Someone on the side suddenly shouted: "This family is too stingy. Two people share one rice bowl. How can we eat this?"
Committee Yang made a dark line: "Why do you ask so many questions? I ask you to do the questions, and I don't ask you to discuss whether someone's family is stingy or not."
Zu An smiled slightly. He couldn't understand why Committee Yang found such a simple question difficult? If it can be solved with just one equation, could it be that people in this world don't know how to multiply two-digit numbers?
He made a casual gesture and wrote down 60 guests.
Gulu~
Yang Wei swallowed hard. How is it possible? Does this guy know the answers? But these questions were asked by me.
Are these questions really easy?
He was a little doubtful about life. It wasn't until he saw the blank faces of other students around him that he regained his balance. This guy must have guessed. He just happened to be the first one to try the number 60. Well, that must be the case.
Zu An continued to look at the third question:
In Mingyue City Market, a rooster is worth 5 yuan, a hen is worth 3 yuan, and three chickens are worth 1 yuan. Now a peasant woman buys 100 chickens for 100 yuan. How many roosters, how many hens, and how many chicks did she buy in total?
?
Hey, this is interesting. There are three unknowns, but only two equations can be formulated.
However, the number is not big, so we can exhaustively enumerate it. Of course, it is not a stupid exhaustion, but a strategic one. Assume that the rooster, hen, and chicken are xyz, and simplify the equations. We can deduce y=(100
-7x)÷4.
Because chickens are living animals, the number cannot be a decimal, so x, y, and z must all be integers. Therefore, the number X of roosters must be an even number, so that 100-7x can be divisible by 4.
Starting from 2, you can quickly get 4 roosters, 18 hens, and 78 chicks.
Seeing that he had written the answer, Mr. Yang's mind went blank. Three questions had been asked, and he had already answered three questions correctly!
Even if he wants to rely on the authority of the teacher to say that the other person's answer is wrong, it won't work, because in front of everyone, although these people may not be able to do it, it is easy to verify whether it is correct by working backwards from the answer, not to mention there is a businessman.
Leave the fish here and watch.
What on earth is going on with this guy? Isn’t he a waste? How can he solve these problems so easily? And he can solve them much faster than him?
Now that the other party answered three questions correctly, his bet has been lost. Now he no longer expects to drive the other party out, but hopes that he will not get them all wrong. Then it will be difficult for him to step down.
You must know that he had never thought of such a situation before, so he made a promise casually, but now this posture made him panic.
Don't be afraid, the following questions are getting more and more difficult, especially the last question, which I found in an ancient and unique book. Not to mention the student, even he himself couldn't do it.
No matter how powerful this guy is, there has to be a limit. How can he solve such an ancient problem?
However, Zu An was quick and easy, writing out the answers to questions one after another, causing people around him to exclaim. At first, everyone, like Commissioner Yang, thought he was a blind cat who encountered a dead mouse.
, but now that everyone is not blind, they naturally understand that he is really an arithmetic genius.
Everyone originally planned to watch Zu An's joke. After all, this guy married the most beautiful Miss Chu and flirted with so many school beauties in the beauty album. It really made people hate him so much that everyone wished he would be kicked out.
Leave the academy.
But now that things have developed, not only are everyone not disappointed, but they are getting more and more excited. Watching students being kicked out of the college is not as interesting as seeing teachers being kicked out of the college.
Shang Liuyu also had a faint smile on his lips, looking at Zu An who was concentrating on writing, thinking that this guy is quite handsome when he is serious.
Involuntarily thinking of the scene of their first encounter in the pavilion, Shang Liuyu's eyes became more and more curious: How many secrets does this guy have?
Unlike Shang Liuyu who was relaxed, Yang Wei kept wiping the cold sweat on his forehead with a handkerchief. He could clearly feel the eyes of everyone in the venue gradually moving towards him. He felt a little frightened in his heart, so he had to keep
Comfort yourself: "Don't panic, he will never be able to solve the last question."
At this time, Zu An also stopped in front of the last question:
"Two peasant women brought a total of 100 eggs to Mingyue City Market to sell. The money they sold was the same. The first peasant woman said to the second peasant woman: 'If I had as many eggs as you, I would
It can be sold for 15 pieces of silver.' The second peasant woman said, 'If I had as many eggs as you, I could only sell them for 6 and two-thirds of money.' How many eggs do they each have?"
The surrounding students immediately started talking:
"Strange, why do two peasant women sell the same eggs at different prices?"
"Isn't this normal? It's obvious that one of the two peasant women is good-looking and the other is ugly. The good-looking one is sold at a high price but some people buy it. The ugly one can only sell her eggs cheaper."
"Brother, thank you very much!"
…
Zu An was stunned when he saw this question and looked at Yang Wei: "Do you think this question is difficult?"
