Chapter 75 What city is Fangcheng?
The students watching in the audience were still thinking about the problem of pheasants and rabbits in the same cage.
"Thirty-five heads...ninety-four legs..." Someone raised his legs involuntarily while counting.
Zhu Qingyan was naturally also present.
Her grades were among the best among students of the same age at Longchang Academy, and she prided herself on being well-read and versatile, but when faced with a subject that required solving practical problems, she was at a loss.
Zhu Qingyan was secretly anxious and kept blaming himself for not being able to solve even this kind of problem.
Finally, she looked around and her eyes fell on Zhu Lan.
With such a difficult question, she must be confused, right?
Zhu Qingyan secretly glanced at Zhu Lan's expression, trying hard to find some signs of being stumped on her face, but unfortunately he failed.
I felt even more anxious.
The difficulty of the topics selected by Ouyang Ye increases from easy to difficult. Now I will start reading the third question.
"There is a person who lends 1,000 coins and the monthly interest is 30. Now there is a person who lends 750 coins and returns it in nine days. How much is the interest?"
For modern people like Qiao Youyou who have experienced the college entrance examination, this question is a very simple interest calculation problem.
Of course, Fang Xiucai has faced many such problems and his ideas for solving them are very clear.
He wrote down the problem, immediately picked up the abacus chips on the table, and began to arrange them one by one on the table.
But then he was stunned for a moment, because it was obvious that the number of counting chips prepared was not enough.
Fang Xiucai immediately looked up and said to Ouyang Ye: "Please suspend the game, I don't have enough chips!"
Ouyang Ye was also a little surprised, because these counting chips were found directly from the academy's warehouse.
Since the college does not offer mathematics classes, no one has used this thing for a long time. It is possible that a lot of it was lost when things were moved from the warehouse.
The counting sticks were divided equally between Fang Xiucai and Qiao Youyou. Since Fang Xiucai said it was not enough, then Qiao Youyou should not have enough either.
Ouyang Ye looked at Qiao Youyou, but found that she didn't react at all. She lowered her head and wrote and drew on the paper, and didn't even touch the abacus.
At this time, Qiao Youyou also heard what Fang Xiucai said, raised her head and blinked.
Oh, it turns out that thing on the table is counting chips. She thought it was chopsticks.
"If it's not enough, you can take all of mine."
As he said this, he pushed the abacus on his desk forward.
She doesn't know how to use this thing anyway.
Mr. Fang was stunned, as if he had seen a ghost.
He stared at Qiao Youyou for a long while before he stammered, "You...you don't need to count?"
Qiao Youyou waved her hand, "No need, no need."
Mr. Fang put the two men's counting sticks together, and that was enough, but he was confused and upset.
Why doesn't she use counting rods for such a complicated calculation?
How to calculate without counting rods?
Could it be that she is a god who has descended to earth?
While he was struggling, Qiao Youyou had already put down her pen and gave the answer.
"The interest is three-tenths of six thousand four cents."
Mr. Fang opened his mouth in surprise and the abacus in his hand fell to the ground.
"Yes, that's consistent with the answer." Ouyang Ye said.
The students below were in an uproar.
"Did you see that Qiao Youyou? She didn't even use counting sticks!"
"What, what happened? She just drew a few strokes on a piece of paper and figured it out?"
"Impossible, it's fake, absolutely fake!"
"What's fake? Didn't you see Ouyang Jiabei nodded?"
"I don't believe it, she must have used some kind of witchcraft!"
Ouyang Ye couldn't help but look at Qiao Youyou twice more, with a bit of surprise and admiration in his eyes.
"Question 4—"
"No need." Mr. Fang lowered his head in defeat. "I lost."
If he continues to compete, he will only bring shame upon himself.
Qiao Youyou was very proud and gave a "yeah" gesture to Zhu Lan and Qin Yuwei in the audience.
Finally, I can open a mathematics club!
The two of them also gave her a "heart" in response.
Ouyang Ye walked up to Mr. Fang and thanked him politely, thanking him for helping Longchang Academy organize this competition.
And he said that the academy would pay him.
Mr. Fang shook his head, his mouth drooping.
"I...I don't want any reward."
Then he pointed at the paper on Qiao Youyou's desk and said that he wanted to see what Qiao Youyou had written on the paper.
Ouyang Ye asked Qiao Youyou for her opinion. Of course Qiao Youyou didn't care as long as he could understand it.
Fang Xiucai took the draft papers from Qiao Youyou with both hands, his eyes pious, as if he was holding something holy.
The next moment his eyebrows frowned.
What kind of things are being painted?
Could it be that she really used some kind of magic?
But this pile of stuff looks different from the talismans in the Taoist temples.
Could it be some kind of new sect?
"That's called an equation." Qiao Youyou explained seriously.
Fangcheng...what city is it? Mr. Fang had never heard of this place.
He put down the thing that looked like a heavenly book in his hand, with a strange expression on his face, as if he was very conflicted.
After hesitating for a while, he suddenly made up his mind and strode towards Qiao Youyou.
Qiao Youyou was so scared that she took two steps back. What was this guy doing? Was he going to fight because he couldn't win?
Mr. Fang walked up to Qiao Youyou and stood in front of her. Suddenly, he clasped his fists and bowed deeply, his waist almost bending to the ground.
"Please...please teach me!"
He laid his cards on the table and stopped pretending.
He wants to learn this "Fangcheng"!
Qiao Youyou licked her lips, feeling a little awkward about being treated with such a big gift.
She turned her gaze to Ouyang Ye, "Dean Ouyang, can I now establish a mathematics club?"
Ouyang Ye pondered for a while. Although he already believed that Qiao Youyou had the ability to do so, he was afraid that now was not a good time.
After all, this year's college entrance examination is about to begin.
With the current level of Qiao Youyou's students, they are ready to test the waters, and he does not want these children to be distracted at this critical juncture.
"If you can pass the college entrance examination, this dean will allow you to start a club in the academy."
Huh? Qiao Youyou was a little disappointed.
Unexpectedly, Ouyang Ye put forward new conditions.
She still wanted to fight for it, but looking at Ouyang Ye's expression, she knew that the decision he made would not be changed.
After the competition, students began to leave Wulei Pavilion one after another.
Qiao Youyou, Zhu Lan and others complained as they walked.
"Humph, Ouyang Jiabei, that stinky old man! He doesn't keep his word!"
As they were talking, Mr. Fang caught up with them from behind.
He still really wants to learn that "formula".
Qiao Youyou spread her hands and said, "You can see that I am just a student of the academy. You can't come to the academy to see me every day."
"I also want to open a mathematics club in the academy, but you have heard the dean's conditions.
I, too, must pass the examination to become a scholar, just like you."
Qiao Youyou looked up at the sky with melancholy. She didn't want to study that much, so she wanted to set up a club and find something interesting to do.
As a result, if you want to run a club now, you have to study hard.
Help!
"If there is a mathematics society, can I come and study there?" Fang Xiucai looked expectant.
Qiao Youyou nodded, of course!
She is not one to be stingy with knowledge.
When Mr. Fang got the answer, his eyes immediately started rolling.
