Ankang University has a special teaching method, and the students are geniuses from all walks of life, so there are often things to compete with each other.

To this end, the school has set up a special competition pilot, and students from both sides of the competition can ask the teacher to ask the teacher to ask questions, or they can ask questions through the system.

The link to the live video of the competition will be transmitted to each student's personal account through the school's official website, of course, if the students are not interested in watching it, they can just click on the fork.

At this time, the ring ratio between Yuzu and Xie Fanqing was the highest number of live viewers almost hit this year's high, not only the students and teachers of the South Academy, but also many people from the North Academy also came to join in the fun, and some people even came to watch it at the scene.

This also includes Chang Wangshu, who happened to go back to school and had nothing to do for a while.

……

In a small hall somewhere, Yuyu and Xie Fanqing stood on both sides of the big screen, and it was rare that there were many people in the seats below. The mentors of the players on both sides came over, and many teachers also came to join in the fun, and they became referees.

Everyone wants to see the strength of Yuzu.

After all, many old students who have been in the school for decades have not reached the B level, but Yuzu's little doll is the A level as soon as she enters the school, and she has also entered the core innovation group of the department.

The teacher in charge of the question snapped his fingers: "The old rule, you have three games and two wins in three games." If a player is not satisfied with the result of the match, he can apply for a best-of-five game. ”

After speaking, he motioned for the two of them to sit down, "The game will start immediately, the first question, basic mental arithmetic......"

Because Yuzu has only been enrolled for more than half a year, for the sake of fairness, the two sides purely test their talent for mental arithmetic of numbers.

The rules of the first question are very simple, calculate all the numbers you have seen in the order of addition, subtraction, multiplication and division, and so on, and whoever calculates the result first will win.

As soon as the voice fell, the numbers began to scroll on the big screen, and the numbers flashed very quickly, almost less than 0.3 seconds, and all of them were over seven digits. Or a seven-digit number after the decimal point, the kind where you blink your eyes a little and miss a string of numbers.

The process should last a full ten minutes - after all, we are a mental arithmetic competition, not cross-eyed practice, so every minute, there will be a two-second break.

However, the further back on, the more numbers appear, and there is still a need to solve the square of the root number first, and there is also a symbol interference in between.

On the stage, Yuyu and the two stared intently at the big screen, and the students watching the live broadcast also held their breath nervously, and the barrage was brushed up:

[Although it is basic mental arithmetic, this should be the most difficult difficulty! ] 】

[Not only is it the most difficult, in an international mental arithmetic competition last year, the other party came up with a similar problem, and it took 30 seconds to solve the problem in the first place]

[I'm a little looking forward to who will win between the two]

Because of the inherent impression, most people thought that Xie Fanqing would win, and the people at the scene glanced at the people in the innovation group sitting in the front row, and saw that they all looked calm, as if they didn't care about the game on the stage at all, and they were uncertain for a while.

Ten minutes passed quickly, the big screen dimmed, and the teacher snapped his fingers again: "Okay, now the two sides start answering the questions." ”

When the words fell, Yuyu and Xie Fanqing spoke at the same time: "8546......" plus a decimal point and said more than a dozen digits in a row.

The voices of both fell at the same time.

Not only everyone who watched the live broadcast, but even the teacher who asked the question on the spot was stunned for two seconds, and then came back to his senses and hurriedly clicked on the screen to call up the results calculated by the system.

Shows that the answer is exactly correct.

The teacher who acted as the referee announced the result with a smile: [Xie Fanqing, Jiang Yuyu...... 0.5 seconds, draw]

Yuzu rubbed her somewhat sour eyes, looking ordinary, waiting for the next question.

And Xie Fanqing on the other side was not so calm, he didn't expect that Yuzu could calculate it, and it was as fast as him.

Soon the next question will begin, which is no longer basic mental arithmetic.

"The contestant chooses 90 groups of 9-digit numbers arbitrarily, memorizes the selected numbers, and then finds out the 90 groups of 9-digit numbers from the number series in order, subtracts the 9-digit numbers that have been found, and then writes the answer according to the calculation method given by the teacher......"

The calculation method of this problem is no longer only the basic addition, subtraction, multiplication and division, but also includes the power of the root number of the function equation.

Some of the students in the North Academy began to get dizzy just by hearing the rules.

After a three-second countdown, the race begins. 90 sets of 18-digit numbers appear on the big screen, and the two must pick out 9 digits from each group within three seconds.

Then the big screen turned, and the countdown began again. After three seconds, rows of numbers scroll across the screen, and these sequences scroll through at a speed of 0.3 seconds, and Yuzu and Yuzu need to find the corresponding 9 numbers in these 0.3 seconds: subtract them.

But not every set of arrays can find the corresponding number, if not, the next set until it is found. This is a great test of patience.

There is a stack of paper in front of the two, different from the previous question, this question must be written out of the solution process, after all, the 90 groups of numbers are randomly selected by the contestants, how to verify the answer if you don't write it out?

Some people who have talent in this area also follow the calculation, compared with the first question of basic mental arithmetic, the difficulty of this question is not only to have strong mental arithmetic ability, but also to have a strong memory and keen reflexes, even in special departments, there are not many students who can take care of these points at the same time.

