Mental arithmetic skills

Although Jiang Qili has a good number of Olympiads and has won the provincial championship, this is still a huge challenge for him.

Su Yun immediately smiled when he saw the method of the competition, the first class of the third year of high school is worthy of being a top class, and conflicts in other people's classes are solved with fists, but here is a competition to do test papers and solve them with intelligence.

He nodded, indicating that it was fine.

And Lin Qing was more worried, she should know Jiang Qili's strength, she wanted to stop it, but Su Yun stretched out her hand to stop her.

Su Yun gave her a confident smile.

The smile contained a lot, Lin Qing didn't know what, as long as he saw the young man's smile, he felt inexplicably at ease, and seemed to feel that nothing could bother him.

The two were seated far apart, and when the crowd gave the order to start, the two moved.

Jiang Qili does have two brushes, and he doesn't need a draft at all, and he writes very smoothly on the test paper.

On Su Yun's side, he didn't even mean to write, he just flipped the test paper and read it carefully.

"Hahaha, the waste of the sixth class of the third year of high school is the waste, I don't think he can do a single question. ”

"Well, you see, he's dumbfounded, and doesn't know where to start. ”

"Haha, get out of this garbage, we don't accept this kind of garbage in the first class of our senior high school. ”

The movement in the class was very noisy, and even Xu Shirou, the first student in the first class of the third year of high school who didn't care about anything except her grades, couldn't help but look sideways.

She knew Jiang Qili's strength, and she was also curious about Su Yun's true combat power.

The person who can write Goldbach's conjecture is definitely not as simple as it seems.

Although in Xu Shirou's eyes, it is impossible for the other party to argue correctly.

Half of the time had passed, and Jiang Qili had also written half of his Olympiad math question, turned his head to look at Su Yun, and found that the other party had just begun to pick up the pen.

He suddenly sneered, he won this game, in just half an hour, five hundred Olympiad math problems, even the teacher here could not complete it.

Jiang Qili was still concentrating on continuing to write, and after Su Yun started to write, it seemed like a different person, and the tip of the pen almost appeared to write and draw on the test paper.

The answers to the Olympiad were written neatly on the test paper, without any steps, no calculations, and no pauses.

"Hold the grass, it's impossible!"

One person saw Su Yun's speed, and his jaw was almost dislocated in surprise.

"What's impossible, that kid is already doomed, can't he come back to life?"

A girl who liked Jiang Qili walked over and glanced at Su Yun with disdain, but it didn't matter if she glanced at it, her eyes were round, and she could stuff an egg in her mouth.

Lin Qing had been behind Su Yun, watching the speed at which he solved the problem, and smiled softly.

She knew that Su Yun would not lose.

At this moment, it was class time, and the math teacher arrived at the class to find that everyone was surrounding the two.

One is his proud student, Jiang Qili, the one closest to Xu Shirou in mathematics, who has an amazing talent in Olympiad math problems.

There was another one he didn't know, like someone from the outer class.

Seeing that the two of them were struggling to write, they suddenly understood the reason.

This is the atmosphere of the first class of the third year of high school, if any student is not convinced, he will compete to do the test paper, one does not work for two, and only one person will be counted until he loses.

Half of the math teachers in the third year of high school have a very gentle personality and support this atmosphere, but after a glance at the two of them, he knows the result.

Compared with Jiang Qili to do the test paper, or the test paper of the Olympiad questions, the other party has no chance of winning.

As soon as he thought of this, suddenly an exclamation came from Su Yun's side, "Oh my God, it's done." ”

Xu Shirou stepped forward and stared at Su Yun's test paper carefully for a while, and then knew the result of the competition.

Jiang Qili watched everyone surround Su Yun, with doubts, amazements, and disdain.

But no matter what, the other party has already finished the test paper.

Seeing that the time was approaching, he became even more anxious, he couldn't lose, if he lost, he would have to leave the first class of the third year of high school, which was definitely the biggest shame.

However, when people are more anxious, the more mistakes will be made, Jiang Qili is like this, he is in a greenhouse, he has not experienced a big wave, and he has lost the most important calmness at a little wind.

A math Olympiad problem that was very simple for him, but now he has forgotten the method of solving the problem.

He was so anxious that he scratched his ears and cheeks, on the contrary, Su Yun had already finished the test paper and began to close his eyes and recuperate.

Ahh

Finally, a student who was a referee whistled and decided that the hour must have been up.

Jiang Qili angrily smashed the pen and sat down in a chair in a decadent manner.

According to the previous agreement, if you don't finish the test paper, you will lose.

He only had one question that he hadn't finished, and it was the one that was supposed to be simple and could have been solved with his fingers.

However, because I lost my composure and forgot all the steps to solve the problem, I left a blank on the test paper!

At this time, everyone felt a little embarrassed, after all, they were inclined to stand with Jiang Qi, but now it was Su Yun who had won.

Su Yun walked over and saw that Jiang Qili had not finished a question, and he had lost his qualification for the competition, so he said indifferently: "Are you convinced?"

Jiang Qili gritted his teeth and said: "I don't accept it, I didn't lose to you, I just lost to my customized rules." ”

Looking at the stubborn young man, Su Yun shook his head, the other party was still too young and would not admit defeat in anything.

He laughed and said, "Since you don't accept it, then I'll convince you." ”

Su Yun put his test paper in front of him and said, "The rules just now are invalid, I will continue to compete with me when you are qualified, then the next thing will be to see who has the most points in the questions." ”

When Jiang Qili heard this, he immediately felt a little incredulous, this was simply letting him win.

Because the other party didn't start writing until half an hour later, he didn't think that the other party would be able to do it all right in such a short time.

Even on the podium, the best math teacher in the entire No. 1 Middle School couldn't.

Jiang Qili estimated his results, and due to the tight time, he could achieve 90 percent accuracy in doing the questions.

But what he didn't know was that Su Yun had spent half an hour in vain just now, and he was not doing nothing.

Su Yun read all the questions in that half an hour and memorized them by heart, so when he started to write, there was no pause!

Jiang Qili took Su Yun's test paper and was stunned after taking a look.

He said angrily: "Su Yun, why don't you have steps to solve the question in this test paper?"

Su Yun raised his eyelids lightly and asked, "Is it important?"

"You" Jiang Qili said angrily: "You don't have a solution step, who knows if you plagiarized the answer?"

"Who took out the test paper?" Su Yun asked indifferently.

"I ......"

Jiang Qili felt speechless, yes, how could the other party have an answer, this test paper was the one he was most afraid to draw out, it was taken out in his backpack, the other party had no reason to know the answer, there were so many people watching, and it was impossible for the other party to plagiarize.
