Gift?

Did you prepare a gift for me?

Immediately afterwards, Xu Mang saw the legendary gift. This gift was very exquisite, and it could be seen that everyone was paying great attention to it. However, unfortunately, Xu Mang did not want to accept this gift, mainly because it was too laborious.

A carefully crafted applied mathematics problem.

I

Crazy?

Xu Mang was quite angry. It was like he was a child in elementary school. One day it was his birthday and suddenly his uncle came over and gave him a sack of gifts. When he opened them, they were all exercises, ranging from elementary school to high school.

"Professor Xu!"

"This is a carefully crafted gift for you from all the mathematics professors at Columbia University." An old professor said with a smile: "You see, it contains many elements, and we hope you can solve it.

, understand your true strengths in mathematics.”

sorry,

reject!

Xu Mang was about to speak when his cousin suddenly spoke and said seriously to Xu Mang: "Xu Mang, just satisfy them. These people really want to know your talent in mathematics, otherwise they will be depressed to death."

These words were communicated in Chinese.

"oh"

"Then let them be depressed to death." Xu Mang answered simply. Originally, he and Xiaoman came here for a trip, but they were abducted to Columbia University in a daze, and then to the office in a daze, and then they had to complete something else.

topic.

Why?

Tool man?

""

"Xu Mang, I know you are a little angry, but for the sake of my cousin, please satisfy their curiosity. These old professors especially like to discover some rare world-class mathematical geniuses." My cousin said helplessly: "They

Everyone knows that you are my relative, you can’t embarrass your cousin, you must finish it!”

Xu Mang glanced at Xiaoman, saw her nodding to him, and said silently: "For your sake, cousin, I will just satisfy them."

Sudden,

Demonic thoughts invaded Xu Mang's brain, and then he had a very bold idea.

"But what?" asked my cousin.

"without"

"It's nothing." Xu Mang said awkwardly.

The words fell,

After taking a look at the question, according to the prompts given by the system, the exchange value of this question is one, which means there is no pressure.

"Can you give me a quiet environment?" Xu Mang said seriously: "I need a relatively quiet environment without anyone around."

"Can!"

Subsequently,

Xu Mang was the only one left in the huge office. Doing the questions? It was impossible. It was impossible to do the questions. However, some people would ask to do the questions themselves. Xu Mang took out a cigarette and lay on the chair, thinking about the next plan.

at the same time,

outside the door,

A group of people are waiting for the answer inside, including Yang Xiaoman. At this time, she is standing in the corner, holding her mobile phone and browsing Weibo alone to see what the cosmetics appraisers have launched today.

Cosmetics used.

However, Xiaoman did not forget to help her fiancé collect information. She was listening to these professors' evaluations of Xu Mang.

certainly,

At this time, everyone was guessing when Xu Mang would finish.

Some people guessed that it would take an hour, some guessed that it would take half an hour, and some guessed that it would take two hours. These professors basically believed that Xu Mang could solve this problem without any surprises, but there was a dispute over the time.

According to Xiaoman's understanding of Xu Mang, she felt that ten to fifteen minutes at most would be enough to complete all calculation processes.

"Xiaoman?"

"How many children do you want in the future?" Xiaoman's cousin stood next to her and asked curiously.

Faced with this problem,

Yang Xiaoman and Xu Mang had discussed it a long time ago, and even the names had been chosen in advance, but now Xiaoman felt a little regretful. To be honest, Xu Mang alone had put herself through so much trouble, and now she suddenly

Two little devils appeared, one big devil and two little devils

Are you still going to let people live?

"I"

"I'm a little scared." Yang Xiaoman pouted and said with worry on his face: "I'm worried that if my child is like Xu Mang in the future, then I'm doomed. I'm a big bastard who didn't have enough for the whole day, and here comes the result again.

Two little bastards came to make me angry, and I'm worried that I will be angry to death by three people named Xu in the future."

""

for a time,

The cousin was speechless, but she quickly thought of a way and said to her cousin: "Why are there three people named Xu? Can't they be three people named Yang?"

Yang Xiaoman shook his head and said with a serious face: "It doesn't matter whether the one named Xu or the one named Yang is the most important thing. The bastard Xu Mang is the boss. Even if the child's temper is Yang's, I still have to raise it. The two children have the same temper."

How can I stand being so stubborn?"

My cousin was speechless: "It won't work this way, that won't work either, just stop giving birth and just be a DINK."

"no!"

"We have already chosen our names." Yang Xiaoman resolutely refused and said seriously: "It's painful as long as it's painful."

The cousin smiled and said nothing.

after,

Xiaoman talked with her cousin about some interesting things at home. Her plan was to use these interesting things to arouse her cousin's idea of ​​returning home. She had not returned to China for more than ten years and it was time to go back, but her cousin's attitude was very tough.

Even if he is beaten to death, he will not go back.

"Xiaoman"

"Some things are not as simple as you think." My cousin said expressionlessly: "Anyway, don't talk about this matter. No matter how much you try to persuade me, I won't go back."

Xiaoman was quite helpless. Although she didn’t know what happened, she heard that the noise was so loud that her cousin was almost ready to jump off the building. Before that, her cousin went to the United States. She stayed there for more than ten years and from then on she was disconnected from her family.

connect.

"Sister at that time"

at this time,

The door of the office was opened, and Xu Mang walked out. In his surprised and shocked eyes, Xu Mang held Xiao Man's hand and said to his cousin, "Xiao Man and I are leaving first."

The words fell,

He quickly pulled Xiaoman and fled the scene.

"???"

"???"

"???"

What's going on?

Why are you leaving in such a hurry?

Everyone was a little curious about Xu Mang's reaction.

When everyone walked into the office and saw the blank piece of paper, everyone was speechless. Xu Mang did not write an answer, but wrote a paragraph on it.

Hello, after reading this text, you will have to solve four questions. Only by solving these four questions can you get my correct answer. These four questions are placed on the first to fourth floors of the left drawer.

"this"

"Is this a test for us?" An older professor reacted and hurriedly followed the instructions above and got four pieces of white paper. Indeed, there were four questions on them, namely abstract algebra, theory of functions of complex variables, differential geometry and

Topology.

"No!"

"This is not a test, this is Professor Xu's challenge to us!" A middle-aged man smiled and said, "Do you accept it?"

Everyone accepted this challenge and began to solve the difficult problems given by Xu Mang. Under Xu Mang's design, these four questions were moderately difficult. Of course, this was only slightly higher for students, but let these professors go.

Once completed, it is just a matter of time.
