Xiaoyu nestled to the side, and I sat next to her.

Xiaoyu glanced at me and said, "What are you doing here, watching jokes?"

I smiled wryly and said, "What's the matter?"

"No, I'm angry. Xiaoyu turned her head and walked in the direction where she couldn't see me.

"Look, aren't you angry?" I said with a wry smile.

"You're cheating, it's not like you've won me. We said okay to look at the chopsticks thrown into the sky, why do you look at the jar. Xiaoyu said angrily.

Seeing that this must be angry, I lowered my head helplessly and said, "Yes, I cheated because I was not as good as you." How can I know how many chopsticks there are when I throw them so much, I'm just clever. Then you're so powerful, can you teach me?"

After saying that, I smiled bitterly, I didn't expect that I still had this kind of flattery ability. No, no, no, it should be said that you can be so shameless when coaxing children.

"You admit that you cheated, right, you don't win. So you tell me I'm sorry first, I'm thinking about whether to forgive you. Xiaoyu said.

"Okay, well, I shouldn't have won you with my cleverness. Mine is crooked, not to win you. It's all my fault, can you please forgive me?" I said solemnly, but with a smile on my face.

Fortunately, Xiaoyu turned her head and didn't look at me, otherwise you could know at a glance how perfunctory I was.

Xiaoyu slowly turned her head, and I immediately covered my mouth with my hand. forcibly pulled the whole smiling face down, and pulled it into a bitter gourd face to look at Xiaoyu.

"Then I'll forgive you first, teach you to see my mood. By the way, he really wants you to teach me math?" Xiaoyu said.

"He's? oh, oh, it's the dean. He asked me to see you complete Euler's formula today and let you move freely. I said.

Xiaoyu picked up the branch on the side and poked it on the soil on the ground, and I took a closer look at it and it was actually the derivation of the formula.

I immediately took out my phone and Baidu the Euler formula.

When I studied marketing, I just loved math back then. And these formulas know me, I don't know them.

Look at the dense formulas, and the answers found on the phone screen. Almost perfectly, which surprised and delighted me.

The little girl in front of me is indeed a genius, and she is shocked to know how many times more powerful than me.

I really don't know how I'm going to teach her math in the future, but she can teach me whatever she wants now.

She and I are not knowledgeable at all, and I guess only the dean can teach her something useful.

I thought about leaving here after this month, since the volunteers still had money to get this month. I'll be a little sparring partner in peace, because the most important thing is the reporter who comes in 20 days. What I have to do is to leave a good image so that I can get credits safely through the school's assessment. Make up for your credits, so that you can play the last semester in your senior year and graduate with peace of mind.

That's why I'm here, and I can't change my purpose for anything else.

Xiaoyu tugged at the corner of my clothes and said, "I'm done." ”

I took my phone and compared it, and all the four Euler formulas appeared clearly in front of me and the phone screen.

"That's right. I said.

"Needless to say, you've completed your mission today, can you lend me your phone?" Xiaoyu said.

"What do you want your phone for?" I said, puzzled.

"I'm going to teach myself math, and he asked me to hold his phone and teach myself. Xiaoyu said.

I handed the phone to Xiaoyu and said puzzledly, "He, does he mean the dean, doesn't the dean teach you math?"

I thought, it seems that Xiaoyu is also very bad at politeness. Of course, raised by people who are not related by blood. It's that I don't know what to call each other, and it seems that only he is the most suitable.

"At first, he did, but then he didn't know as much as I did. I'm self-taught, otherwise can you really teach me?" Xiaoyu said and actually opened the software, downloaded the vpn plug-in, and logged on Google to look up something on Kivipedia.

Sophisticated, as if he had been learning this way all along.

"Why do you want to go over the wall?" I said.

"Almost all courseware, papers, and videos in China are charged, but it is different abroad. Xiaoyu said flatly.

I watched Xiaoyu on the sidelines using my phone, seemingly looking at trigonometric functions.

The all-English literature was flipped down little by little, and Xiaoyu's eyes were always staring at the mobile phone screen without moving.

The light rain in front of me is a little different than I can understand, originally I thought that what Xiao Yu learned was what the dean himself thought Xiao Yu liked.

Then the mathematics that Xiaoyu learned was the result of the dean's cramming education, but I didn't expect that what Xiaoyu is learning now is really learning out of a hobby. This made me stunned as I watched from the sidelines, and stared at the small rain in front of me.

