I Just Want to Deliver a Normal Takeout

What physics, chemistry, mathematics...

In fact, they have a lot in common. As long as they can understand the origin, then Chen Feng will only need to take on the role of coaching in many subsequent studies, and the specific deduction and planning will be handed over to his own group of 'students' .

Originally, Chen Feng thought that his teaching process might be quite bumpy, but who knew that the Nakano sisters were not distracted, and listened to him telling stories about various knowledge seriously one by one, and they summed it up by themselves Something not quite.

When it comes to the simple Pythagorean Theorem, Chen Feng deduces and proves the stories of "cutting the circle" and "presidential proof" and many details in front of the Nakano sisters step by step.

Hook three strands, four strings and five strings, you can change it in any country, as long as people who have studied mathematics a little bit know this thing, but who in the middle can completely deduce and prove this so-called "formula"?

Very few, right?

Many people only know that there is such a formula, and a certain straight line can be calculated by using such a formula, but behind this simple formula, there are actually countless formulas hidden, and all the formulas are fully deduced. It's finished.

You don't even need to memorize the so-called formulas, you just need to deduce, and you can naturally get the final correct result in the end.

And...teaching a man how to fish is worse than teaching him how to fish. What's the use of just knowing a formula?The process of memorizing formulas is extremely painful, and you can only memorize them by rote, which will appear boring in the middle, but when you have a kind of thinking in it, everything will become different.

Chen Feng's focus is not on raising the grades of the Nakano sisters to such a high level at this moment. As their friends, Chen Feng hopes that they will have better academic development in the future.

Teaching a dead thing is not as good as teaching a mind.

According to a formula of the Pythagorean theorem, Chen Feng extended it to the trapezoidal formula, extended to the circle formula for everyone, and finally pushed and pushed, everything returned to '0'.

This is Chen Feng's thinking, and it is also what makes him different from others.

Even Sanjiu, who is the least interested in mathematics, listens very carefully, and even draws on the draft paper Chen Feng prepared for them from time to time, even if she did not deduce Chen Feng's result in the end, Chen Feng can see It turns out that their learning thinking of a kind of science is gradually becoming richer.

According to Chen Feng's words, 'every line in mathematics has its meaning, and behind these meanings are more lines'.

The lecture started at 9 o'clock in the morning, and it was not until two o'clock in the noon that everyone realized that they didn't even eat anything. Originally, Chen Feng wanted to cook a good meal for them, but when he saw Clover and San Jiu looked anxious, and the last few people simply ate some pastries and continued teaching.

There was a little accident in the middle, and Rachel also ran to the living room to listen to Chen Feng's lecture.

Originally, the Nakano sisters thought that they could find a sense of superiority in learning from a child who was younger than themselves and others. Who would have thought that Rui Jier's scientific thinking was even a bit on par with Chen Feng.

She followed Chen Feng's train of thought very easily, and many things that Chen Feng hadn't started to talk about were completely deduced by this child. One by one began to become...competitive?

Some of the things that Chen Feng planned to talk about until tomorrow, unexpectedly got out of a small part by Yotsuba, such as some methods used to calculate linear equations in two variables, Veda's theorem...

The happy Chen Feng even threw the mask aside. It was too uncomfortable to give lectures while wearing a mask, so he began to push the whole Vedic theorem up, and stated and practiced the principle under the watchful eyes of four leaves.

"Thank you Chen Feng, can that..."

"You're welcome, if you still can't, keep learning!"

Although everyone said that they didn't understand many things, they were full of interest in this unknown thing, and a sense of panic gradually rose in their hearts.

So I can't even do such a simple thing?what is this?How to do this?Haven't seen this before, check it out...

For a while, the living room of Chen Feng's house was full of a learning atmosphere. Everyone did not fish and chat, nor did they play with their mobile phones in a daze. They were discussing the various conclusions they had drawn seriously, and finally thought that they Ask Chen Feng at the right time, and Chen Feng pours cold water on him.

They have a sense of tension in learning, a sense of fear of ignorance and their previous arrogance.

Chen Feng, who saw all this in his eyes, was even more convinced that the five sisters were not unsuitable for studying, but they were just unwilling to study for some reason.

What surprised Chen Feng even more was Ruijier's IQ, this child's IQ may be much higher than the average person...

She has even started to deduce her high school calculus knowledge...

Rui Jier, who joined halfway, was more like a big fire in this teaching. The Nakano sisters also felt that it would be embarrassing if they couldn’t even compare with a child who was two or three years younger than themselves. Learning has also become more diligent.

So until the end, Chen Feng's mustard and chili water were of no use at all. Instead, he ran here and there to give knowledge to the few people who needed help and raised their hands for help. He almost died of exhaustion.

But this tired Chen Feng is very comfortable!

He is very happy that these people have such an interest in learning. Although what they have learned and their understanding of many things are still relatively superficial in the entire subject, his goal has been achieved, and he only needs to induce A few people pour a bucket of oil on their enthusiasm, and they will naturally think and learn by themselves in the future.

When you are obsessed with something, time flies very quickly, and the sky outside is already dark in the blink of an eye, which completely exceeds the get out of class time set by Chen Feng.

As for the progress of the teaching... I even unknowingly talked about the original content three days later.

Chen Feng gave everyone a little test. Except that Sanjiu had a little problem because she was not good at expressing when deducing and explaining, the results she calculated and deduced completely exceeded Chen Feng's expectations.

The same is true for the others. Their understanding of the entire mathematics subject in one day has completely exceeded Chen Feng's expectations. Perhaps this so-called 'study meeting' or 'training' will end earlier than he expected.

If only they could look at the blackboard instead of themselves.

But Rachel...

Chen Feng looked at Ruijier, feeling a little restless in his heart.

When other people asked him about calculation deduction of geometric figures such as triangles, she had already started to ask Chen Feng about basic function modules; when other people asked him about roots, she had already started to discuss with Chen Feng about learning open and closed surfaces Classification knowledge; when others asked him about geometric determination, she had already deduced a little bit of the prototype of Gaussian formula.

This kid... might be a math genius or something.

"By the way, Chen Feng."

Yihua next to her shouted, her eyes were ready to move, and she approached Chen Feng with a smile.

I really don't know what this girl with a strong mind will say...

ps: Then two pictures!

Chapter 25 Why are there so many liars?

Yihua hugged the notebook in her hand, a funny look appeared in her eyes.
