At this time, Ye Feng was already standing in front of the table, and the pen and ink on the table had been removed and replaced with pens and straw paper. On the top piece of straw paper is written the question that Dean Ma just asked:

What is the sum of all natural numbers?

Ye Feng looked down and picked up the pen.

Many people around came up, especially those professors who were engaged in mathematics, and they stretched their necks one by one to squeeze in, and the reporters behind them even stepped on the stool and held the camera to take pictures.

Dean Ma didn't blink his eyes.

Principal Wu stared with raised eyebrows.

Everyone looked at Ye Feng suspiciously.

At this time, Ye Feng started writing.

Without the slightest hesitation, he wrote a number directly on the papyrus:

﹣1/12。

Negative twelve?

Everyone was stunned.

Why did Ye Feng write this number first?

Does this mean anything special?

Everyone didn't understand, including the math professors of Ma Ran, who were all frowning.

Everyone suppressed the doubts in their hearts, looked at Ye Feng patiently, and waited for his next words to see what he would write next.

However, just when everyone was looking at Ye Feng with blank eyes, this thing directly threw the pen in his hand on the table!

Ye Feng clapped his hands in fear, "Okay, it's over." ”

Principal Wu was stunned.

Dean Ma looked confused.

The surrounding math professors were directly dumbfounded!

Everyone was dumbfounded!

"What's that?"

"That's it?"

"Just a minus twelve?"

"Professor Ye, are you teasing us?"

"What's that called? That's what it's called?"

"No, I'm engaged in literature, but Professor Ye, what do you mean by writing a negative number?"

Dean Ma tugged at the corners of his mouth and said, "Professor Ye, what do you mean?"

Ye Feng chuckled and said, "The answer, the sum of all natural numbers is equal to minus one-twelve." ”

Dean Ma: "......"

Principal Wu: "......"

Everyone: "......"

Everyone looked at the minus twelfth on the paper, and they all felt that Ye Feng was insulting their IQ!

Is the sum of all natural numbers equal to minus twelve?

You're just talking nonsense, and you can also make a reliable number!

Even Principal Wu next to him couldn't stand it, "Professor Ye, don't rely on your identity as an expert to bully us for not knowing mathematics, even if I am from a sports background, I know that natural numbers are positive numbers except zero, and the sum of all natural numbers can be equal to a complex number?"

Director Jin over there also said: "Professor Ye, I am also engaged in sports, so I have to say something fair." Yes, Dean Ma, their question is indeed a bit unauthentic, but your answer is not authentic than theirs!"

Dean Hu of Peking University: "Yes, the final number of positive numbers is a negative number? This, this, this is too nonsense, this is not in line with common sense!"

"That's right, how can he add this thing up to a negative number? And it's a fraction?"

"It's impossible!"

Not to mention other mathematicians, even these historians, writers, calligraphers, and even sports practitioners can't accept it!

What are natural numbers?

It's 0, 1, 2, 3, 4, 5, 6, and so on, which represent the numbers of objects, and these numbers are all positive integers except zero.

Add up all the positive integers and end up with a negative score?

Yes?

Quite the opposite, isn't it?

That thing 1+2 equals 3!

1+2+3+4+……+9999999999…… Did you end up with a negative number? Or is it a fraction?

How is this possible?

It's impossible!

It's impossible!

For this result, no one can accept it!

"Professor Ye, it's a bit unrealistic for you to write a number and just want to fool the past, right?" Dean Ma pouted: "The first level will let you pass in a daze, and you have to talk about this level well." ”

"Hey. ”

Ye Feng said: "The first level is obviously you fooling me." ”

Seriously, Ye Feng still hasn't figured out what the couplet just now is going on.

Zhao Huangming said: "Okay, let's not talk about the couplet, let's talk about this minus twelve, how can this be a negative number?"

Ye Feng said: "Why is it impossible? It's not minus one-twelve, what do you say?"

“……”

Everyone was full of black lines, and they were speechless for a while.

Where do we know where to go!

Ye Feng looked at Dean Ma and asked, "Dean Ma, do you know?"

Ma Chao blackened his face and ignored him.

looked at Zhao Huangming again, "Dean Zhao, do you know?"

"Where do I know where to go!"

"Where's Dean Hu?"

"I don't know ......"

"Director Kim?"

"Director Sun?"

"Principal Wu?"

Ye Feng asked one by one, and they all shook their heads and waved their hands, who knows about this thing!

Seeing that no one knew, Ye Feng smiled, "You don't know the answer, then don't you have it, I said it's minus one-twelve, is there a problem?" Ye Feng spread his hands, "No problem!"

Listening to Ye Feng's words, the corners of everyone's eyes jumped wildly!

Shameless!

It's so shameless!

I've never seen such shamelessness!

Dean Ma's mentality collapsed, "No, Professor Ye, I don't take you to be so cheating!"

"Yes, Professor Ye, you guys are obviously playing tricks!"

"Although we don't know the answer, but we are sure that it will definitely not be this number!"