After about two minutes, the number series on the big screen was still rolling, and Xie Fanqing took the lead in picking up the pen.

Until a few more seconds passed, Yuzu was still staring at the screen with wide eyes.

The outcome seems to be clear at a glance, after all, in this kind of genius-level competition, every second is precious.

After another ten seconds, Yuzu finally picked up the pen and lowered her head to brush and write without pause.

This is thanks to the fact that when she first went to the No. 3 building, she often helped Tao Ping'an copy homework. I've trained my writing speed.

This time, the topic was too long, and Yuzu wrote five sheets of paper. Until the answer was finally written, she put down her pen, rubbed her little arm, raised her head and said:

"Teacher, I'm done!"

After speaking, she looked at the audience, but saw many people staring at her in amazement, she blinked her eyes strangely, turned her head, and saw that Xie Fanqing was still writing.

Feeling stared at by her, Xie Fanqing's hand holding the pen trembled violently, and his face turned red. After about ten seconds, Xie Fanqing finally put down the pen.

The answers and calculations of the two were projected on the big screen.

Several referees first checked the 90 sets of numbers, and both of them were completely correct, and then calculated the answers to the questions of the two through the system and manual assistance, which were also completely correct.

In this case, it depends on who can answer the question the fastest.

Start with the pen and work your way up until you put the pen down.

Xie Fanqing took eleven minutes and one second, while Yuyu took ten and twenty seconds.

The referee teacher directly announced, "In the second round, Jiang Yuyu won!" ”

As soon as the words fell, there were bursts of applause from the audience.

Xie Fanqing froze in disbelief, he was conceited and smart since he was a child, everyone praised him as a mathematical genius, for so many years, he had never lost in the comparison among his peers, and he never thought he would lose.

But today, he gave this book to a five-year-old girl!

This reversal was not expected by the students watching the live broadcast, but there was still a martial arts idiot from the North Courtyard who said:

[The two are only 40 seconds apart, and they are almost tied! ] 】

Immediately, a student from the Southern Academy retorted: [Can't you say that, at the beginning, Xie Fanqing's dictation speed was much faster than Jiang Yuyu, which is very normal, after all, Jiang Yuyu is only five years old, and his bones are still developing, and the villain has so much strength, how fast can he write words!] 】

[And Xie Fanqing is already a fourteen-year-old boy, and his arm strength is naturally much stronger than Jiang Yuyu. From that point of view alone, I don't think it's a fair game.

But Jiang Yuyu still won in the end! We can clearly see that when Xie Fanqing writes in the middle, his speed slows down significantly, and there are several stutters in the end. On the other hand, Jiang Yuyu maintains a speed from beginning to end,]

This shows that Yuzu is confident in the answer.

In the luxury lounge, Chang Wangshu stared at the live broadcast screen in the video, and couldn't help but calculate,

However, she was only halfway through the count, and she was forced to interrupt because she had misremembered a few columns of numbers, and she pursed her lips with an ugly face.

Her arithmetic talent is indeed good, but she can't compare with Xie Fanqing at all, let alone Yuyu.

At the scene of the game, it was time for the third round of the key tiebreaker.

The third round of questions is a piece of calculation data during the manufacturing and development of a large ordnance weapon, and for the sake of fairness, the algorithms involved in this set of data intercepted by the teacher are all learned by the two of them.

Both sides must answer the correct answer within three seconds.

The big screen flashed again, almost three seconds later, and Yuzu immediately picked up the brush and wrote down the answer.

And Xie Fanqing on the opposite side took ten seconds to pick up the pen, no matter whether his answer was correct or not, he had already lost this game.

In the applause, the referee announced: "In this competition, Jiang Yuyu wins ......"

Before the words fell, Xie Fanqing stood up suddenly, "Impossible, how could I lose ......"

The referee frowned: "Xie Fanqing, if you are not satisfied with the results of the game, you can apply for another competition!" ”

Xie Fanqing paused, clenched his fists, and turned his head to stare at Yuyu: "I want to compete with you again!" ”

Yuzu shook her head and refused: "Don't, you have to write so many words, it's so tiring!" ”

Xie Fanqing almost thought that she was ridiculing herself, but when she looked down at the little guy, she had a pair of clean and clear eyes, he pursed his lips, and only felt embarrassed that he had never felt before, but he still said:

"I don't need you to write," she grabbed a pen and paper and scribbled a long list of numbers and symbols: "This is a finale question from my big exam last month, and it took me ten minutes to solve it,"

Yuzu picked it up and swept her eyes, and there were immediately students below shouting "It's unfair, bully the little girl......"

Xie Fanqing stared at her closely, his face was ugly and he almost lifted the table and left: "I didn't do that, don't worry, although this question is difficult, the content involved is all ...... you have learned."

However, before the words fell, Yuzu had already put down the paper and raised her head, so she directly said the answer: "82mμm......"

It takes less than a minute,

Xie Fanqing, who was still unconvinced, was like a popped balloon for a moment, and took a step back with a white face, as if the world had collapsed.

He pulled out his secondary card and placed it on the table, then turned around. Striding out with his head down.
