Eight forty in the morning.

The 8th teaching building of the Department of Engineering, University of Tokyo, the auditorium.

When 61 representative teams from all over the world arrive.

The host bowed to a group of bigwigs of different skin colors on the rostrum, and then announced loudly: "Next, please invite Professor Aksay Venkatsh, the chairman of this io jury, a number theory expert with magical insight, and a winner of the 2018 Fields Medal. He participated in the io at the age of 11 and won two bronze medals in a row, to announce the competition rules for us!"

As an Indian-Australian mathematician, Aksayi Venkatsh, wearing a pair of narrow-framed glasses, always exudes a melancholy temperament that only poets can possess.

When the female student in the mathematics department saw this great god, she immediately couldn't do anything to herself. She was so happy that she almost rushed forward and devoted herself to science!

The great god participated in io at the age of 11 and won a bronze medal. The following year he won another bronze medal. He entered the University of Western Australia to study mathematics and physics at the age of 16. He graduated with an honorary degree at the age of 20. He received a doctorate from Princeton University at the age of 26. He became a tenured professor at Stanford University. At the age of 7, he won the Fields Medal with the Nobel Prize in mathematics for his comprehensive achievements in analytical number theory, topology, representation number theory, etc.

The moment Zhao Zhuo saw Aksai Ventash, he excitedly pinched Shen Tongwen's arm and exclaimed: "I'll go! The Japanese actually invited this person over! This person is my idol! You know..."

But he seemed to have ignored Shen Tongwen's feelings.

Bang!

The next second, Shen Tongwen slapped Zhao Zhuo's dog paws and cursed: "Are you sick? You touch me every time!"

“…!”

Wu Dongyue, Tong Fei, Yan Xingbai and his group heard the sound, and everyone subconsciously looked at the two of them.

The eyes were filled with something indescribable.

"Old Zhao, I didn't expect you to be so good!"

Ouyang Ming glanced at Zhao Zhuo deeply.

Subconsciously, I distanced myself from this "best friend".

"This group of naughty kids!"

Yan Xingbai felt much more at ease when he saw Zhao Zhuo, Shen Tongwen, and Ouyang Ming's relaxed appearance.

Retracting his thoughts, he glared at the three of them and said, "Don't talk nonsense! Listen to me carefully!"

At this time, Aksayi Venkatsh just finished talking about the rules and smiled slightly: "Okay, kids!

Here I will say something off topic. No matter what your final grades are, please don’t give up on mathematics! The beauty of mathematics lies in the fact that it is everywhere! As long as you have a curious heart and a pair of careful eyes, you can discover her amazing beauty!

Fall in love with her unswervingly!

Dedicate everything to her for the rest of my life!

I hope you can remember my words, enter the examination room with awe and curiosity about mathematics, and accept the first obstacle she set for in your life! I hope you can all overcome this obstacle, surpass yourself, and discover a better self!

I firmly believe that the future of mathematics belongs to you!

Come on, teenagers!"

As soon as the words finished, thunderous applause rang out in the lobby. At this moment, whether it was Chinese, Lighthouse, Eagle, German, Indian, or Goryeo who had recently risen in the io field, contestants, team leaders, coaches, and media people who came to witness the io competition all applauded, paying tribute to Professor Aksayi Venkatsch and also paying tribute to mathematics.

Before, perhaps Wu Dongyue would envy Professor Aksayi Venkatsh at this moment. However, the times have changed. Since he experienced the Shenhe-4 incident on the moon, Yan Xingbai discovered his identity and was guided to join the Soul Hunter Association. After truly understanding the earth, he understood what he wanted more!

Truth is certainly what he loves, but now he loves the power-given truth.

When science and superpowers collide together, what kind of sparks will burst out?

Wu Dongyue was very curious about this!

Less gossip.

With Aksay Venkatsh announcing the start of the competition.

61 representative teams around the world rushed into the examination room with generous steps.

The rules of each io are basically the same, with a total of six questions.

Three questions a day, each question is 7 points.

The daily competition time is 45 hours.

Except for pens and drawing tools, no other electronic tools are allowed to be brought into the examination room.

Wu Dongyue got the question and after reading it, he felt relieved: "It's okay! It's within the scope of normal people's abilities!"

Before the competition, he was always worried that I would come up with some problems that would bother mathematicians.

But now it seems that it was purely his delusion.

