At the same moment.

On Weibo, which was quite calm, it was suddenly stirred up by an arithmetic problem!

There is a user who is certified as a teacher of the second elementary school in the capital who posted a question, which is an arithmetic problem in elementary school, "Who can answer it?" Let's give it a try! ”

At the beginning, no one paid attention to it, and when they saw this kind of provocation, they at most subconsciously came in and took a look, thinking that what is so difficult about arithmetic problems in elementary school? We don't have a problem with math problems in middle school, who hasn't been to elementary school, so some people start to answer the questions, but when they seriously analyze the questions and prepare to answer, they find that your mother is not what they imagined at all!

"Damn! Depend on! Depend on! ”

"What kind of arithmetic problem is this?"

"Musical?"

"This is elementary school math?"

"Can anyone tell me what this topic means?"

"Is the answer to the first question 1 multiplied by 3? Isn't that right? Khan, then I don't know. ”

"Are the current elementary school students going against the sky? It's impossible to answer this kind of question! Which teacher lacks virtue from this kind of lack of morality, hey? ”

"Poof, I've given up!"

"Give up together, your head is big!"

Then, I saw that the teacher of the second elementary school spoke again, "Note, this elementary school arithmetic is a question that Professor Zhang Ye, a famous mathematician in the Republic, just came out with today, and by the way, I will hit you again, this question is in the real yàn class of the second grade of our school, dozens of second-grade primary school students also answered, and the correct rate of the children's answers is 93.2 percent, only two people in the class are wrong, and dozens of other people all answered correctly!" ”

Now, the Weibo is lively!

"What? Zhang Ye's question? ”

"Is it really elementary school arithmetic?"

"Since it is Zhang Ye's handwriting, this question is definitely not so simple."

"In other words, a world math master, can he do ordinary elementary school arithmetic problems? There must be layers of mystery inside, I'm interested, watch me unravel it! ”

"More than 90 percent of elementary school students are correct? I don't believe it! I don't even know what that means! Elementary school students can't do it! Even the best students in the real yàn elementary school in the city can't be smarter than adults, right? ”

"Look at me!"

"I'll try it too!"

"I'm sure I can unravel it, I think about it......"

"I don't believe it yet!"

Gradually, netizens' answers are one after another, each more bizarre than the other!

Suddenly, some celebrities also appeared, such as Zhang Ye's friends.

Yao Jiancai posted: "What a problem Xiao Zhang came up with! ”

Peking University teacher Suna: "Angry! Flip the table! I'd better teach my Chinese well, the world of mathematics is terrible. ”

Xiao Lu of Beijing Satellite TV: "Poof, this topic is really funny, Ding Ding Ding?" Ding Ding Ding? But this is really like Mr. Zhang Ye's style! ”

In the end, the teacher of the second elementary school announced the correct answer, not to mention, there are really a few people in the netizens who answered correctly, but the rest of the thousands of people are all wrong or unable to answer, this correct ratio is simply incredible, the children in the real yàn class with a correct rate of more than 90% are all aliens? They are not as good as a group of elementary school students??

"What's going on?"

"What the hell?"

"Is the teacher of the second elementary school talking nonsense?"

"Are all the children nowadays so perverted?"

Netizens said that they couldn't accept it!

At this time, Dean Pan of the School of Mathematical Sciences of Peking University didn't know whether he heard the student tell him or he saw this topic by chance, and he actually left a message on Weibo. It's for you to jump in! ”

When they heard this, they all screamed!

"Huh?"

"Is it to fool us?"

"Zhang Ye is too lacking in morality!"

"This thing has always been this nature!"

"Poof, I know! Mr. Zhang is a pit in itself! A sinkhole! Whoever gets close to him will have to fall in! ”

"What the hell is it?"

"Dean Pan, explain quickly."

Dean Pan said: "The principle of this trap is that the thinking circuit of adults and primary school students is different, adults are easy to complicate simple problems, this complication may have started from the moment of reading the question, this is a mode of thinking that adults are unconscious, but children are different, maybe these notes or onomatopoeia are good, for them it is some fixed special pictures, those onomatopoeia itself may not have much meaning to them, so they can see the essence of the question lightly, Solve the answer, so from a certain point of view, adults may really not be as good as elementary school students in this aspect, so most of the questions they can answer correctly are not answered correctly! ”

"I see!"

"Damn, that's the case!"

"I said it!"

"Zhang Ye is really a grandson!"

"If this guy doesn't cheat people for a day, he will be uncomfortable for a day!"

Everyone condemned it, and they all laughed and scolded Zhang Ye for his lack of morality!

Dean Pan said: "It seems to be an elementary school arithmetic problem, but the philosophy and reflection contained in it are not at the elementary school level. Professor Zhang Ye is worthy of being a genius in the field of mathematics, this topic is very interesting, I have written it down, and I am ready to let the students of the Department of Mathematics of Peking University also come to do it, research and research, some things and some problems, maybe look at it from a different angle to solve, maybe there can be an unexpected result! Professor Zhang told everyone that at any time, don't underestimate any seemingly simple question! Because they may not be as simple as you think, or they may not be as complicated as you think! ”

Yes?

Do arithmetic problems for elementary school students for Peking University students? Still going to study it in depth?

Dean Pan's words are undoubtedly too high for this elementary school arithmetic question, and too high for Zhang Ye!

After listening to Dean Pan's explanation, everyone also understood the trickiness in this question, and then pondered carefully, everyone had to admire Zhang Ye's talent, knowledge and whimsy, a primary school arithmetic problem can also be played with so many tricks, and it is philosophical, mixed with psychology, and the core value of mathematics, and the most important thing is that there is a wide range of uses to slap people in the face, the master who can come up with this kind of strange arithmetic problem, the whole republic is probably only Zhang Ye who can find something to do if he has nothing to do!!
