Imperial College Kindergarten

"A group of crows are perched on a tree, but there are no number of crows on the trees. Three are sitting on one tree, but five are nowhere to go. Five are perching on one tree, and one tree is free. What are the crows and the trees?"

After waiting for a while, seeing that no one had a clue, Liu Xueting broke it down step by step: "Can anyone tell me why I assume there are x crows and y trees?"

Sheng Lanting was the first to raise his hand and said: "I know, because we don't know how big the crows and trees are!"

"That's right, you reacted so quickly!" Liu Xueting gave a thumbs up, "We have said before that when you don't know a number, you can set the unknown number and replace it with x. What if there is another unknown number? What? We can replace it with another unknown number y."

"Now if you look at the formulas I listed, do you understand what they mean?"

Fu Heng suddenly realized: "Oh! I understand!"

"Then please ask Fu Heng, kid, to share his thoughts with us?"

Fu Heng stood up and said seriously: "With three crows sitting on a tree, we can get 3y, and there are still 5 crows left, so we need to add 5 crows to equal the number of all crows, so we have the formula 3y+5=x. In the following formula, there are 5 crows."

Seeing that Fu Heng was hesitant, Liu Xueting asked him to sit down first and gave him an appreciative look: "Fu Heng has said the complete meaning, which is great!"

"Does anyone know the meaning of the following expression?"

The commander also raised his hand: "There are 5 crows on a tree, so you have to multiply the number of trees with 5, so it is 5y!"

"No, if you read the question, there is already one tree free, so...ah! Yes, the remaining tree does not have 5 crows, so you have to subtract 5 to get the number of crows!" Wang Lingxi quickly reacted. .

"Smart, I quickly discovered where 5y-5 came from."

"3y+5=x, 5y-5=x, children, have you discovered that there is a little secret waiting for us to discover?" Liu Xueting continued to ask.

Xue Bo frowned and thought for a while, then said loudly: "They are all equal to x in the end!"

"Xue Bo's observation is so meticulous. He discovered this little secret so quickly! So since they are all equal to x, can we list them like this?"

Liu Xueting asked the next question and listed a new equation on the rice paper - 3y+5=5y-5.

"Next, please use the method I taught you before to solve it!"

Before the exchange meeting, she taught everyone a mathematical method, and there was no problem in solving this equation.

After a while, Sheng Lanting calculated y=5.

Immediately afterwards, Fu Heng also gave the number of crows, 20.

In the end, when everyone could figure it out, the bell just rang.

Liu Xueting quickly ended the class and was arranging the lesson plan with his head down.

Naturally, she didn't notice how caring Xie Yu's eyes were on her.

When Liu Xueting raised his head as if feeling something, Xie Yu had half-closed his eyelids, and his slightly long and thick eyelashes covered all his emotions.

Xie Yu spread his hands, looked down at the palm that had been pinched by him, and smiled bitterly in his heart. It had to be said that he still couldn't turn a blind eye to her.

Especially when she was in arithmetic class, he could only be firmly attracted to her, unable to resist.

But what else could he do?

got rejected.

Liu Xueting sat back on the teaching assistant's seat. The afternoon class was over and the children had all walked out of the classroom. Only Xie Yu remained in his seat, as if he was looking at something in a trance. "Thank you, assistant teacher?"

Xie Yu came to his senses, nodded slightly, stood up and walked out of the classroom quickly.

"Tong, what do you think Xie Yu is doing?" Liu Xueting couldn't help but ask.

303 didn’t know either: “You can just ask him directly!”

"I..." Liu Xueting hesitated for a while, "I mean, after the melon-eating value is accumulated, what will happen if I return to this modern body?"

"The original owner was dead before you came, and it will be the same after you leave."

The answer of 303 made Liu Xueting's shaken heart firm again. She sighed, but in the end she didn't chase him out.

After a delay, when Liu Xueting walked out of the Imperial Academy, there were not many people there.

Seeing Xie Yu's figure disappearing at the corner of the street from a distance, she stopped moving forward and turned around to walk to another street.

When she passed by a shop selling lanterns, large and small lanterns were hung on the bamboo shelves displayed at the door. When the breeze blew, the lanterns rippled gently. Liu Xueding was attracted by this and stopped.

A waiter happened to take out a new lantern. Seeing Liu Xue stop and watch, he hurriedly greeted: "Guest, haven't these been sold yet?"

"Oh?" It was put up and it didn't sell yet?
Liu Xue became interested when she paused.

"Isn't it the Mid-Autumn Festival in two days? We won't be able to sell them until the Mid-Autumn Lantern Festival!"

She was stunned in place, was it almost the Mid-Autumn Festival?
time flies.

After wandering around aimlessly for a while, Liu Xueting went back to the small courtyard. When he walked to the door, he saw someone coming, yo, a rare visitor!

Li Shuning was already impatient with waiting, and secretly scolded Liu Xueting several times in her mind. When Liu Xueting finally appeared, she couldn't help but ask, "How did you train this servant to not even understand any rules!"

Her majestic Madam actually asked her to wait outside!

The smile on Liu Xueting's face remained unchanged, but there was not much true feeling in it: "I don't know if Mrs. Hou is coming here, but she is not welcomed from afar. Uncle Ma and the others are sent by my eldest brother."

"You!" Li Shuning looked grim. She had been estranged from her for how long since her eldest son came back. Now that Liu Xueting brought it up again, he was simply digging into her heart!

"I have something to say, why don't you invite me in!" But Li Shuning thought that the purpose of coming here had not yet been achieved, so he made an excuse first, but his tone was still a little arrogant.

"Mrs. Hou, my courtyard is small, so I'm afraid the reception is not good enough." Liu Xueting lowered his eyes, but he couldn't guess what Li Shuning wanted to do after going through it in his mind.

Unexpectedly, Li Shuning covered the corners of her eyes with a handkerchief and cried twice: "Xue Ting, no matter what, the Hou Mansion has raised you for 13 years. Even if you pay back the upbringing fees, how can the relationship of so many years be worth it?" Did you mean to cut it off?"

"How do you say that? It's not as good as nurturing kindness. The relationship we have had for so many years is closer than the blood relationship! Not to mention, you are still my sister's child. My grandparents are also looking forward to your return. Going to the house!"

"In my mother's heart, you are no different from Qingyan. You are also my daughter!"

"The Mid-Autumn Festival will be here in two days. Why don't you go back home and let us all have a lively Reunion Festival?"

"When you return to the Hou Mansion, you will still be the rich daughter of the Hou Mansion, and you will be treated the same as Qingyan. It is better than being alone outside, right?"

Liu Xue stopped listening and frowned unconsciously. This sudden tone of wanting to recognize her was going to cause a big stir? (End of chapter)
