The pension plan of the ancient cannon fodder woman

After class, Su He left the academy directly.

I'm so tired, so tired, I'm going home to lie down.

Su He could only comfort himself that he could take a rest in the archives room tomorrow.

The next day, Su He happily came to the archive room with a bunch of snacks and a pot of milk tea. He put everything on the table first, and then lay down.

Su He prepared to take a nap and then get up and enjoy the meal slowly.

Huh? Why do I see someone looking at me?

Su He was startled when she opened her eyes. A group of people were looking at her.

"You are?"

"Master, you don't remember me. I am Zhu Linghui."

"Master, I'm Liu Yanzhen, let's ask some questions."

Su He quickly sat up, "Come and have some snacks, I remember you guys, why are you here to ask questions so early? Don't you have classes?"

"We said we needed to use the toilet and came running."

The two of them were eating the preserved fruits given by Su He with a smile on their faces. After asking two random questions, they started chatting with Su He, and were then urged by the second-grade students behind them.

"Master, it's our turn."

Zhu Linghui and the other person could only walk away with pouting lips.

I made an appointment with Su He before leaving.

"Master, we will have lunch with you later. Don't run around in the archives room."

Su He didn't know whether to laugh or cry, but looking at the sincere eyes of the two children, she couldn't refuse.

"Okay, I'll wait for you here."

There were more second-grade students, but the questions they asked were not difficult. Su He explained quickly and gave three ways to answer the questions.

When Su He felt his mouth was dry and wanted to drink a glass of water to moisten his throat, he suddenly found that there was a long queue behind him.

"What are they?"

The student who had just asked the question replied, "Master, they are all here to ask you questions. I see there are more than thirty of them."

Su He only felt darkness in front of his eyes, it was horrible.

This is worse than attending class.

"Master, I took the form you gave me back yesterday and it has already marked more than 300 numbers. This one is too long. I feel dizzy just writing the numbers."

The third graders took the forms home yesterday to use, and they found many problems when they did.

"The numbering doesn't have to be all numbers. We can do this. For example, for fabrics, silk and satin, you can further subdivide them, such as ling, scattered flower ling, and heavy lotus ling. You can number them as scattered and heavy. You write it like this. First write a small word "ling" in this space, and then the number below is the name plus the number. For example, if you have six pieces of scattered flower ling, you can write "scattered six", and ten pieces of heavy lotus ling would be "heavy ten."

The third grade girls all gathered around and watched Su He take out a strange black pen and write.

"Master, fabrics can be numbered like this, but what about wood? I have a lot of Huanghuali wood, stools, chairs, beds, and large and small ornaments. How should I number them?"

Su He smiled, "This is also very simple. We can solve it using arithmetic thinking."

"There are many methods. I will talk about the first one first. First, you have to base it on..."

The girls held their breath and watched Su He demonstrate three different methods on the table.

"That's basically it, do you girls understand?"

Su He looked at the third graders with a smile, and Wan Ning mustered up the courage to speak.

"Master, my dowry is too large, and my maids are illiterate, so they are too slow to sort it out. Can I ask you to come to my house and help me sort out my dowry? I will give you five thousand taels."

"what?"

Su He's brain froze for two seconds, then he sorted out the amount, five thousand taels.

"Well, the teacher still has to go to class, so he may not be able to go."

Although Su He was somewhat tempted, she didn't want to touch other people's money, as it was not easy to earn money. She also didn't want to stay in someone else's house.

"Master, my grandfather was an examiner for the provincial examination for three years. He has some experience in the undergraduate examination. I have been planning to take him as a dowry, but I don't need him. I am marrying a useless second son. Give him to your younger brother. He will definitely need him."

This doesn't have to be so straightforward.

Su He didn't know whether to laugh or cry. Before she could refuse, the girls around her all stopped working.

"My dowry is also large, Wan Ning. I got married earlier than you. Please let me go first. Master, I have many books at home. You can pick any of them. It's okay to pick a hundred. Please come to my house first."