I've been waiting for a long time, and I'm really bored. But I found that Xiaoyu was still looking at her phone intently, so I thought about it and touched her and said, "Will it affect you if I talk to you?"

"Yes, but I will allow you to ask me three questions. Just let me forgive you for your performance, you ask. Xiaoyu said slowly.

"Math is what you love, that's why you learned it. I said.

"Of course, I go to school. The other kids bullied me because I knew more than they did. They treated me like a freak, so I couldn't go to school. Xiaoyu said.

"And who taught you all this knowledge?" I said, puzzled.

"In the beginning, the doctors, the nurses, and he took turns teaching, and they were able to teach me at first. By the age of nine, I had already memorized all the Chinese characters and taught myself English, French and German. Xiaoyu said.

"Oh my God. I sighed.

"Of course, he taught me math at the time, and I didn't think it was meaningful when I was done. Until that day he found a difficult math problem, and I discovered math. I feel that mathematics is a self-constrained whole, but it is constantly contradictory. What is required is a rigorous calculation process, but most of the time it is inherently ambiguous. Xiaoyu said.

It was the first time I had heard a man explain math in front of me, and this person was a twelve-year-old girl. I thought for a moment and said, "So what do you want to do in the future?" or what do you want to do?"

"All the questions are asked, three questions. I want to be a mathematician, but I'm just learning. I'm going to solve the seven big problems in the future, and I want to make math no longer a secret in people's eyes. Tomorrow I will check all the types and formulas of trigonometric functions, and find me five trigonometric based puzzles. Xiaoyu said.

I gasped to realize what the dean had told me. It seems that the dean learned about it after contacting Xiaoyu, and now I am just taking the dean's place. As for Xiaoyu, as the dean said, she can indeed see a lot of different things in her eyes.

"Hey, why are you stunned. Did you hear what I said? I asked him to do it for me every day, and if you can't, I'll go find him. Xiaoyu said and threw the phone into my arms.

"No, no, no, I can. I said.

Xiaoyu pointed to the distance and said, "After eating, let's go down the mountain." ”

I glanced at the sky and realized that the sun was about to set. I didn't expect to sit in such an afternoon, I picked up my phone only to find that Xiaoyu had completely turned off my phone.

"What? are you going too?" I said, puzzled.

"I'm not going to tell you all three questions. But I'm a good person, and my home is at the foot of the mountain. Xiaoyu said.

"Aren't you from a mental hospital?" I said, puzzled.

"I live in his house down the hill, and I'm not insane. It's a place where I learn, just like elementary school students go to school every day. Xiaoyu pointed to the psychiatric hospital and said.

I nodded.

Xiaoyu got up and patted the dirt on her buttocks, and I learned from her to get up and pat her buttocks.

I had dinner with Xiaoyu, and the doctors and nurses were discussing me in whispers.

It seems that I haven't started to say hello to these doctors and nurses yet, and they have already remembered me.

After that, he and Xiaoyu got on the bus down the mountain, and the driver was still the one during the day.

After going down the mountain with Xiaoyu, she turned into the community on the side.

And I got on a shared bike and went back to school.

For the next 20 days, Xiaoyu used my mobile phone to study on her own every day.

I was only responsible for providing the mobile phone and power bank, and then went back to prepare the questions for her to take back as homework.

The more familiar you are with Xiaoyu, the more worried you are about Xiaoyu's future.

After all, such a little girl who is close to a genius in my eyes can't be buried in a mental hospital for a lifetime, right?

On the 20th, the teacher called me early in the morning.

In a hurry, I picked it up.

"Luqiao, what are you going to do these days? I'll ask a reporter to come to you and interview you about your volunteers. ”

I heard the teacher's phone call, and the mention of the reporter was like an enlightenment.

Thinking about whether I can rely on reporters to publicize Xiaoyu's matter, maybe it will change the status quo.

I hurriedly said, "Today, I'm free today." ”

"Okay, I'll ask the reporter to pick you up at the gate of Xishan. Wait to give you a call, I'm going to see positive news about our school volunteers tomorrow. ”

"Okay, no problem, teacher. I laughed and hung up.

Looking at the text message sent from the phone, a string of completely unfamiliar numbers.

I thought about giving this reporter big news after I finished reporting on the volunteer today.

Get up and wash up and get ready for work right away.
