Hanuo and Sang Mu were making a bet, and Chai Yan was also explaining the meaning of "strange symbols" to the three Yuan people...
Chai Yan took the pen and wrote on the paper: "Now, let me teach you these Arabic numerals first. One is like a chopstick, two is like a duck, three is like drawing an ear...
"
"Sir, why are they called Arabic numerals?" Guan Maochun's problematic baby characteristics showed up again. As soon as he wrote three numbers, he interrupted Chai Yan: "What are Arabic numerals?"
Chai Yan didn't want to answer at first, but Yuan Yuan and Cheng Jiu also looked at him with puzzled faces.
"Uh, this, this..."
Chai Yan frowned and thought for a while, then said with a serious face: "This Arab is actually a person. His name is Allah. Because of his age, others affectionately call him Arab! It was he who invented this
This number looks strange but is very useful, so we call it Arabic numerals! Can you understand what I say?"
Guan Maochun took the lead in nodding, and said curiously: "It's so strange that someone calls a name like Ala..."
"What's so surprising? Do you know what it means that the world is so big and full of wonders?" Chai Yan immediately complained.
Suddenly, Chai Yan heard Shangguan Peining's voice: "Chai Yan, Chai Yan, you are really good at making up nonsense. You just open your mouth and come up with nonsense!"
Chai Yan knew what Shangguan Peining meant, and helplessly thought to himself: "What else? Do I have to tell them that Arabia is actually a country, and that Arabic numerals were not invented by Arabs, but by ancient Indians?
It was later spread to Europe by the Arabs, and then the Europeans modernized these numbers. Then people thought they were invented by the Arabs, so they called them Arabic numerals?"
After Chai Yan finished speaking quickly, he continued: "If I tell the truth, I don't have to explain what Arabia is, what India is, what Europe is...it is originally the center of this world.
How do you ask me to explain something that doesn't exist? Can I explain it clearly?"
"Tsk, you are right to say that..." Shangguan Peining thought that it was right. If he could not read Chai Yan's thoughts and understand these contents clearly, otherwise those Arabs, Indians, Europeans, etc.
, even if you listen to it, you won’t be able to figure it out 80% of the time.
Seeing that Chai Yan was suddenly in a daze, Yuanyuan waved his hand twice in front of his eyes and asked, "What's wrong with you? What are you thinking about?"
Chai Yan came back to his senses and said hurriedly: "Ah...it's okay, it's okay, let's continue..."
"Where did I just say... Oh, yes, I remembered it. I said three, and then four... Well, if you make two strokes, does it look like a sail from a distance?
?”
Next, Chai Yan not only explained the Arabic numerals from zero to nine, but also explained the symbols for addition, subtraction, multiplication, division and equals, and finally talked about the linear equation of two variables just now.
"Suppose there are
, this is a representative symbol, as long as you know it!”
Guan Maochun's mouth was already open, but after hearing what Chai Yan said, he obediently closed it again.
Chai Yan continued: "After the assumptions are made, the number of benches and bronze tripods can be written as
We get X=1, Y=32, which means one bench and thirty-two bronze tripods... Done!"
After Chai Yan finished explaining, he looked at the three Yuan people with a smile, as if to say that everyone should understand now, right?
Guan Maochun turned to look at Cheng Jiu and asked in a low voice: "Fourth brother, do you understand?"
Cheng Jiu hesitated slightly, but finally shook his head: "No."
Guan Maochun looked at Yuan again: "Chai...Um, Mr. You, what about you?"
Yuan Yuan said truthfully: "I understand some, but not all..."
Chai Yan said: "It's normal that you didn't understand it all at once. The amount of knowledge involved is huge and cannot be digested overnight."
As soon as he finished speaking, a gong sound of "boring" sounded on the stage.
Chai Yan then asked: "What time is this? I was talking to you just now, but I didn't even pay attention..."
Yuan replied: "This is the third sound."
Chai Yan nodded and said: "Just right, let's see the result!"
With that said, Chai Yan and the others turned their attention to the stage.
At the same time as the gong rang, Hanuo behind him was looking at An Huai with a sullen expression...
Sang Mu, who was at the same table, had a smile on his face: "Hanuo, thank you for the wine..."
Hanuo glanced at Sang Mu and said in a low voice: "What are An Huai and the others thinking? No matter what, you must submit an answer, even if it's just a blur..."
Just now, Sha'er Zidan's table handed in their answer sheets in time before the third gong sounded, but An Huai's side remained silent and watched helplessly as the last gong sounded.
An Huai didn't know that his grandfather and Elder Sang Mu were betting on this matter. If he had known about it, even if he hadn't calculated it, he would have written an answer and submitted it.
Now only Shaer Zidan of both parties has handed in the answer sheet, and the outcome of the bet has been decided!
The man took two steps forward and said loudly: "Everyone, let me announce the correct answer to this question..."
Hearing this, the noise in the hall quickly dropped. It seemed that everyone wanted to know the correct answer.
The host said loudly: "There are thirty-three benches and bronze tripods with one hundred legs facing the sky. The correct answer is...one bench and thirty-two bronze tripods!"
As soon as the answer was announced, the noise in the hall became much louder, and many people couldn't help but check the correctness of the answer.
Hanuo and Sang Mu couldn't help but check it in their minds, and it turned out to be true.
On the stage, the host had already picked up a piece of answer paper and showed it to everyone in the audience: "This is the answer paper handed in by Mr. Chai at the table first. It says bench one, copper tripod thirty-two. The answer is correct."
..."
Then, the host showed another answer sheet: "This is the answer for Sha'er Zidan's table. It says that the bench is ten and the bronze tripod is twenty...Obviously, this answer is
That’s not right…”
After putting down the answer sheet, the host announced: "So, the winner of this round of purple gems is Mr. Chai's table!"
As he said this, the host applauded, and the applause in the hall also rang out. This time it was louder than last time.
Watching the young man on the stage deliver the purple gem in front of Chai Yan, Hanuo couldn't help but feel a little tight in his chest.
Turning around and looking at Sang Mu, he seemed to be still laughing. He couldn't help it anymore and said in a deep voice, "You can still laugh when others steal the show!"
Sang Mu turned around and said: "If you don't laugh, why are you crying? Our people are not up to par, and we are not as smart as others. Who can blame us?"
