Baby daddy's unrestrained life

Ye Feng's face is muddled and forced to pass. Although everyone says that no one is right, it's quite strange!

Something's wrong!

But no one paid attention to Ye Feng.

Over there, President Wu said again, "the first level, Professor Ye, is over. The second level is not so simple. Come on, mathematics department." President Wu waved.

Ma Luan, Dean of the mathematics department, stepped forward and said with a smile: "Professor Ye, this second level is the business of our mathematics department. I'll give you a preventive injection first. Our problem is not as flashy as that of the literature department. This problem is really difficult. If you can't work it out before the auspicious time, we can let you go by sending some red envelopes to our department. "

President Ma's words are clear. Originally, Zhao's name was the first pass. No one really wanted to make it difficult for Ye Feng. He just wanted to be happy and ask for some red envelopes. But who would have thought that when the first pass, Ye Feng had a couplet, and Zhao Huangming, they let Ye Feng pass. Of course, up to now, no one has discovered the secret of the Shanglian.

With this lesson, President Ma said it as soon as he came up.

The guests all laughed.

As we all know, it's a fun show.

However, Ye Feng is just a man who doesn't admit defeat. He always has a good face. Do you want him to be soft when he gets married today?

That's almost impossible!

Last pass let you muddle through for me, this pass you still want to fool me?

It doesn't exist!

Ye Feng rolled his sleeve, "come on, let's go. In mathematics, I'm not afraid yet!"

"Well."

Dean Ma laughed unkindly, "this is what you said, then I'll make a question?"

Ye Feng confidently smiles, "come on, I'll go on."

President Ma said with a smile: "this second level, our mathematics department has only one problem." Ma ran stretched out his hand and said, "excuse me, Professor Ye, how much is the sum of all natural numbers?"

President Ma finished, and the guests on the scene were all muddled.

Sum of all natural numbers?

What the hell is that?

Even if they are not engaged in mathematics, even Mr. Song Qingxuan, who is engaged in calligraphy, knows that there are infinitely many natural numbers. How can these things be summed up?

It's impossible to have and!

A lot of people are confused when they hear this question.

Only a few old mathematics professors from Tsinghua University and Peking University were slightly surprised.

Mr. Ma explained with a smile: "this problem is easy to understand. Natural numbers are 0, 1, 2, 3, 4... How much do you add them together? Professor Ye

"Director Ma, you really don't want Professor Ye to pass the exam," said Jin, director of the sports department with a bitter smile

Hu, Dean of the Chinese Department of Peking University, shook his head and said, "it's obvious that Professor Ye is going to pay for the red envelope. It's impossible to calculate it."

Zhao Huangming raised his thumb to the people in the Department of mathematics, "or you can play, I'm convinced!"

Looking at what everyone said, Dean Ma said: "Professor Ye is the one who has solved the world's top ten mathematical conjectures. This problem may have no clue for others, but it's not difficult for Professor Ye, is it? If you really want to make it difficult for Professor Ye, let's make a guess directly. Isn't it harder than that? "

"Ha, you seem to have a point in saying that."

"I'm convinced to study mathematics."

"He didn't solve the problem, he didn't make sense."

"That's right. Even if you figure it out, what can you do?"

"Yes, the sum of all natural numbers? What's the use of that? "

"Forget it, Professor Ye. You'd better give the red envelope directly."

"This thing can't be calculated!"

Many people have begun to persuade Ye Feng. This problem is obviously that they don't want Ye Feng to pass the test!

Sum of all natural numbers?

It's not a joke, is it!

Even the media outside gave a wry smile.

They have seen a lot of people who make it difficult for the bridegroom to get married. There are people who drink wine, like the first level, people who eat apples, people who hide the bride's shoes, and so on. However, it's the first time for them to see Professor Ye, who is so tall and professional!

On the other side of the rostrum, two hosts are mobilizing the atmosphere of the scene.

The hostess took the microphone and said with a smile: "Professor Ye successfully passed the first level, but now the situation of the second level is not very optimistic. Can Professor Ye still pass it smoothly?"

Male host: "I see hanging, it is estimated that Professor Ye will take out the red envelope."

"Alas, Professor Wang, you are an expert in this field. Help Professor Ye think about it."

"Yes, Lao Li, help Professor Ye to do the calculation."

"This question is too boring. How can it be calculated?"

"Seriously, this problem has been calculated for a long time, but the final value is too large."

"It must be a big number. It's too big!"

"Not to mention the addition of all natures, that is, the addition of infinite 1's and the addition of infinite 100's. These are all the same. The results are all infinite!"

Many people yelled for the help of the mathematics professors at the scene. However, there were so many experts and professors engaged in mathematics at the scene, including Peking University, Tsinghua University, and even the old professors of the Chinese Academy of Sciences. All of them shook their heads at this problem.

In the face of this abnormal and meaningless problem, we are really powerless. Who can figure out the sum of these infinite numbers?

This is obviously an infinite series!

And it's a divergent infinite series!

As we all know, divergent is meaningless!

Let's not say it's the sum of all the natural numbers. Let's just say what the last natural number is. We all don't know. How can this be calculated?

It's impossible to work out!

Looking at them, Dean Ma and the people in the Department of mathematics at Haida all laughed.

They didn't come up with this problem. It was studied by some people in the Western Mathematical circles around the 17th and 18th centuries. However, those mathematicians in this world found that this thing really has no egg meaning. What can they do if they finally study it?

It's no use!

So, in the end, there's no mathematician to do this.

This problem has been neglected in the field of Mathematics for hundreds of years. I didn't expect that it would be taken out to make Ye Feng difficult again today.

However, just at this time, Ye Feng, who had been picking eyebrows and meditating, suddenly laughed. Looking at them, he said with a smile, "is that the only question?"

Ma Luan a Leng, "ah?"

A math professor at Peking University over there was also stunned, "what do you mean?"

Ye Feng chuckled, "are you sure it's this?"

President Ma: "sure, that's it. You can count it!"

The reason why this problem has not been listed in the top ten conjectures is that mathematicians think it is meaningless, but in fact, the difficulty of this problem is no less than that of the ten conjectures. Most mathematicians will flinch when they see this problem. Therefore, seeing Ye Feng's relaxed expression, President Ma felt a little bit nervous, Professor Ye can't really figure it out, can he? After all, he was the man who solved Goldbach's conjecture!

Dean Ma stressed: "Professor Ye, you can't fool us with just one number."

Leaf wind gently oh for a while.

"You have to write down the steps," Ma said

Ye Feng didn't like it again.

President Ma swallowed his saliva, "then you count."