Question 1: Non-negative integer ordered pairs (,n). If there is no need to carry when finding n (in decimal), it is called "simple". Find the number of simple non-negative integer ordered pairs of 1492?

Solution: Because there is no carry when summing,

Therefore, there are methods to add single digits to 2: 02, 11, 20;

There are 10 ways to add ten to nine;

There are 5 ways to add 100 to 4;

There are two ways to add thousands to 1;

Thus, the total number of simple non-negative integer ordered pairs with sums of 1492 is:

2510=00

Wu Dongyue glanced at him and then took forty seconds to answer the question.

Then start the second question quickly.

This speed is really conspicuous!

Question 2: Find the maximum distance between two points?

One point is on a spherical surface with points (-2,-10,5) as the center of the sphere and 19 radius.

The other point is on a spherical surface with points (12, 8, -16) as the center of the sphere and 87 as the radius.

"I'll go! The teacher who asked this question is really lewd!"

Wu Dongyue glanced at him quickly and recalled the speech that Aksayi Venkatsh compared mathematics to women just now. Suddenly, his thoughts flew. He couldn't help but think of the pair of tall and towering mountains on Song Qinghong's chest, which were now very rounded by him.

Isn’t this question the longest distance between the tops of these two peaks on the same plane?

If you want to require this length, you must use your hands! Oh! It is the distance formula between two points a1(x1,1,z1) and a2(x2,2,z2) in space: |a1a2|=√(x1-x2)2(1-2)2(z1-z2)2.

As long as you find the right formula, this question is a free score.

After calming down, Wu Dongyue took back his thoughts from the white peaks.

He curled his lips and said, "Is this an illusion? Why do I feel that the question of io is not very difficult!"

Solution: Let o and o1 be the centers of the two spheres, p1 and p2 are the intersection points between the extension line of the line segment oo1 and the two spheres, and o is in po1 and o1 is in op1. pp1=pooo1o1p1=19187=17. Then the maximum distance between the two points oo1=1.

With a big stroke, this question took twenty seconds extra because it was distracted.

Next, the third question took a little effort, but it only took three minutes to successfully complete it.

At this point, Wu Dongyue has completed all the competition topics on June 18.

After checking it and confirming that there were no problems, Wu Dongyue decisively chose to hand over the paper.

"Teacher, I want to hand in the paper!"

The next second, the atmosphere in the examination room suddenly stagnated, as if time and space were frozen. Everyone looked at Wu Dongyue in unbelievable eyes. But in a blink of an eye, when everyone saw the appearance of the initiator, ninety-nine percent of them showed contemptuous smiles on their faces.

"The monkey is indeed a monkey!

Such a simple question actually requires a blank paper!

Sure enough, he is worthy of being a lower creature like a chimpanzee!”

"Interesting! This Chinese boy actually handed in a blank paper!"

"Damn china!

If you want to hand in the blank paper, wait a little longer!

Why do we have to be despised?”

...

"A very interesting little guy! Maybe he will surprise us?"

Outside the examination room, Professor Aksayi Venkatsh had been paying attention to Wu Dongyue for a long time. Just when the invigilator didn't know what to do, he stepped into the examination room and asked, "This contestant, are you sure you want to hand in the paper?"

"How did Professor Aksayi Venkatsh come here?"

A little stunned, Wu Dongyue said affirmatively: "I confirm!"

"professor!"

Aksayi Venkatsch signaled the invigilator to take care of everything.

He nodded and said, "Very good! Please hand over the paper!"

Wu Dongyue shrugged, walked up to the podium quickly, and handed over the paper.

As the chairman of the jury of this competition, Professor Aksay Venkatsch had long been familiar with the answers to the questions in the question bank. At this moment, when he got the test paper, he just took a quick scan and confirmed that the answers to Wu Dongyue's three questions were completely correct.

Looking at the process again, he just exclaimed: "Beautiful!"

The next second, the atmosphere in the entire No. 068 exam room fell into stagnation again.

After twenty seconds, everyone woke up from the shock.

I have cursed Wu Dongyue, mocked Wu Dongyue, and despised Wu Dongyue people. At this moment, I only feel that I was being branded on my face with a blazing iron. The tingling pain penetrated into the bone marrow and could eat my heart and lungs!

"f--k! Didn't he hand in the blank paper, but answered it all right?"

"How is this possible? He has done it!"

"og! Is he a devil? It's all right!"

"Yoxi! The Chinese are indeed worthy of being as excellent as our Yamato!"

...
Chapter completed!