"That's right, how can it be a score! Professor Ye, don't try to fool us!"

"Professor Ye is cheating!"

"Yes, yes, cheating!"

Everyone rose up and coaxed, Ye Feng was obviously cheating!

This is unbearable!

You must not just let Ye Feng go!

Cheating?

Joke!

When did I Ye someone cheat?

Ye Feng pouted and said, "I'm really not talking nonsense, this question, how much is the sum of all natural numbers, I have calculated it before, it is really equal to minus one-twelve!"

"Huh?"

Everyone was stunned, "Really?"

Everyone looked at Ye Feng and didn't look like he was panicking, they were all a little unbelievable, had they calculated before?

Have you counted all such boring questions?

And the most important thing is that you still have it figured out?

Equal to minus one-twelve?

Although it feels like Ye Feng is not talking nonsense at this time, everyone still can't accept it!

Why do we have negative scores?

It's just this hurdle, and everyone can't get over it!

"If you don't believe it, I can't help it, you can go by yourself when you have time in the future. "Ye Feng didn't mean to give everyone a calculation at all.

At this time, Dean Ma hurriedly said, "Don't, Professor Ye, you can give us a formula." ”

"It's too much trouble, another day. ”

Zhao Huangming raised his eyebrows, "Professor Ye, you don't want to fool us, right? Anyway, if you don't prove how you figured it out, we think you are fooling us." ”

"Hey, am I the kind of person who fools people?"

Everyone nodded.

Ye Feng: "......"

"Isn't it the method of agitation?" Ye Feng said: "Okay! I'll let you understand it today!"

This method of agitation is simply too useful for Ye Feng, after saying this, he rolled up his sleeves and picked up the pen, and wrote on the straw paper with a click.

While writing, he said: "1+2+3+...... Add all the way to infinity, which is obviously an infinite series, and it is also an infinite series of divergence, we all know that divergence is meaningless, the addition of infinite 1s is also infinity, and the addition of infinite 100s is also infinity. ”

Ye Feng said this, everyone nodded unconsciously, indeed, they are all infinite.

However, Ye Feng said again: "Then what is the difference between these two infinity? What is the difference between these infinite elements combined? I have thought about this question a long time ago. "Ye Feng is a serious nonsense now.

He's thought he's been a fart!

The reason why Ye Feng knew this question was because he had dreamed of it!

In the previous life, this problem was also studied, and it was also studied by a famous mathematician named Euler!

The conclusion that the sum of all natural numbers is equal to minus one-twelfth is the result of this thing!

At this time, everyone was stunned for a moment when they listened to Ye Feng's words, including the mathematicians on the scene, and they all frowned.

Ye Feng continued: "Look at this formula. ”

As he spoke, Ye Feng had already written a formula on the straw paper:

There is a limit after 1-2x+3x2+4x3......=1/(1+x)2, which is when the absolute value of X is less than 1, the equation holds.

Looking at this formula, many people can't understand it anymore, only those professors in the mathematics department are still watching carefully.

However, even those math professors are frowning at this time.

However, Ye Feng didn't give them time to think at all, and said to himself: "This formula has a defined domain, and the absolute value of x is less than 1, but we can boldly assume that x=1 will take a look at ......."

"We got a 1/4. ”

"Then, in another formula...... It's a harmonic progression, isn't it?"

"Finally, merge the two formulas ......"

"Isn't this coming out? minus one-twelve!"

Ye Feng didn't write a few formulas in total, and it took less than ten minutes to use it before and after, and then he got this minus twelfth out!

Confused!

This time I was really confused!

What kind of study of literature, what kind of sports, what kind of calligraphy master, what kind of airline leader, what you do, one counts as one!

One is more confused than the other!

Even media reporters are dizzy!

Especially those mathematics professors, they are even more confused than anyone else! Others don't understand at all, but they don't understand what they hear, and they are confused!

The audience was silent!

Everyone looked at Ye Feng in amazement, looking at his minus twelve!

Is this really calculated?

The sum of an infinite number of natural numbers equals a negative fraction?

Yes?

This Nima is not scientific!

Zhao Huangming looked at Ma Chao, "Old Ma, do you understand?"

Dean Ma covered his forehead, "Wait a minute, let me take it slowly." ”

Principal Wu and Director Jin glanced at each other, and both of them swallowed involuntarily.

It's horrible!

Mathematicians are terrible!

Such a boring and unsolvable problem was actually counted alive by Ye Feng?

This Nima is simply poisonous!

At this moment, no one questions it anymore, how can you question this? Professor Ye has written out all the formulas for you, and the steps of the calculation are all there, even if you say that the calculation is wrong, you have to say something four, five, or six, right?

"That's amazing. ”

Dean Hu of Peking University looked stupid, and his hands clapped as if unconscious.

Afterwards, many people applauded with their mouths open.

The applause was not loud, but it reflected the scene more realistically.

It's poisonous!

It's really poisonous!

Ye Feng's hand really scared everyone stupid!

No one expected that Ye Feng would really calculate this impossible problem!
