"The whole class please?"
"Does it include drinks, fruit plate, and snacks?"
"Monday to Friday, or weekends? I suggest weekends are better, if you have time, but the price is a little more expensive, are you OK?"
"That... Can you bring your family? Hehe."
"..."
Zou Hao almost cried out of anger.
Listening to the tone of these people, it seems that he will definitely lose!
no!
The tree lives like a skin: "On weekends, food and drink are all included, and family members are not allowed!"
"Oye! You're so handsome, elementary school boy."
Zou Hao was patted on the shoulder with a dazed look on his face.
In a blink of an eye, a sophomore in high school gave him a thumbs up: "Nice job! Our class is short of a bold (stupid) cool (money) little Didi like you."
Zou Hao: "..." You obviously said harsh words, but why do you still feel humble
knock!
"Look, Jiang Fuyue started writing—"
I don't know who shouted, and all eyes turned to the podium.
Yes, Jiang Fuyue started.
On the other side, the cap of Tan Jiaxu's pen hadn't been lifted yet, and he didn't look at the question, his dark eyes were fixed on the whiteboard, as if he was in a daze or in deep thought.
"Haozi, is praise okay? It's all started over there!"
"Shut up! What's the matter with you, making others ambitious? Jia Xu has a habit of letting go for three to five minutes before writing when he encounters a problem. You don't know?"
"Yeah, I haven't seen him do difficult problems for a long time, and I almost forgot."
Zou Hao nodded, and inadvertently glanced at Jiang Fuyue, suddenly he felt bad all over: Damn it! How can she write so fast? !
In just a few minutes, dense numbers and formulas have been spread out on half a whiteboard.
"Damn..." Others also found out.
"Didn't you say this question is difficult?" Then why did she write so fast
"It's very difficult... It has not been proven globally..."
"It's over, it's over."
"I found that she didn't seem to use scratch paper."
"real or fake?"
"If you don't believe me, look, once the formula is written, the numbers will be substituted in, and the answer will be obtained directly."
"It really is… "
The sophomore in the front row suddenly turned his head and looked at them with a smile: "Now do you know how many eyes Lord Ma has?"
"..."
Senior: "Sister Yue never uses scratch paper to do the questions. It is more accurate than the calculation by a calculator at a glance."
"… "Grass!
At this moment, Tan Jiaxu, who was originally in a daze, also started to write.
He was very fast, as if he had already had the steps in his mind, but now he just wrote them down silently.
"Haoko! It's started! It's started!"
Zou Hao secretly said to Nass, and immediately responded with provocative eyes: "Our praise is not bad, it just depends on who can have the last laugh?"
Not only was the senior not annoyed, but he shook his head regretfully, the little brat still lacks social beatings...
Zou Hao: "?" When you quarrel, you quarrel. Why are you shaking your head
Twenty minutes later, Jiang Fuyue put the cap on her pen and said lightly, "I'm fine."
The audience was suffocated.
Tan Jiaxu paused his writing hand, then continued in silence.
Ling Xuan stepped forward, even if he had been prepared, he couldn't help but be surprised.
too fast.
There seems to be no difference between difficulty and difficulty in her eyes, the only difference may be the length of time it takes to solve them.
On her face, it seems that confusion and confusion can never be seen, and she is resolute and brave at all times.
Mount Everest can be measured, but no one knows where Jiang Fuyue's thinking ceiling is.
At that moment, Ling Xuan seemed to see the gap between the two—
Not a chasm, but a moat.
Thinking about her relationship with her father...
Ling Xuan's eyes darkened.
With three minutes left, Tan Jiaxu stopped: "It's fine."
Then it's time to judge right from wrong.
Since this question is a proof question, there is no need to solve it. As long as the process steps can be logically self-consistent and the conclusion can be proved in the end, it can be considered as done.
Ling Xuan: "Now we are all referees. As long as you find any logical loopholes in the steps of the two, then the proof process can be directly judged to be wrong. Twenty minutes, and the timer will start."
Everyone was stunned, stunned—
"Huh? Let's find it?"
"Can I say that I didn't even understand the topic..."
"You are not alone."
"This is a new question. No standard answer can be found on major mathematics websites around the world. This is the only way to do it. Otherwise, is there another better way?"
"Fortunately, this is a proof question. If it is a solution, who the hell knows how many correct answers?"
The wailing sounded continuously, but there were also many people who were calm, such as Ling Xuan.
