome?"

"It's all calculated in this way. I wonder if Li Langjun can teach you your algorithm?" Steward Chen said modestly.

"Eh..." Li Yu thought about it, "Do you have a pen and paper?"

Steward Chen immediately ordered someone to fetch some paper and pens and hand them to Li Yu.

Li Yu took the brush with a bitter face. He doesn't know how to write with a brush, but under the eager gaze of Steward Chen, he still bite the bullet and wrote, explaining while writing: "When two numbers are multiplied, there is ninety-nine." For the multiplication table, beginners can easily figure it out by writing out a formula. People who are familiar with it can calculate it directly in their hearts without paper and pen. I just calculated it in my head outside."

Steward Chen stared at the earthworm-like lines on the paper very seriously. What kind of scripture is this? He can't understand a single word?

After finishing writing, Li Yu looked at Butler Chen's covered face, scratched his head and smiled embarrassedly, "Hehe, I don't know how to write calligraphy very well, and the handwriting is a bit ugly."

It's not that ugly, a three-year-old child can write straighter than him.

Butler Chen didn't understand it, but Li Yu explained it anyway. He had a little understanding, knowing that Li Yu's method was much simpler and more straightforward, and he also felt a little thoughtful.

"I have a problem here. I would like to ask Li Lang-jun for your advice." Steward Chen cupped his hands and said, "I have one mu of fertile land at a price of three hundred, and seven mu of Susukino land at a price of five hundred. Now I can also buy one hectare at a price of ten thousand. , Susukita how much to buy? Note 1"

Li Yu snorted, this question is beyond the outline, and he has been promoted from elementary school to junior high school all at once.

He picked up the pen with a smile, dipped some ink, and began to write and draw on the paper. After a while, he stopped writing and said: "I bought 12.5 mu of good land and 87.5 mu of Susukida."

Steward Chen was in shock, and ran out the door without saying hello.

this?Does this scare people away?Li Yu was at a loss and couldn't figure it out.

After a while, Steward Chen ran back out of breath, his face flushed, and his attitude became more respectful, "Mr. Chen is amazing! I figured it out so soon. I still have a question here, and I hope to answer it." After speaking, he handed over a piece of paper note.

Li Yu took a look and saw that there were neat and beautiful handwriting on it, which didn't look like it was written by Steward Chen. 'Today there is one rooster worth five coins; one hen mother worth three coins; three chicks worth one coin.Every hundred dollars buys a hundred chickens.How about the rooster's mother and chicks? ' Note 2

Li Yu frowned. At this time, he also saw the meaning of their comparison, and immediately felt a little unwilling to admit defeat, and began to write on the paper.

In less than a quarter of an hour, Li Yu wrote down several correct answers to this question and handed them to Steward Chen.

Butler Chen took a look, didn't understand, and hurried out again.

This time I waited for a long time before I saw Steward Chen turn back, and Li Yu didn't want to delay any longer, so he was about to leave and go back, but he heard Steward Chen say: "Li Langjun, I have a heartfelt request here, I hope Li Langjun will do the same." Listen."

Li Yu swallowed the words again, and nodded.

"Li Langjun, you know that my master has been working as an official outside, and now he has just returned from his old age and returned to his hometown not long ago, so the family has never had enough staff." Chen Butler said, seeing that Li Yu was listening carefully, he continued: "Now the property store at home Everything is going to waste, and it is the accountant who needs to sort out the accounts. However, after so long, I have not been able to find a suitable person. When I met Li Langjun today, I really did not expect that Li Langjun has such amazing skills in mathematics. Talent, our Chen family wants to hire Li Langjun as the accountant, I wonder if Li Langjun is willing?"

"This!" Li Yu never expected Steward Chen to make such a request. In the past, he encountered obstacles everywhere when looking for a job, but now the job came to him automatically.However, he is busy with making sugar and cakes now, so I'm afraid he doesn't have time.

Li Yu thought of this, tapped the table with his fingers, and said very euphemistically: "Chen Steward, you know that I have signed a contract with Xu Fangzhai to supply pastries, and I have to be busy with this matter every day, and I really don't have time to be the accountant. .”

Housekeeper Chen naturally knew about it, and he really had no choice but to go to the doctor in a hurry. Without an accountant, the business of the Chen family couldn't get on the right track.

He showed the eldest son the problem just now, Li Yu actually solved the problem that even the eldest son could not solve, which is enough to prove Li Yu's ability.

Seeing Li Yu's tactful refusal, Steward Chen was a little anxious, not knowing what to do, when he saw a man in white clothes coming in outside, it was Chen Zizhuo, the eldest son of the Chen family.

"Li Langjun, don't rush to refuse, you can listen to the conditions first." Chen Zizhuo said in a clear voice.

Li Yu touched the bridge of his nose and was about to speak, but he heard him say again: "I can give you three monthly money, you just need to check the account book and clean up the accounts. I think you are proficient in arithmetic. It’s fast and accurate, such small things shouldn’t bother you, and if it’s you, you don’t need to spend too much time on the accounts, and you can take care of your family’s affairs.”

Sanguan means three thousand wen, which is equal to three taels of silver. He can earn so much salary in a month. After earning three taels of silver, his eyes began to shine, and he was quite moved.

Li Yu thought for a while, "The working hours? Oh, no, is there any requirement for working hours every day?"

Chen Ziyan put his arms around his chest, as if he was sure that Li Yu would definitely agree, "At the end of each month, arrange five days for reconciliation and settlement, and you can arrange the rest freely. I don't know if there are five days, your account book can be done without any mistakes. ?"

Li Yu did the math, he could earn three taels of silver by working five days a month. What is the difference between this and picking up money for free?Only a fool would let such a good opportunity go.Immediately nodded and said confidently: "No problem, as long as there is a mistake, you can deduct my salary." This is considered to be his agreement.

"Very good, when the time comes, I will prepare an employment contract, and I can start working after signing it." Chen Zizhuo said very satisfied.

"Well... I, I have a request, I don't know if I should say it." Li Yu rubbed his hands and said embarrassedly.

Chen Zizhuo raised his eyebrows, "Just talk and listen."

"Hey!" Li Yu said with a shy smile, "This boss, can you let me pay half a year's wages in advance, if not, I can pay in advance for three months." No way, money is tight, he still needs a big house It’s better to repair it earlier, the weather will get colder as you go, and people will suffer a lot if you live in a house with air leakage on all sides, so it’s better to repair it earlier, so that you can move in directly when the weather gradually cools down.

"Advance payment?" Chen Zizhuo and Chen Butler looked at each other, this advance payment of wages was unheard of, "How to advance payment?"

"Just settle half a year's wages with me in advance, and then I won't have to pay wages for half a year. How about doing it after half a year? I'm also short of money. If not, I wouldn't agree to be the accountant. " Li Yu replied honestly.

Now they understand, Chen Butler is a little worried, this is not listed first, "Master, look at this—"

Chen Zizhuo pondered for a while, then nodded resolutely and said to Steward Chen, "Steward Chen, take him to advance some money first, and put my flowers on top first." After speaking, he said to Li Yu: "I can advance your money first. , but I also have a request, that is, you have to teach the second young master your arithmetic method."

"It's okay." Li Yu patted his chest happily to reassure him. Knowing that the matter was done, he saluted and left with Steward Chen.
