But how can a problem that has plagued the mathematics community for more than 20 years be calculated so quickly?
Just when Yunyan felt that his days were getting more fulfilling, the first high school ushered in the final exam.
The weather was getting colder and colder, and Father Fang made a special trip to take his grandparents home.
Grandpa Fang was originally unhappy and wanted to guard his fish pond and grapefruit tree.
Fang's father said, "Yunyan wants to eat pickled fish, but the fish chosen by our chef does not suit her appetite."
Grandpa Fang and Grandma Fang packed their luggage immediately.
"Let's go and cook for my granddaughter."
Father Fang: "..." I've never been so persuasive before.
Three days before the final exam.
Grandpa and Grandma Fang came from their hometown and changed the way every day to prepare delicious food for Yunyan and Fang Zheng.
And Yunyan is still addicted to this algorithm.
As long as I have time, I will read the literature sent to me by Teacher Zhang repeatedly.
Even when sitting on the sofa to rest, the fingers will draw a little on the armrest.
Once the logical derivation is turned on, it cannot be stopped at all.
It's just that this time she no longer outlines those knowledge points she doesn't understand, waiting for the teacher to answer.
Instead, search for other sources, literature, or reports yourself, and try to understand these things yourself.
To this end, Yunyan has been in the CNKI package for a month.
Also to be able to find more literature.
Fang Zheng saw that his sister was studying so seriously, and he was also stimulated. Recently, he has less time to play games.
When got home, started to brush the queen queen.
Cheng Li opened steam, and saw that Brother Zheng's game time in the past two weeks was only in the single digits in the friend slot.
The whole person's hand holding the mouse is shaking.
He took a picture to Wu Su and sent it over: "Brother, take a look at Brother Zheng's game time, do you panic?"
Wu Su also trembled at the top of his heart, "Damn, is he really a prodigal son, is he hardworking and eager to learn?"
Fang Zheng has always had good grades, and their brothers all know about it.
In a school that takes 70 or 80 Tsinghua University and Peking University exams every year, Fang Zheng's grade ranking is stable at around 200.
As long as the college entrance examination does not perform abnormally, the better 985 will not run.
In this regard, they just feel normal.
There is envy, but no pressure.
Because Fang Zheng is like them, he just plays games when he gets home, and he will finish his math and physics homework.
All other homework is read and copied in the morning.
But since Yunyan returned home, everything has changed.
Fang Zheng has not missed any homework since the end of September. He even completed the excerpts of ancient poems in Chinese and the recitation of texts in English.
The Chinese class representatives were shocked.
After more than a year, Brother Zheng finally handed in an excerpt!
Then, Fang Zheng took over 120 in the mid-term exam in November.
At that time, Cheng Li felt that something was amiss, but Fang Zheng played the same game except for handing in his homework on time.
The pressure on them is still not enough.
It's different now!
Brother Zheng, he doesn't even play games! After class, he was still writing the preface to the Pavilion of King Teng!
When he got home, he was sorting out the wrong questions!
Cheng Li sent Wu Su: "Should we hire a tutor?"
Wu Su: "Okay, my name is Yan Ying, and the three of us will be together."
However, after the three contacted each other, they went to their parents to talk about it.
He got a unified answer: "The three of you study together? Is it right to open the black together? If you really want to learn, I'll ask you a one-on-one tutor. The three of you can't study together."
The parents of the three of them took the exact same script as they negotiated.
Said the same lines.
Three people: "???" Are they so unworthy of being trusted!
Wu Suren was stupid and took this matter to Fang Zheng to cry.
I saw Fang Zheng typed a few lines of words to reply to him—
"Oh, I'm different. I study with my sister, and my parents have nothing to say. Sometimes, they even encourage me to take my sister to play and play games."
"..." Wu Suzu.
Brother Zheng is no longer the Brother Zheng he used to be.
January 7th and 8th is the time for the final exam of the second grade.
The day before the test, Lao Liu announced the time on the podium and said, "After the test, it's everyone's winter vacation time."
The whole class cheers.
"Wow! It's a holiday!"
"It's winter vacation, I want to go to the north to see the snow!"
Old Liu was a little confused and insisted: "Then, the make-up time during the winter vacation is from the 9th to the 17th."
The whole class: "???"
Lao Liu continued, "You must not arrange your travel time during the winter vacation during the make-up class time."
Cheng Lipi smiled and said, "That is to say, the winter vacation starts on the 18th."
"Yes, it made me excited for nothing."
At times like this, there are always demon masters who come out and say, "Fortunately, there are make-up classes, or else I'll have to sign up for classes again."
Lao Liu looked at everyone with a smile on the podium.
"I wish you all good grades in the exam tomorrow and have a good year."
"..."
"I feel that Lao Liu is poisoning us."
"Don't say it, I feel the same way."
Last time, the Yunyan exam was in the last exam room.
Yuan Mo invigilated the whole process.
Guangya cannot cheat.
This time, Yunyan was in the first exam room, and my brother was in the fourth exam room.
Different from the noisy sound of the last exam room that could be heard before walking to the door, the first exam room was quiet.
When Yunyan entered, she couldn't help but lighten her footsteps, always feeling that this was a study room.
