Chapter 9: The Puzzle

Lin Yueyue finally found the registration office for new students, registered, and found her class according to the signs.

I have to say that this academy is quite well built, Lin Yueyue's class is on the second floor, and there is a particularly big tree next to it. From their position, they could see the whole body of the tree.

Lin Yueyue found a place to sit down, there are very few people who learn arithmetic, it is estimated that there are only a dozen people in a class, and they are all boys!

Fortunately, they are all single seats.

The boy sitting next to Lin Yueyue glanced at her.

How can there be girls learning arithmetic these days?

Glancing at the pen on his desk, Lin Yueyue suddenly remembered that her stationery didn't seem to be prepared.

"Classmate, do you have any extra pens?"

Ha? This person comes to class without a pen? The man shook his head disdainfully: "Just one." ”

Lin Yueyue accepted her fate, and hoped not to write in the first class.

She can write calligraphy, there are clubs in modern schools, and she chooses calligraphy, and because of this, she also has the nickname of "Brush Girl".

Thinking of the unbearable past, Lin Yueyue took a deep breath and seized this opportunity to change herself! You can't be cowardly like you are today.

A bell rang from not far away, and it must have been a class bell.

Sure enough, as soon as the bell rang, the students who were still noisy suddenly quieted down.

A young man in white walked in.

Lin Yueyue recognized him as the one who had just shown the way.

She had some impression in her mind, it should be said that it was the impression of the original owner, but she couldn't remember it.

Xue Sheng glanced at the class and trembled when he saw Lin Yueyue.

Well, he resigned himself to his fate, and he only taught this one lesson anyway, and she couldn't make any sense of it.

After a brief introduction of himself and this subject, Xue Sheng began to talk about the basics.

The boy next to him muttered to another person: "Obviously only a few years older, the third prince is really different from ordinary people, and he has already become a father and son." ”

Lin Yueyue suddenly became big after hearing this, it turned out that he was the third prince! No wonder the people next to him looked at him with ill will when she asked for directions.

He wouldn't have thought she was looking for him on purpose, would he?

"I'll give you a difficult question first, you can write it down on a piece of paper and think about it."

When Lin Yueyue heard this, this was terrible.

Teachers have a common problem, that is, they like to wander around, and Xue Sheng is no exception.

"I don't know how many chickens and rabbits are in the same cage......"

When I turned to Lin Yueyue, I saw that her head was about to be buried in the table, and the whole person was on the table, and it looked like she was writing from a distance.

"Classmate, where's your pen?"

Lin Yueyue raised her head and whispered, "I forgot to bring it." ”

Xue Sheng frowned, he didn't bring a pen to class, so what are you doing? Come and play?

Still is...... She knew in advance that he was coming for a class, and happily forgot to bring stationery?

This woman is really getting more and more courageous.

"Next time, pay attention, you can watch mine." Xue Sheng handed her the question he had written.

Lin Yueyue took a look, chickens and rabbits in the same cage?

"I don't know how many chickens and rabbits are in the same cage, thirty-six cages are exposed, and there are fifty pairs of feet, how many chickens and rabbits are there?"

After Xue Sheng finished reporting the topic, the students thought about it seriously.

Lin Yueyue was stunned, is this a topic in elementary school or junior high school? What the hell does it call a puzzle?

On second thought, this is ancient times, and there are no unknown numbers in ancient times.

Xue Sheng couldn't help but be a little annoyed when he saw that Lin Yueyue seemed to be in a daze.

He was most annoyed by this kind of not studying hard and had to come to make up the number, plus the previous bad impression, Xue Sheng decided to embarrass her.

"Lin Yueyue, have you thought about it? Tell your classmates what you think. ”

Lin Yueyue got up, looking embarrassed, how could she explain this question in a language they could understand?

In Xue Sheng's opinion, she showed this embarrassed expression because she didn't know, thinking if she would go too far?

Just as she was about to sit her down, she spoke.

"There are two solutions to this problem." (The two solutions naturally come from Baidu.) )

Hearing her say that there are two solutions, Xue Sheng became interested: "You can explain it." ”

"The first is the foot cutting method, pretending that we cut off the rabbit's two feet, then it only has two feet left."

Lin Yueyue always felt that what she said was weird, would it be too long-winded?

If the rabbit cuts off two legs, there are no two left, is it possible that there are three or four left? Why did she have to tell this common sense?

Lin Yueyue subconsciously glanced at the teacher, and Xue Sheng motioned for her to continue.

"So now there are a total of 72 legs, and there were originally 100, so a total of 28 rabbits were cut off, so the rabbits should be 14 and the chickens are 22."

After listening to her, everyone was still a little confused, how did they get rabbit 14 and chicken 22? Do you dare to go into more detail? T_T

Lin Yueyue said: This is detailed enough.

Xue Sheng thought for a while, he actually didn't understand her train of thought yet, and it seemed that he would have to study it again when he went back.

"And what about the second method?"

Everyone has learned from the past, and immediately holds the pen in their hands, and it is bound to write down every word she says, and then figure it out!