Yang Wei thought nonsense, if it wasn't difficult, why should I stay in the last line? But at this time, he no longer dared to look down on the other party, so he could only say ambiguously: "It's not difficult for me to meet."
"It's really not difficult." Zu An thought that this was a problem of formulating a system of equations, with four unknowns and four equations, but the solution process might be a little more troublesome.
But Yang Wei was so angry that he thought I was just being polite, but you ended up kicking your nose in the face? Let me see if you can do it!
The anger value from Committee Yang is +222!
Zu An looked at him strangely, made some rough sketches on the paper, and finally wrote the answer: The first peasant woman had 40 eggs, and the second peasant woman had 60 eggs.
Someone who had done something good had taken the answers back to check and immediately shouted: "You did it right, you did it right! All 20 questions were correct."
Everyone in the classroom was shocked and looked at Mr. Yang with strange expressions. He had just said in the bet that if the other party could get all 20 questions correct, he would quit his job.
Yang Wei's head was buzzing at the moment. Everything that happened today really went against common sense. He originally thought he was just accepting an easy task and stepping on a useless student, but he didn't know that the other party actually put him in a dilemma.
There's something wrong with this plot. Didn't the intelligence say that he was a famous loser in the city? Why is he so good at arithmetic?
Zu An looked at the graceful Shang Liuyu and asked with a smile: "Teacher Shang, right? You are the referee, who do you think won?"
"Of course you win." Shang Liuyu nodded, showing a smile that only the two of them could understand.
Zu An then looked at Commissioner Yang: "This Teacher Yang, right? Someone just seemed to say that if I got 20 questions correct, he would resign automatically. I don't know if it still counts?"
Yang Wei's face turned red, and his middle-parted hair trembled: "You cheated! Yes, you must have cheated!"
At this time, he no longer cares about embarrassing himself in front of the goddess. The main thing is to keep his position. Otherwise, he will become the first teacher in the history of the Zhou Dynasty to be kicked out of class by students. He cannot afford to embarrass this person.
"Cut~"
There was a loud boo in the classroom, obviously everyone was dissatisfied with his rogue behavior.
Shang Liuyu also frowned slightly and couldn't help but said: "Teacher Yang, everyone is watching the whole process here, how could he cheat."
As if he could feel the disdain in the goddess's eyes, Yang Wei smoothed the hair in front of his forehead and said hurriedly: "I remembered, I can actually guess these questions if I'm lucky, and the values are not too big. He can definitely do it.
Try the answers one by one."
"Look at the steps he wrote, can you understand them? Obviously he was just guessing."
Some students carefully looked at the processes on Zu An's test paper and nodded with deep sympathy. They really couldn't understand. Could it be that they were really guessing? This must be great luck, right? But I heard that he had gambled in Silver Hook before.
Fang won 7.5 million taels in two games. There is really no luck in terms of luck.
Zu An couldn't help but shook his head: "Although I knew you were shameless before, I didn't expect you to be so shameless. You can tell lies with your eyes open in front of so many people. Just say what I just did."
Are all of these correct?"
"What's the point of having a right answer? If there is no process, it's still zero points." Yang Wei said bravely, "This is the rule of the arithmetic class. The main purpose is to prevent those who plagiarize the answers and blind cats like you from encountering dead mice.
"
Shang Liuyu on the side chuckled and said: "Teacher Yang, what you said is a bit wrong. Even if he is lucky enough to guess one or two, he can't guess all 20 questions. Is this the method he uses?
It’s too novel, you haven’t seen it before?”
She is very beautiful and has a graceful temperament. Even though she speaks a few words softly, she gives almost everyone a sense of recognition:
"Teacher Shang is right!"
"It really can't be such a coincidence."
…
Yang Wei's eyelids twitched, and he couldn't help but feel secretly angry. Is this woman sincerely against me? When it comes to position and reputation, he doesn't care about any goddess.
His face darkened: "Teacher Shang, you teach foreign languages. I don't blame you for not knowing arithmetic. The messy steps he wrote are not for me, not even for the arithmetic teachers at the Royal National College in Beijing."
It's impossible to understand. There is no such solution in the world. I said he was just guessing, so what's the problem? If you don't believe me, ask him to explain what these steps are."
He had already made up his mind in his mind that no matter what the other party said was reasonable or not, he would directly criticize it as nonsense. This battle had already blocked his lifelong reputation, and he could not care less about his appearance.
Shang Liuyu frowned slightly. After all, the other party was a well-known arithmetic expert in Mingyue City. His words had great authority, and he didn't know how to help.
She had no choice but to look at Zu An aside. This young man had given her too many surprises. She didn't know how he would respond this time.
Zu An said calmly: "With your attainments in arithmetic, you won't understand even if I explain these processes."
Yang Wei laughed angrily: "Haha, did you hear what this arrogant boy said? I have never seen such a arrogant student in my life. I must report it to the school and expel you to correct the school spirit!"
