It is indeed a question.

Wang Yufei was sitting upright in front of Guo Xiaoyi's desk with a pen in hand. Underneath was a stack of manuscript paper. Many numbers and formulas were densely written on the manuscript paper. Their precious daughter was sitting beside her, holding her chin in her hands...

When the two of them pushed the door open, Han Qian noticed that Guo Xiaoyi glanced sideways at the two of them, her eyes completely unfocused, and then moved her eyes to the stack of manuscript papers again...

how to say?

I have never seen my girl speak so easily before.

"Well, can I let Aunt Han take a look at the questions you did?" Han Qian couldn't help but ask.

"Okay!" After saying that, Wang Yufei handed over a stack of manuscript paper honestly.

"Don't look at it. Although I can't understand the problem-solving process, the answers should all be correct. And I've been watching, and this guy definitely didn't copy the correct answers at the end." Guo Xiaoyi on the side said in a sleepy tone.

, and then suddenly turned to look at Guo Jianfeng behind Han Qian: "Dad, you won't join forces to tease me, right? This guy is really a primary school student?"

"What is this guy and that guy? From now on, you have to call Wang Yufei brother!" Guo Jianfeng frowned and scolded: "You don't believe what dad said? You should really be allowed to go with me to see how the children in the mountains go to school.

Yes! It is indeed true that your brother dropped out of school for four years because the family had no money. If you don’t believe it, wait until next time I will take you to ask Uncle Liao!"

Guo Xiaoyi ignored Guo Jianfeng's scolding. After listening to the explanation, she held her chin again and looked at Wang Yufei next to her. This guy still had that calm look on his face, very boring!

…

Han Qian looked carefully at the stack of manuscript paper handed over by Wang Yufei. All the questions and problem-solving processes were written on the manuscript paper.

Her first impression was that the child's handwriting was very delicate and neat, and looked very comfortable. The problem was that she couldn't understand it.

On the manuscript paper, there should be the completion process of three major geometry problems. Each problem-solving process should be very detailed, but there are some mathematical symbols that Han Qian feels she has never seen before.

Of course, this cannot be blamed on Han Qian. After all, she is an English teacher in the high school department. There is no shame in not knowing mathematics. After thinking about it, Han Qian simply took out her mobile phone, carefully took a few photos of the manuscript paper, and then

The folded manuscript paper was returned to Wang Yufei.

"Xiaoyi, your brother Yufei has been traveling all day today, so he has to rest early. If you have any math questions that you don't know, you can ask brother Yufei for help tomorrow."

"It's okay, Aunt Han, I'm not tired, and there are only two questions left. I'll teach Xiaoqian to take a rest after finishing it." Wang Yufei shook his head and said.

Just as Han Qian was about to say something, she saw Guo Jianfeng shaking his head implicitly from the corner of his eye. When he finished speaking, he simply changed his words and said: "Okay, Auntie, go and boil the water in the electric water heater first. You can take a shower after you finish solving the problem.

Don’t do it too late!”

"Okay, I got it, you're so nagging, I still want to watch Wang Yufei solve the problem!" Guo Xiaoyi on the side couldn't help but said, she didn't call Wang Yufei by that guy anymore, but she didn't call her brother either. No matter what, it was good after all.

develop.

…

The first time she walked out of the room, Han Qian sent the photo she just took to the math teacher in her grade group via WeChat. Han Qian couldn't understand it, but Han Qian, the grade-level math teacher she taught, was a math teacher in the key class.

He is an experienced teacher. He is also the subject teaching team leader of the school’s mathematics group. He has rich experience and solid theoretical foundation.

A few years ago, the school spent a lot of money to recruit this teacher Han from an internationally renowned school in Mingzhu. There was no other meaning in sending Wang Yufei's questions. Han Qian just wanted to know what this little guy's math level was.

Sample.

I only went to the fourth grade of elementary school. After reading the textbooks for the third year of junior high school for an hour, I started to solve the math problems for the third grade of junior high school. According to the little princess of my family, without copying the answers, I got

The results are probably correct, which... is hard to believe.

Especially senior teachers like Han Qian.

She has seen a lot of young geniuses in her teaching career, but after all, so-called geniuses still need time to learn, understand, and master knowledge. Those who can learn in half a year what ordinary people learn in three years can probably be classified as geniuses.

The procession started. And it only took one hour... That's not a genius, that's a monster.

"This child..." Han Qian looked at Guo Jianfeng. She was not in front of the child, so she didn't need to hide her surprise.

Guo Jianfeng shrugged, with the same puzzled look on his face: "I told you, this kid is quite intelligent and can solve elementary school math problems."

"but……"

"The message just now was sent to Lao Han, right? Let's see what Lao Han said first." Guo Jianfeng interrupted Han Qian.

The atmosphere between the couple who sat on the sofa again was a bit weird until a message came from Han Qian's cell phone.

"Teacher Han? What's going on? Have you enrolled Xiaoyi in the Mathematical Olympiad class? Have you started learning calculus?"

"calculus?"

"Yes, both solutions to the first solid geometry question are correct. The first solution uses elementary mathematics knowledge, which is needless to say, but the second solution uses the basic knowledge and basic knowledge of calculus in advanced mathematics.

The most valuable thing about the solution is that the derivation process of the calculus formula is also listed in detail during the problem solving process. Xiaoyi has learned well. This means that she fully understands this knowledge! Which study class are you enrolled in?

?I remember Xiaoyi has always been weak in mathematics before, right?"

Han Qian was looking at her phone in a daze when another message was sent.

"Hey, the third question actually uses the problem-solving idea of ​​a complex variable function. What kind of tutoring class is this? Teaching children such a profound thing? This is a difficult point to master even in advanced mathematics taught in universities! etc.

Wait, these questions can't be done by your family Xiaoyi, right? Are you hiring a tutor for your child to test his level? "

"Teacher Han, if I tell you that these problem-solving ideas I posted were not written by my Xiaoyi, but were solved by a fourth-grade primary school student after reading Xiaoyi's junior high school textbook for an hour, you would believe it.

What? You’re not joking, I’m very serious.”

There was no reply on WeChat for a long time. About two minutes later, Han Qian, who had always been very old-fashioned and serious in her impression, unexpectedly posted a very popular emoticon on the Internet. The picture showed a panda head with a confused expression.

Big words: "Are you kidding me?"

Han Qian was stunned for a moment and did not reply to the message. Instead, she threw her phone to Guo Jianfeng, who was frowning and thinking hard.

Glancing at the WeChat chat history, Guo Jianfeng suddenly said: "This kid... I'm afraid he is really a genius who was almost buried?!"
Chapter completed!