"Lin Qiu, where do you get so many books? Don't you like riding horses and archery?"

Ye Linqiu was furious and said, "Is it not okay for me to take the books from my father's study as my dowry?"

"Master, don't listen to her. The books in her house are just for show. I guarantee she hasn't even turned a page. They can be sold as new books. Master, the books in my house are different. My two brothers have become officials. The books they left behind have notes. Your brother will definitely need them for the provincial examination. If you choose me, come to my house first."

"No, you're not getting married until next year, so you're not allowed to jump the queue."

The girls, who had been living in harmony, suddenly began to confront each other.

Su He had a headache. She never said she would help to prepare the dowry. These girls looked young and were all very cunning. They even knew that she had a younger brother who was preparing to take the imperial examination.

Wan Ning took the opportunity to come over and said, "Master, I have an uncle who teaches at Yunkai Academy. The library of Yunkai Academy has handwritten versions of the examination papers of the top scorers in the imperial examinations over the years. Only the masters of Yunkai Academy can go in and read them."

Su He stared at Wan Ning with eyes wide open.

"Master, your brother's name is Su Che, right? I'll ask my uncle to vouch for him, and he can go in and see it."

Su He looked at Wan Ning with sparkling eyes and nodded with a smile.

"Okay, let's wait until the day after tomorrow. The day after tomorrow is a holiday, and the teacher will go to your house."

Wan Ning smiled happily.

"No, Master, I heard everything. I want to go too. Master, you should pack up Wan Ning and come to my house. I have a lot of delicious food at home. You will not be disappointed when you come to my house."

The scene became even more chaotic, and the final result was that all the students in the third grade went to Wan Ning's house to watch the teacher count the dowry.

After finally seeing off the third grade girls, Su He had no time to drink a sip of water before people from the preparatory class came rushing over.

"Master, we have a question here, and we don't have any ideas. I want to ask you."

Su He laughed after watching it for two seconds. It's like chickens and rabbits in the same cage.

"There are many ways to solve this problem. The first one is called the hypothesis method. Let's assume that they are all chickens. Then twice the total number of heads is the total number of legs. Now who can tell me what twice the total number of heads is?"

No one expected Su He to ask a question on the spot, so there was silence for a long time, and some people even subconsciously picked up the abacus.

Su He didn't wait any longer and gave the answer directly, "It's 75."

"Everyone, look at the question carefully. How many legs does it say?"

"Fifty."

This time everyone answered quickly, after all, the question was in it.

"Yes, what does this mean?"

"It means there are rabbits. The above assumption is wrong."

Xu Qiao thought for a while and gave an answer.

"Yes, that means there are rabbits besides chickens. Rabbits have two more legs than chickens. Let's think about it the other way around. Doesn't every missing two legs mean there is a rabbit?"

Seeing that everyone looked confused, Su He started drawing rabbits and chickens on paper.

"Let's start with something simple. Look, this is a cage of chickens and rabbits. The total number is..."

........

"So we can derive two rules. The first one is, assuming that they are all chickens, then the number of rabbits is: twice the total number of heads minus the total number of legs, half the result. The second one is, assuming..."

"Put in all the numbers in the question and try to do the math."

A quarter of an hour later, "Master, there are 23 chickens and 12 rabbits, right?"

Xu Qiao was the first to answer.

Su He smiled and nodded, "Yes, the questions can be varied. As long as you are good at summarizing the rules, no matter how the questions change, they will be visible in your eyes."

"Master, is there any other way to solve the problem?"

Someone asked curiously.

"Yes, there are many. You can think about them."

Xu Qiao looked at Su He and asked, "Master, how many more can you make?"

"Four kinds."

Now even Xu Qiao was silent. She had specifically asked her father for this question, the eternal problem of Yunkai Academy.

Yunkai Academy has only come up with one answer so far. Xu Qiao thought of the thick answer book her father had given. For the first time, she began to question her father's IQ.
