Chapter 861 Problem Solving
Chapter 861 Problem Solving
The sun gradually rose higher, and the originally cool flower hall was now a little warm.
"Where's the question?" Shen Zheng also spread her hands to Zhuang Quan.
She actually wanted to see what the math problems that troubled many teachers in the capital were like.
"Ah?" Zhuang Quan was still in a daze.
"Don't you have to do the questions?" Shen Zheng looked at the sky. "It's time for dinner in half an hour, and I have something else to do in the afternoon. If you don't come up with the questions, then forget it."
At the end, she did not forget to add: "It's not that I don't want to fight, it's that you didn't prepare enough before the battle, which is more shameful than losing without fighting."
"You——!" Zhuang Quan also stood up immediately, "Wait a minute, I'll go back to the room and get it, wait and don't leave!"
Shen Zheng waved at him and drove him out of the flower hall like she was driving away a kitten or a puppy.
Yu Nanshu hugged her arm and apologized coquettishly, "Sister Shen, Zhuang Quanye's brain has always been a bit slow, so don't bother with him. You must not refuse to hire me as a teacher in the Shen Mansion because of him..."
Feng Qianzhi whispered: "Sister Shen, I also want to listen to Nan Shu's lecture..."
Zhuang Sijing nodded in agreement with Yu Nanshu's words: "My brother is like this. Because my aunt often mentions Sister Shen in her letters, he is very jealous and vengeful. He is a dark villain."
"He actually thinks so?" Yu Nanshu gritted her teeth and clenched her fists. "Even if we want to be jealous, it won't be his turn! Sister Shen, are you sure about what will happen later? If not, I will also..."
As she spoke, she made a gesture of wiping her neck.
Shen Zheng didn't know whether to laugh or cry, "I don't know either. I have to look at the questions first."
Yu Nanshu nodded with a serious face: "Okay, then I will act according to the circumstances. Don't worry, I will never let Zhuang Quan jump in front of you."
Upon hearing this, Yu Jiusi quickly shrank to the side, trying to reduce his presence.
He was afraid that Zhuang Quan would also be implicated.
Fortunately, Zhuang Quan was really in a hurry. In less than a moment, he went back and forth between the flower hall and his courtyard under the increasingly dazzling sunlight.
The sunlight from the hall door was slightly blocked. He walked over quickly, wiped the sweat from his forehead, and slapped the rice paper in his hand on the table.
"Phew, you look at this first. I can't do it anymore. I need to rest for a while."
After saying that, he sat back on the stool and drank directly from the pot.
Shen Zheng straightened the rice paper on the table, and Yu Nanshu also came over.
The question above seemed simple, because it was only a short sentence, but after reading it, Yu Nanshu looked at Shen Zheng helplessly, "Sister Shen, this..."
This question is not even covered in the math class in Tongan County...
So Zhuang Quan also...
Yu Nanshu narrowed her eyes.
Can’t keep it!
"Do you have any paper or pen?" Just as Yu Nanshu was thinking about how to start, Shen Zheng's voice came into her ears.
Zhuang Quan hadn't even caught his breath yet, and looked shocked. "Have you finished reading the questions?"
"I've finished reading it." Shen Zheng nodded. "You only took the test questions, but no paper or pen? Do you want me to do mental arithmetic to solve the problem?"
Zhuang Quan also looked at the rice paper on the table, then looked at her, incredulous: "You... have an idea?"
"How is that possible!" Before Shen Zheng could answer, he stood up again, picked up the rice paper, and read: "Now there is a male chicken, worth five coins; a female chicken, worth three coins; three chicks, worth one coin. If you buy a hundred chickens for a hundred coins, how many males, females, and chicks are there?"
"Is there a trap in this question? Are you sure you understand it?" Zhuang Quan was also a little awkward, but he still told her the trap: "Let me tell you, my teacher said that there is more than one answer to this question, and if you miss one, it will be counted as a mistake."
Even the teachers in the Imperial College had to calculate the answers to the test questions, so how could Shen Zheng have an idea after just one look!
"I know what you mean." Shen Zheng said, "This type of problem may have a solution in ancient arithmetic books, but it needs to be enumerated. In other words, if any number in the question is replaced, it becomes a new problem, and it still requires a lot of trial calculations."
Zhuang Quan also heard this and looked serious.
He asked, "Have you...heard of this kind of question?"
Shen Zheng did not comment.
Yu Nanshu found paper and pen from the side room of the flower hall. After spreading out the rice paper and putting the paperweight in place, she began to grind ink for Shen Zheng.
Yu Jiusi, Zhuang Sijing, and Feng Qianzhi stood up together and stood behind Shen Zheng to watch her solve the problem.
They looked down and saw that the tip of the pen in Shen Zheng's hand was dipped in ink and then began to write -
What was written on it were characters that they could not understand. Only Yu Nanshu, who was grinding ink nearby, could understand a little bit, but she did not make any noise to disturb them.
For a moment, the only sound in the hall was the sound of pen tips sliding across paper.
Zhuang Quan also stared at the ink on the paper without blinking, but he didn't quite understand it from the beginning. He only knew that Shen Zheng seemed to... be making assumptions?
"All right."
Half a minute later, Shen Zheng raised his wrist to stop writing and put the brush back on the inkstone.
She signaled Zhuang Quan to look at the paper as well, and said, "There are three answers to this question: four roosters, eighteen hens, and seventy-eight chicks... Forget it, you can look at the remaining two answers yourself."
Xuan paper was turned to Zhuang Quanye.
Before, Zhuang Quan knew that this question had three answers, but he had no idea what the answers were.
Now Shen Zheng pushed the answer in front of him. He was stunned for a long time before saying, "I...well, I, let me calculate it."
The teachers at the Imperial College would take several days to solve the problem, but Shen Zheng solved it in just a quarter of an hour right in front of them?
This is simply impossible, Zhuang Quan comforted himself.
But on second thought, he couldn’t understand why the answer Shen Zheng calculated was also exactly three?
He just said "there is more than one answer", but he didn't say the answer is three, right?
Suppressing the almost impossible thought in his mind, Zhuang Quan walked out of the hall in unison, ready to get the abacus.
"Why are you still looking for an abacus?" Yu Nanshu picked up the brush and smiled at Zhuang Quan. "I can calculate this product on paper for you, cousin. Don't bother, our grandfather and the others are waiting for us to eat!"
"Product?" Zhuang Quan also paused, "Product of each other?"
Yu Nanshu even learned this in Tongan County?
"Yeah." Yu Nanshu smiled, "Cousin also knows that I am the most fair. Don't worry, if the answer matches, Sister Shen will allow you to take it back to show your teacher."
Then, under Zhuang Quan's increasingly dazed gaze, Yu Nanshu finished the last stroke.
"The answer is one hundred chickens and one hundred coins." She raised her chin and said proudly, "What do you think, cousin? The answer is three, right? Sister Shen didn't miss any."
Zhuang Quan also stared at the paper blankly, "How is this possible..."
Yu Nanshu frowned when she heard this. "Sister Shen has figured it out, so what else is impossible? Zhuang Quanye, you should accept defeat. Come to think of it, Sister Shen hasn't made a bet with you yet, so where's your wallet? Give it to me!"
I originally thought that Zhuang Quan would continue to argue, but I didn't expect him to simply pull off the purse and stuff it into Shen Zheng's hand.
"I won't eat lunch." He glanced at Shen Zheng, grabbed the rice paper on the table and ran away, "I'm going to find the teacher! Don't worry about me!"
