Although Kathleen only officially joined Liangfeng's family today, the impact of her arrival is already obvious.
"Hey, Liangfeng, come and play..."
"Hey, Liangfeng, come and lick your fur."
"Na, na..."
"..."
Liangfeng rubbed his eyebrows. Under Kathleen's interruption, Liangfeng finally finished his holiday homework. Now Liangfeng continues to study patiently.
The helpless cool breeze lifted Kathleen from the ground and placed her on the desk.
"Kathleen, do you know the Pythagorean Theorem?"
"?"
Kathleen tilted her head with a puzzled expression.
"The sum of the squares of the two right-angled sides in any plane right triangle must be equal to the square of the hypotenuse..."
Liangfeng took out a piece of A4 paper and wrote some drawings. He drew a triangle and then wrote the official title of Pythagorean Theorem.
"In △ABC, ∠C=90°, then a2+b2=c2, this is the Pythagorean theorem."
"Is this important?" Kathleen asked.
"The Pythagorean Theorem is actually very simple. You only need to learn very simple operations and understand the basics of geometry. However, such a simple thing is called the 'cornerstone of geometry', and it is also widely used in advanced mathematics and other subjects. Application. If you want to learn geometry and mathematics well, you must learn the Pythagorean Theorem."
"But I don't want to learn geometry, nor do I want to learn mathematics." Kathleen asked doubtfully.
Liangfeng looked at Kathleen with a calm expression.
"Do you understand?" Liangfeng asked.
Kathleen's cat face wrinkled.
"What do you understand? What do you understand?"
"So, you don't understand." The pen in Liangfeng's hand pointed at the A4 paper on the table, "This is a point, but when more such points are connected together, it will become a line. When lines are laid together, they become surfaces, and when the surfaces begin to move in space, they form bodies. Whether it is me or you, we can all be said to be bodies. However, the essence of bodies like ours is composed of small pieces. Made up of small dots.”
"We will do many things and make many choices, but nothing is unfounded. When we can't find the reason broadly, we can trace the source and look for it in each of the points that make us up. The answer, this represents the importance of the foundation and the original. The more we explore the grand, the smaller we will feel. But the more we study the subtle, the better we will understand ourselves. Only by truly understanding ourselves can we ensure that we do the best we can. The judgments made will not fall into misunderstandings.”
"Whether it is now or in the future, whether it is me or you, if you want to truly understand yourself and grasp your future, you must understand, and if you want to understand, then we need a tool, and the so-called The tool is mathematics, and any problem can be explained by mathematics. Only if you learn mathematics well, can you and the future go further, get what you expect, and reduce the risks of accidents."
Liangfeng's series of words stunned Kathleen, not because she was shocked, but because she didn't know where to start, and Kathleen couldn't follow Liangfeng's train of thought.
but……
Should I let Liangfeng know if she understood?
What if Liangfeng hates me for this reason?
so? Just tell a lie.
"Yes, I understand." Kathleen nodded confidently and said.
As expected, a smile appeared on Liangfeng's face, and Kathleen felt inexplicably happy.
Then, Kathleen saw Liangfeng take a book from the bookshelf and put it in front of Kathleen.
"What is this?" Kathleen asked.
"This is a math book." Liangfeng lost. "Now that you understand, let's learn math from today on. Learning math will make you grow further. Don't worry, I will teach you. I hope you won't Let me down, you can become an excellent and admirable existence in the future, and I will always be by your side."
"???"
Kathleen didn't understand why the topic directly touched on the Pythagorean theorem and jumped to learning mathematics, but...
"Become an excellent and admirable being, and the cool breeze will always be by my side..."
Kathleen's heart felt like honey.
Well, I learned it!
Liangfeng smiled.
Can you become stronger by studying math?
If there was such a good thing, Liangfeng would have learned calculus long ago.
Learning mathematics only makes people better. Mathematics can solve problems in natural sciences, but it cannot solve problems in social sciences. Obviously, what happened between Liangfeng and Kathleen, as well as Kathleen’s own affairs , definitely not natural science.
In fact, Liangfeng didn't know what he was talking about. He was just trying to trick Kathleen into learning mathematics so that she would stop annoying him so much.
But there are two things Liangfeng did not lie about, that is, if Kathleen is willing, Liangfeng can indeed teach Kathleen, and Liangfeng will always stay by Kathleen's side, after all...
You can't let Kathleen leave Liangfeng's sight easily. Liangfeng won't be worried if a cat runs out like this.
Kathleen opened her math book.
But Liangfeng didn't embarrass Kathleen. What he gave Kathleen was a math book from his childhood. It talked about very basic things. As for whether she could learn it...that was not Liangfeng's control.
Although Kathleen has been living in that strange place, Kathleen still has basic common sense, and she is also literate and knows the English alphabet. I heard that these things were taught to Kathleen by the pig-headed butler.
It was also because Kathleen had a good foundation that Liangfeng did not directly give Kathleen a first-grade math book, but a fifth-grade math book.
In this way, Kathleen read the math book quietly, and Liangfeng finally had time to review the knowledge points from last week.
During dinner, when Liang's father opened the door and found Liangfeng and Kathleen, he saw one person and one cat reading quietly. Liang's father almost thought that he had gone to the wrong place.
Can cats read books?
Damn it!
Liangfeng also stopped studying, but when Liangfeng noticed that Kathleen was also reading seriously, her expression still became very strange.
After the meal, Liangfeng began to communicate with Kathleen.
"Can you understand?"
Kathleen nodded.
"How much have you learned?" Liangfeng asked tentatively.
Kathleen patted the textbook and said that she had finished studying the main book.
Although there is not much content in primary school mathematics books, Liangfeng was a little surprised that Kathleen read the entire mathematics book in one afternoon...
It would be okay if she was a normal girl, but this is Kathleen, not a human being.
Liangfeng picked up the math book, selected a chapter, and opened the after-school exercises.
"Try these questions and I'll check them later."
Katherine looked confident, held the pen between her two paws, and began to write and draw on the A4 paper.
Soon, Kathleen presented the answer.
Liangfeng picked up Kathleen's answer and looked at the reference answer...
"All, all right...?!"
Liangfeng looked at Kathleen, her face gradually became strange.
The plot shouldn't be like this.
Katherine was very happy and rubbed her neck against Liangfeng's arm.
"It's time, let's go to bed. I want to give you some rewards for working so hard." Kathleen said coquettishly.
"..."
