Class 30.
After Wei Minghai finished the question, everyone in the class went about their own business.
That question was no longer of any value to them.
Even He Ruohua understood.
Wei Minghai returned to his seat. Just as he sat down, his deskmate came over." Minghai, I have an app. Do you want to try it?"”
Wei Minghai was speechless.
"Something related to mathematics!"
Wei Minghai grinned." Then I'm excited."”
This app called Gold Medal Mathematics made Wei Minghai's eyes light up.
His deskmate added," It's said that this was recommended by the National Mathematical Olympiad Association and the Education Bureau!”
"There are all kinds of Mathematical Olympiad questions!”
"There's a leaderboard for answering questions!"
"There is a ranking for consecutive answers!"
"Overall correct answer rate ranking!"
"Comparing the total number of answers and the total time taken to answer the questions to the leaderboard!”
"Currently, there are only these three rankings!"
"Although there is an ID, you still have to input the exact name, ID number, and school.”
"With VR mode, as long as the camera is turned on, it's time to answer the questions. If you answer the questions on the paper, the system will automatically record them.”
Wei Minghai registered an account with the ID of Wei (Teacher Xu's student).
Without any preparation, he began to answer the questions.
The deskmate was stunned." Wait, wait! Wei Minghai, aren't you going to read the guide?”
"You should at least go to the forum!”
"This app only became popular this month, and it has already attracted the attention of eight million students!”
"According to the feedback from the forum, the probability of eight million people answering the same question is almost zero!”
"This question bank is huge!"
"Someone has done some calculations. To get the same question, the probability is at least one in five million! One in five million! Hiss…this is too terrifying!"
"And the most basic questions here are the college entrance examination questions, the Mathematical Olympiad questions, and even the university entrance examination questions!”
"Wei Minghai, don't give yourself too much pressure…"
His deskmate had good intentions, but Wei Minghai was so focused on the question that he blocked him.
[Question 1: Prove that the product of four consecutive natural numbers plus the arithmetic square root of 1 is still a natural number.]
Without hesitation, Wei Minghai opened his VR and wrote:
The product of four consecutive natural numbers can be expressed as n (n 1)(n 2)(n 3)=(n ^2 3n)(n ^2 8n 2)=(n ^2 3n 1)^2 -1.
Therefore, the product of four consecutive natural numbers plus 1 is a complete square number, so the conclusion of this question is valid.
"Ding! Identification result: Correct!"
" Time used: 1 minute 17 seconds!"
"Ranking for this question: 1!"
Without any hesitation, Wei Minghai continued with the next question.
The second question was to find the largest perfect square number. After crossing out the last two digits, there was still a perfect square number.
The third problem was to find five different positive numbers such that they were prime to each other, and the sum of any n (n <5) numbers was a composite number.
The fourth question:
……
It was out of control.
Wei Minghai didn't care about class or class. He didn't even go to the washroom. He was obsessed with the questions on the Golden Mathematics app.
The questions here made him feel like he had returned to the sea.
In the past month, Wei Minghai had been studying hard, especially when it came to mathematics. He felt like he had been stuck more than once!
Especially today, he felt that he was like a dragon trapped in shallow water!
However, the appearance of this app made him feel the absolute charm of mathematics!
Wei Minghai became more and more excited.
All the hair on his body relaxed!
"Awesome!"
"This feels so good!"
Finishing the questions was like flipping through a book!
Swoosh! Swoosh! Swoosh!
Wei Minghai was numb to the continuous first place appearances!
He could answer some questions in seconds after reading them.
Although there were no multiple-choice questions here, he could still give an answer!
At this moment, he was highly focused, like a super machine that was calculating.
The bell rang.
Just as everyone was about to make a scene, the deskmate made a shushing gesture.
Everyone was tactful and immediately stopped.
Pairs of eyes stared at Wei Minghai and asked softly," What is he doing? You look so serious!"
"Is this the most serious state that Teacher Xu mentioned?”
"You don't care about what's going on outside?"
"It's the best state when there's nothing around! It was the perfect state where he could give an answer just by looking at the questions!”
" It's as if I can enter my own spiritual space…"
"Look! Wei Minghai did the questions so quickly! I didn't even finish reading the questions and he already gave me the answer! And it's right!"
"So Teacher Xu didn't lie to us. This state really exists!”
All the students were in awe!
"What kind of app is this? We want to try it too!”
"It feels so good to watch Wei Minghai do the questions! Swoosh swoosh, they're all first!"
They were envious!
However, there was still a gap between them and Wei Minghai.
After they tried it themselves, they scratched their ears and cheeks, their faces flushed red.
"D * mn, that's too difficult! I don't know the first question!"
"I managed to solve my first question, but I only beat 20% of the people! He didn't even make it into the top 10,000!"
"F * ck, f * ck, f * ck! How did Wei Minghai do it!”
Just as the students were shocked.
"Ding!"
