My Identity As A Schoolmaster Has Been Exposed

After getting the approval of most people, the teacher started the writing process step by step, and finally gave the answer to the question.

These people in the examination group are not just as simple as questioning, they also have to give corresponding reasonable answers.

"From symmetry, we might as well set p(xp, yp) in the first quadrant, then we know from the condition..."

The answer to a fill-in-the-blank question turned out to be the steps of a calculation question in the usual ordinary exam, with as many as six or seven lines.

"BC=√(OB₂+0C₂-20B×OC×cos∠B0C)=√10……”

Soon, he made the answer, and at the same time he raised his head and said to everyone: "Finally got the answer √15!"

When the final answer was written, the teacher who was next to Xu Cong just now was surprised, and hurriedly asked, "Have you ever shown this question to Xu Cong?"

Um???

All eyes are focused!

The scene was still very quiet and harmonious, which suddenly made people nervous.

The teacher looked at him and asked incomprehensibly: "What do you mean? Did Xu Cong find the same problem as me?"

"My question, I just sorted it out and just calculated it, so I shared it on the blackboard!"

When the screaming teacher heard him say this, his whole body got goose bumps, and immediately explained: "No, no! You misunderstood! I was so excited! Because you just wrote this question, Xu Cong is very excited. The answer was given in a short time, and this answer is exactly the same as yours."

The words of this teacher spread to everyone's ears and kept echoing!

"—It's exactly the same..."

"It's exactly the same!

"It's exactly the same!"

In particular, the last four words were lingering in everyone's minds. Everyone looked at Xu Cong in surprise and asked.

"How do you count so fast?!"

"Student Xu Cong, have you seen this question?"

"Impossible! The values ​​here are all set by myself! Even if you have seen it, it is impossible to calculate the correct answer so quickly."

quick?

You are fast!

Real men are strong and durable, and fast people do not have a happy life.

Xu Cong looked at everyone, everyone looked at Xu Cong, the atmosphere became so embarrassing.

"Um... Shouldn't our current priority be to discuss whether this question can be used in the Olympiad test paper?" Xu Cong said weakly.

Then everyone's eyes returned to the blackboard, and the big thing was finished first.

"This question is very good, yes!" "Yeah! I think it's good too!"

"That's it! Put it in the test paper!" "What do you think?"

Everyone passed it. It seems sloppy. In fact, everyone here is very authoritative, and there are very few questions that can be passed by them unanimously.

Soon, the vote is complete!

Huh!

So everyone looked at Xu Cong again, everyone would not forget him, otherwise this question would not be voted so quickly.

Xu Cong was stared at by them so naturally, he was also a little uncomfortable: "Uh...Don't look at me like that!"

Especially the old professors of those famous universities, looking at Xu Cong's eyes even more ardent.

All in shock!

How powerful is this guy in computing!

Although everyone knows this question, it still takes a while to figure out the correct answer!

But Xu Cong was good, answering the question subconsciously, and got the correct answer in a very short time.

They ask themselves, they can't do it! This is not a simple elementary school math problem!

The questions in the Mathematical Olympiad, even the fill-in-the-blank questions, have to go through a series of calculations!

But Xu Cong, this guy directly solved this problem in a short time, this kind of talent is too strong!

"Student Xu Cong, did you really figure it out?" Zhu Tiesen asked aloud with a look of disbelief.

Before he waited for Xu Cong to answer, the teacher next to him excitedly said to Xu Cong: "Yes! What he just whispered must be the answer, I heard it!"

The teacher’s last sentence emphasized the tone, which was obviously to highlight the point.

"Just when the question on the blackboard didn't appear for a while, Xu Cong blurted out and gave the answer!"

Wow...

Everyone looked at each other in an uproar, swallowing saliva constantly.

"Just give the answer?"

"Hi...Student Xu Cong actually has such a computing ability?"

"Unbelievable! Unbelievable! We old men feel like we have been eliminated."

"It is true that the back wave of the Yangtze River pushed the front wave, and the front wave died on the beach!"

...

Seeing a group of old men and some middle-aged greasy uncles talking in frustration, Xu Cong was speechless.

Your focus is not right. Wow! Didn’t you come to publish the paper? Didn’t you come to discuss the topic?

Hey Hey hey!

Don't look at me like that!

All of them look like watching giant pandas!

No matter how thick the skin is, Xu Cong can't stand it anymore. He said to them, "Ahem! You guys, how can I be so good?

He was also afraid that these people would not believe it, so he directly lifted his performance, but it was okay if he didn't pick it up, but when he took it out, everyone was even more surprised!

"Is it so easy?"

"Student Xu Cong, you don't seem to use the problem-solving ideas on the blackboard?"

"Really different!"

Someone's eyes wandered back and forth on Xu Cong's cursive paper and blackboard, and finally determined that the two methods are quite different, and Xu Cong's method is obviously much simpler.

"It's really different! It seems that Xu Cong's simpler answer is the standard answer, maybe it's better, what's your opinion?"

Everyone looked at it carefully, especially the teacher who gave the question. First, he was taken aback for a while, then he directly erased the answering steps on the blackboard and wrote Xu Cong's thoughts.

Xu Cong looked at his operation, is it so impressive? ?

"Um...you don't need to be like this!"

But the teacher who gave the question was not only not angry, but also gave Xu Cong approving eyes, and at the same time he did not hesitate to praise him: "Young people have good brains! This method is good!"

Xu Cong is really a little scared now, and he didn't say anything more, he was afraid that he would say it, and this group of people are looking after him again!

After all, this is really a calculation process written by him subconsciously. If you look for a method seriously, there are even more exciting ideas.

But let's not talk about it...otherwise, if you make a little problem with them, you can't afford to pay for it. They are all top big men in the mathematics world.

After Xu Cong wanted to understand this, he turned his head and looked at these people on his left and right. Each of them had hot eyes, as if they had found a baby.

Xu Cong couldn't help but curled his lips, and muttered in his heart: "I'll still do mental arithmetic in the future... It's better not to say anything!"

It’s better to avoid trouble. In Xu Cong, being over-concerned is already more troublesome. Besides, it is still being taken care of by a group of top mathematics professors in the country!

"You are busy with you! Don't look at me like that!" Xu Cong said helplessly again.