He has been thinking about this question since he saw it in a magazine two days ago, and he already has a general idea in his mind, so it seems that the steps of the two are effortless.
Another example is Chen Cheng.
The scene in front of me is no stranger to the old members of the Olympiad class.
Because when Jiang Fuyue first entered this class, a similar thing happened, but the person who challenged it was Ling Xuan.
And Chen Cheng was the only one in that "Jiang Ling battle" who stood up and pointed out Ling Xuan's misunderstanding of logic.
Now, history repeated itself, Ling Xuan became the tester and referee, the challenger was replaced by a freshly promoted elementary school student, only Jiang Fuyue was the iron fighter.
Thinking of this, Chen Cheng couldn't help laughing.
Now he is not the boy who blushed when he stood up and said a word.
As soon as the topic was announced, he took out the draft paper below and followed along.
Although it has not been proved to the last step, it is not much worse.
It took him eight minutes to read Jiang Fuyue's proof steps. He had clear thinking and rigorous logic. The whole process was quite smooth and the method was simple.
Then, he read the talk about praise again, but this time it took a full eighteen minutes, and there were a few steps in the middle that he didn't fully understand.
However, the final conclusion is okay.
Based on this alone, he knew in his heart which of the two was higher and which was lower.
Twenty minutes passed in the blink of an eye.
Ling Xuan: "It's time. If you see something, you can stand up and say it."
Everyone looked at each other, but no one stood up.
Ling Xuan changed the question again: "Then do you understand?"
"..." He remained silent, feeling guilty and short of breath.
The real situation is that most people don't even understand the words of the title.
"It turns out that I am not worthy."
"Maybe the Mathematical Olympiad I learned is not the same as sister Yue and the others?"
"I understand Jiang Fuyue's process, but about talking about Jiaxu... I'm a little confused."
"..."
Ling Xuan saw that everyone only dared to mutter in a low voice, but did not dare to stand up and speak, so he had no choice but to turn his attention to Chen Cheng.
This guy is a master of logic. He may not be the best in the class in computing and solving, but he is definitely the most rigorous in logic.
"Okay, then let me talk about it." Chen Cheng stood up slowly while facing everyone's gaze.
"Generally speaking, I can see Jiang's steps at a glance, and they are unimpeded. Although the first part of Tan's approach is different, it is essentially similar to Jiang's method. They are all counter-evidences, and there is not much difference..."
"So you're saying both are right?" Someone couldn't wait to answer.
"That's Sister Yue winning too, more than ten minutes earlier than talking about praise!"
"That's right, it's really hard to fight hand speed with Sister Yue."
"..."
Chen Cheng ignored the surrounding voices and continued: "But the disagreement appeared in the proof of the lemma. In order to prove Lemma 1, Classmate Jiang nested Lemma 2, and discussed and proved it in two cases; while Classmate Tan Using the inequality theorem, trying to prove Lemma 1 to the end, although the final conclusion is correct, but a does not apply to any positive real number. As for why this happens, I’m sorry, I haven’t thought of it yet.”
Ling Xuan nodded, his train of thought was similar to that of Chen Cheng.
Jiang Fuyue is right, there is no doubt about it, because the logical chain is so perfect.
But it's wrong to talk about praise... not necessarily.
Because, which step the problem lies in, they really didn't find it out.
Then just...
"Why don't you take a look at each other?" Ling Xuan suggested to the two.
Jiang Fuyue shrugged: "I don't care."
Tan Jiaxu's mouth tightened slightly: "Yes."
The two exchanged positions.
Five minutes later, without waiting for Jiang Fuyue to pick a mistake, Tan Jiaxu himself said: "I lost."
There was a moment of silence, and then—
"Sister Yue is awesome!"
"What is the undefeated myth, this is it."
"Win, win, win the bet!"
"Primary school brother, big bag for building a dream, the senior will thank you here first!"
"When to go, remember to inform the time in the group~ I'm the group manager, I can help you @全球."
"Also, the fruit plate should be the largest, with cherries."
"..."
Zou Hao: "?"
"Why, do you feel distressed? I would like to bet and admit defeat."
The corners of Zou Hao's mouth turned up, and he pulled out a smile: "I don't feel bad, I don't feel bad at all."
Wallet: I hurt! Weight loss alert!
At this time, Ling Xuan looked at Jiang Fuyue and suggested: "Why don't you tell everyone about your thinking?"
