My Xueba Life Simulator

Chapter 25 See you late, add a WeChat?
"Find the general solution of the differential equation y''+6y'+13y=0."

This is a differential equation problem, and Ling Cangsong does not believe that Gu Feng can solve it within 10 minutes, let alone answer it in seconds.

Ling Cangsong already felt the dawn of victory beckoning to him, and this question was the touchstone for judging his authenticity as a schoolmaster.

However, the result disappointed Ling Cangsong. Gu Feng was already familiar with this kind of topics that he mastered in his freshman year.

It took Gu Feng only 60 seconds to dictate the correct answer, which was a string of mathematical symbols that the author could not type.

This aroused Ling Cangsong's strong desire to win.

"British mathematician Cayley is the founder of matrix theory. He has such an inference that the product of two matrices can be zero, without requiring one of them to be zero, as long as one of them is indeterminate. This inference is correct. or not?"

"Wrong, both matrices must be indefinite."

"What do we usually refer to as the 'Pearl of the Sea'?"

"Ah, this is simple, it is a Mersenne prime number."

"How many Mersenne primes have been discovered so far?"

"For more than 2300 years, humans have only discovered 51 Mersenne prime numbers."

"British mathematician Shanks, German mathematician Berlehardt, French mathematician Trotta, Indian mathematician Ramanujan, American mathematician Gillis, etc. have all put forward conjectures about Mersenne prime numbers. Their conjectures What has one thing in common, all presented in approximate expressions, and not nearly as close to reality as one would like, is what changes that."

“周氏猜测的出现改变了这一现状，92年《梅森素数分布规律》发表出来之后，让梅森素数变成了一条可以被数学符号表达的公式，即当2^（2^n）＜P＜2^（2^（n+1））时，MP有2^（n+1）－1个是素数。”

"Real variable functions, functional analysis, topology, partial differential equations, differential geometry, algebraic geometry, which one has the most mathematical use value?"

……

Between the two asking and answering, two hours passed.

Ling Xiaoxiao felt that she was a superfluous person, unable to intervene in the communication between the two of them at all.

Gu Feng is more like Ling Cangsong's own son, who perfectly inherited his talent in mathematics.

Compared to the two of them, Ling Xiaoxiao is a scumbag.

She was so shocked that she left the table, and the stable triangle lost a side and became a straight line.

The two endpoints on the straight line are still in constant communication.

The two met each other very late, wishing they could drink and talk happily, and immerse themselves in the ocean of mathematics together without coming out.

Even though Gu Feng didn't brush his teeth or wash his face, he still left a good impression on Ling Cangsong.

Three hours passed, and Ling Cangsong was still not satisfied, as if he was a boy again, he patted Gu Feng on the shoulder.

"You will give Xiaoxiao tuition, I don't worry."

Originally, Ling Cangsong planned to learn from idol dramas and use money to make Gu Feng leave his daughter.

But now, he sincerely hopes that Gu Feng can bring his daughter's mathematics on track.

He believed in the innocence of Gu Feng and Ling Xiaoxiao.

A top student in science and engineering doesn't have time to fall in love.

Even if they live together, they don't have time to love each other.

Back then, he had been single for 25 years, and in the end he was wrong and married Ling Xiaoxiao's mother.

"Come on, add a WeChat."

Ling Cangsong offered to add Gu Feng on WeChat, but Gu Feng couldn't refuse.

This is another middle-aged man who wants to add his WeChat since Professor Dong.

Gu Feng added WeChat, "Well, uncle, can I brush my teeth now?"

"Go and brush, brush your teeth, uncle will take you to have a meal."

Ling Cangsong was very happy, today was really ups and downs.

Ling Xiaoxiao left the venue for an hour, had finished washing, and changed into a nice dress. She looked at her father with resentment: "Dad, what about my pocket money?"

"Pocket money? Don't even think about it. When will you be as good as Gu Feng? Ask me for pocket money again."

Comparing Gu Feng with his daughter, Ling Cangsong felt a strong sense of loss again.

He does not favor sons over daughters, but he longs for his unrealized dreams to be realized by his children.

This is what ordinary parents think. At least in Xiaguo, according to incomplete statistics, 70% of parents have had similar thoughts.

Child, when I was young, I did not fulfill my dream for you.

Now, you must inherit my hobbies and fulfill my dreams.

Otherwise, you are not my good boy.

Dad, then who am I?
You picked it up in the trash can...

Gu Feng brushed his teeth and washed his face in one go, went to the bathroom again, and walked out of the bathroom comfortably.

Ling Cangsong answered the phone and looked at Gu Feng apologetically.

"Xiaofeng, I'll invite you to dinner another day. I have to go back because I have something to do with the company."

Gu Feng waved his hand: "It's okay, uncle, go get busy."

Ling Cangsong glanced back at his daughter Ling Xiaoxiao, and said seriously, "Xiaoxiao, explain it in the family group."

"Good dad."

Ling Xiaoxiao personally went downstairs to see her father off, and Gu Feng watched a black Lincoln drift away through the glass window on the balcony on the fifth floor.

"Rich people."

Gu Feng sighed silently, and prepared to go downstairs for breakfast.

He already knew the ins and outs of the matter, so it turned out that there was nothing abnormal at all, it was Ling Xiaoxiao's cousin who made the trouble.

I plan to have dinner, pack my luggage when I come back, and move back to the dormitory.

Not for anything else, but I don't want to meet Ling Xiaoxiao's seven aunts and eight aunts to check the post again.

If everyone in Ling Xiaoxiao's family knew each other, his reputation would be lost.

When Gu Feng walked downstairs, he happened to meet Ling Xiaoxiao, who excitedly held Gu Feng's hand.

"Ah~~~~"

She screamed.

Gu Feng almost thought that the senior sister had taken the wrong medicine, and that his father was so happy to leave?
Unfortunately, an old lady who came downstairs at this time glanced at the two of them with surprised eyes, and muttered, "Is this pregnant? So happy?"

"..."

Both Gu Feng and Ling Xiaoxiao were speechless to the old lady.

Seeing that no one was paying attention to her, the old lady went downstairs on her own, leaning on a cane.

Only Gu Feng and Ling Xiaoxiao were left in the stairwell.

"What's wrong?"

Gu Feng asked.

"Stocks went up, they did go up, just as you expected."

Ling Xiaoxiao said in surprise that she was busy dealing with her father in the morning and didn't have time to look at the stocks. Now that she saw it, she was immediately ecstatic.

He almost hugged Gu Feng and kissed him to express his thanks.

Of course, Ling Xiaoxiao still grasped the standard of getting along with friends, but just shook Gu Feng's hand.

"Student, why don't you be my stock trading consultant in the future?"

"No, stock trading doesn't last long, and I don't understand. At most, I will teach you advanced mathematics, and don't think about other things."

Gu Feng didn't want to bring Ling Xiaoxiao into a pit, stock trading was like gambling, there were winners and losers, and he was not Buffett, so he couldn't help Ling Xiaoxiao every time.

This time, he did it entirely to complete the task arranged by the simulator, and he didn't spend money to buy it.

Gu Feng has never been a person who likes to be opportunistic, and he does not yearn for the life of making troubles in the stock market. You must know that when the stock market falls, many people commit suicide by jumping off the building.

Seeing that Gu Feng insisted, Ling Xiaoxiao stopped persuading him.

This time, Gu Feng has already made her a lot of money.
