I’m Really Not an Invincible Master

Bai Lin didn't expect that there was still something to learn before the face saint.

This seriously exceeded Bai Lin's expectation, isn't this idle?

Originally, Bai Lin was not happy, and he had to take some courses, and he had to study comprehensively, and he had to take exams in every subject.

This is obviously embarrassing.

So Bai Lin naturally didn't have a good face, just sleeping in class.

What's more, when Bai Lin was in Huaxia in his previous life, he had already slept habitually. Whenever he attended a class, he would be hypnotized by someone. Sleeping was only a matter of minutes.

Bai Lin once secretly recorded Chinese and English classes before graduation, just to prevent insomnia in the future.

But now Bai Lin will face class again.

...

The teacher asked Bai Lin to stand up to answer the question, and the people around couldn't help laughing.

Whispering quietly.

"Dare to sleep in Teacher Li's class, this is a good show!"

"Yes, Teacher Li is famously strict, no one dares to sleep in his class."

"That's right, that's right, I'm afraid this person has never died before."

"Just wait and see."

Everyone cast pitiful gazes, and the picture of Bai Lin being taught a lesson was already imagined in their minds.

Must be interesting.

"Dare to sleep in my class. If you can give me a reasonable reason, I will bypass you today. If you can, don't blame me for being rude."

When Mr. Li was invited by the emperor, his status was very special.

And the status of the students here is not special, so there is also a reason for the emperor to find Teacher Li.

Otherwise, you can't suppress it at all, wouldn't it be a mess.

"Reason?" Bai Lin thought for a while before saying, "If you insist on a reason, then I can only say that what you taught is too simple."

Suddenly everyone roared with laughter.

He teaches mathematics, and strategy in the afternoon. Mathematics is rarely used, so few people learn it, and teachers who teach mathematical mathematics are extremely rare, but Bai Lin actually said it was too simple, he was just joking.

"Are you sure you're not talking nonsense?" Teacher Li thought that Bai Lin had fallen asleep, and opened his mouth to talk nonsense.

These days, no one dares to say that arithmetic is simple. Even the current emperor, who is very talented, when he was young, when he was learning arithmetic, he was always the first and the second.

Never dare to say simple.

Although the person in front of him is good at martial arts, but when he said that mathematics is simple, it makes people laugh out loud.

However, when Bai Lin was in China, he was a university graduate after all, and he learned advanced mathematics. Now these are basically at the infant level. Of course, Bai Lin said it was simple.

"Interesting, it's the first time I've heard someone say that spells are too simple, okay, you can answer the question just now, how many acres is a field ten meters long and eight meters wide?"

"Is this also a problem? One hundred square meters is equal to 0.15 mu, and 80 square meters is equal to 0.12 mu."

Bai Lin's answer didn't stop at all.

Although this is not difficult after all, everyone can do the math, but it takes a certain amount of time to calculate, after all, it involves several steps of calculation, everyone needs paper and pen to calculate for a while to get the answer, but Bai Lin directly calculates with his mind, and a little There was no pause, and it was done in an instant, and everyone present was very surprised.

"this……"

Everyone looked at Bai Lin in surprise.

Although this is just a very simple arithmetic problem, it still requires calculations for ordinary people, and there is no way to complete it in three to five minutes each time.

But when it came to Bai Lin, he just opened his mouth, and he could figure out the answer directly, it was not rude at all, it was as easy as crossing the road in the early morning.

This makes people feel very surprised.

"This... is calculated so quickly?"

"It's done with just heartache? How is that possible?"

"Presumably he should have learned this problem before, so he has already memorized it, so he can calculate it so quickly."

"It must be so. Otherwise, it would be impossible to complete it in such a short period of time if only using mental arithmetic. It is absolutely impossible. If he can, then he is an arithmetic genius."

However, this calculation ability is a very simple arithmetic problem for Bai Lin and perhaps any college student in the new century.

Because after thousands of trials, I still have this bit of mental arithmetic ability, otherwise how would I face the cruel college entrance examination.

But others thought that Bai Lin had done this question before and had already memorized it.

Otherwise, it would not be possible to complete it at all, because they simply cannot accept such mental arithmetic ability.

"A primary school question? Test me? Pediatrics."

Teacher Li was startled, what primary school?

"Okay! Okay!" Teacher Li nodded and continued: "This question is really simple. I will give you another one. Listen carefully. Ask a right-angled triangle. Its two right-angled sides are six meters and eight meters respectively. meters, ask him how many meters the hypotenuse is."

This is the triangle relationship he has researched recently.

Little is known about the whole world, he felt that Bai Lin would definitely not be able to answer.

At the beginning, Bai Lin was still a little flustered. Seeing Wang Jingtao's proud expression, he thought it was some kind of problem, but it turned out to be the Pythagorean theorem.

"It's too simple, the hypotenuse is ten meters." Bai Lin said.

The master next to him was stunned.

"What are they talking about?"

"What right triangle?"

"What right angles and hypotenuses, what are they talking about?"

Everyone couldn't understand what Bai Lin and the others were talking about, because they usually only learned to calculate the number of acres of land, some names for grain, and the conversion ratio between them, and when did they come into contact with triangles.

Seeing Wang Jingtao's surprised expression, Bai Lin smiled calmly and said, "How about it, Teacher Li, am I right?"

Teacher Li was suddenly surprised.

This is something he has only recently learned, and he has not had time to teach it to anyone, even if he teaches it to students, he may not be able to learn it in a while.

However, Mr. Li himself has only a half-knowledge of this knowledge, and only knows a fixed value. As for how to calculate it, he is still researching.

But now, Bai Lin answered it easily, as if he could calculate the answer in an instant.

"You...how did you know?"

"Let me ask you again, is the right-angled side three meters and four meters?" Wang Jingtao asked.

"Five meters." Bai Lin said.

"This..." Wang Jingtao took a step back in fright.

"Isn't he fooled?"

"He really knows how to count?"

Now Teacher Li has confirmed that Bai Lin really knows how to count.

"You...how did you know?"

"This is very simple. I knew it more than ten years ago."

Teacher Li looked at Bai Lin anxiously, and then asked, "How do you calculate this?"

Now he can only know the length of the hypotenuse by measuring, and he seems to feel the rules, but he can't figure out what the rules are.

For this reason, he has not slept much for two days, and this question has been perplexing him in his heart.

The students on the side all looked at each other in blank dismay.

"What else do they say?"

"I do not know!"

"What triangle? What lengths of hypotenuses, lengths of right angles, I have no idea what they're talking about."

...

"You know the truth, how is this calculated?"

Teacher Li looked surprised, but still nodded fiercely. He really wanted to know the reason, otherwise he would not be able to sleep well at night.

"Borrow a pen and paper."

"it's actually really easy."

Bai Lin just randomly drew a triangle on the paper.

Then list the formula.

The square of one side, plus the square of the other side, equals the square of the hypotenuse.

But everyone couldn't understand it.

"what is this?"

"What a mess."

Teacher Li also couldn't understand. He looked at what was written on the paper, and then at Bai Lin.

"What the hell does that mean?"

"Well, the meaning of square is very simple. For example, the square of four is four times four, which is sixteen. Do you understand?"

"So, three times three plus four times four equals five times five, that's the reason."

Teacher Li counted his fingers, from a confused look to suddenly enlightened.

"I get it, I get it!"

"So that's how it is, that's how it is!"

Teacher Li looked excited, and ran out directly: "I finally know the answer, the puzzle is finally solved, haha...haha..."

The students were still in a daze, completely unaware of what they were studying.

It doesn't matter anymore, what shocked them was that it was the teacher teaching the students.

Now it's Bai Lin's turn to teach the teacher!

Finally taught it to the teacher.

"this……"

"Awesome!"

Immediately, everyone gave Bai Lin a thumbs up.
