I can really play with it

Chapter 68 Speed ​​Pass Elementary Mathematics

Ok?
So fast?
This is the content of a whole grade.

Lin Qi glanced at the contents:
Position and direction, division, statistics, year, month, day, hour, minute, second, two-digit multiplication, introduction to geometric figures and solids, introduction to fractions, decimals, multiples...

When I was in the third grade of elementary school, I usually got close to full marks in mathematics.

But definitely not 5 minutes speed pass.

Lin Qixian asked a division question.

"What is 1557÷37?"

According to the standards of the third grade of elementary school, this question must be beyond the outline.

But considering Xiaoqian's quick calculation ability, it is appropriate to do so.

"It's equal to 42 with a remainder of 3..."

Xiaoqian gave the answer instantly.

"But brother, can you not give the remainder..."

"Can't you just calculate the decimal directly?"

"Hey, it doesn't seem right, if you count directly, those numbers will always appear..."

Xiaoqian seemed to be caught in a doubt.

Lin Qi knew at a glance that she had calculated an infinitely repeating decimal.

"There will indeed be a phenomenon of loops. This is called an infinite loop of decimals. Well, it seems to be the content of the sixth grade."

Lin Qi explained.

Xiaoqian suddenly realized.

"That's 42.081081... 081 will loop infinitely."

Xiaoqian gave her results again.

Undoubtedly correct.

"Mouth counting infinite recurring decimals? 』

"What are you doing, fighting? 』

The bullet screen was a little unbearable for a moment.

"You're new here, calm down, these two brothers and sisters are like this, each of them has a calculator in their minds. 』

"I'm so jealous, I'm so envious. 』

……

Lin Qi felt that Xiaoqian had really mastered it.

I asked her another question about fractions, and Xiaoqian accurately judged that all fractions can be converted into finite decimals or infinitely recurring decimals.

This is also the knowledge point of the sixth grade.

Of course, other knowledge points in the third grade are not difficult. Lin Qi asks what Xiaoqian answers.

Never take more than five seconds to think.

"Awesome!"

"Can we continue, Xiaoqian?"

Lin Qi asked.

"Of course, it's so interesting!"

Xiaoqian is eager to try.

"Hiss... so it's such a cool thing to watch other people learn mathematics?" 』

"This live broadcast room is somewhat magical. 』

"Come on then."

Lin Qi directly put together the contents of grades four, five and six this time.

"If you think you can understand it, keep reading. If you don't understand it, don't hold back. I can give you a hint."

"Hmm."

After speaking, Xiaoqian started her own research.

Lin Qi thoughtfully gave her a pen and paper without disturbing her, and sent a message to Liangzi with his mobile phone.

"Ryoko, are you still there? 』

"I'm here, I'm working as your housekeeper~"

Su Yueliang responded to Lin Qi's message in seconds.

"Hitomi seems to be gone, did you go to rest? 』

Lin Qi raised the doubts he had earlier.

"No, she's editing the video just for fun. 』

Su Yueliang briefly told Lin Qi what happened just now.

"She is still thoughtful. I was only concerned with interacting with the audience, and I didn't expect that there would be such a thing as returning a gift. 』

"These things are her strong point, and I guarantee that she will enjoy it very much, you can play it at ease, and she will definitely help you arrange all these things." 』

Su Yueliang obviously has great confidence in Cheng Xuetong.

"Then I'll give her a call to thank her after the broadcast, and just ask her if she has any other suggestions. 』

"Yes you can. 』

"Speaking of which, Sister Xiaoqian is really good. Look at the speed at which she turns pages with the mouse. I can't read the words very clearly. She has already passed. 』

"yes?Let me see……"

"Brother, I'm done."

Xiaoqian's voice interrupted the chat between Lin Qi and Liangzi.

Lin Qi subconsciously looked at the time, hasn't it only been 5 minutes?
The content of one grade is 5 minutes, the content of three grades is still 5 minutes?

5 minutes is only enough to brush up these knowledge points in front of your eyes, right?

"I'm going, what, finished learning? 』

"I just went to the group to post a few pictures of Shibuya, my sister finished learning? 』

"Shittu gkd! 』

……

The barrage was also very surprised.

"Understand everything?"

"Hmm."

Xiaoqian is full of confidence.

"Tell me how the formula for the area of ​​a circle is derived."

Lin Qi did not choose to ask a question this time, but took a question on the level of thinking.

"Divide two circles into countless small fan shapes, and then spread them together, which can be regarded as a parallelogram. The base is 2πr, and the height is r. When multiplied together and divided by 2, the area of ​​a circle is obtained. The value of π multiplied by r square."

Xiaoqian explained the principle very fluently.

Without a doubt, this is the perfect answer.

And this question includes several knowledge points.

It is enough to prove Xiaoqian's mastery.

"How do you find the area of ​​a sector?"

Lin Qi continued to ask.

"Think of it as a part of a circle, and multiply the area of ​​a full circle by the ratio of the angle of the sector's center to 360 degrees of a circle."

Answer clearly.

The knowledge points of "proportion" in the sixth grade are also well mastered.

"Next question."

Lin used the pen to draw a line on the paper.

"What is the length of this straight line, Xiaoqian uses a ruler to measure it."

Xiaoqian tilted her head and looked into Lin Qi's eyes, as if she was analyzing the thoughts in Lin Qi's mind.

"Brother, a straight line is infinitely long, and only line segments have length, so I can't answer your question."

She replied very helplessly.

"puff…"

Lin Qi's serious expression finally couldn't hold back.

What a clever little girl!
This kind of pit that he stepped on several times when he was a child can be avoided for the first time.

He rubbed Xiaoqian's hair with his hands.

"awesome."

Lin Qi was not stingy with his praise.

Xiao Qian suddenly smiled.

"My brother really did it on purpose just now. I said that you are so powerful, how could you make such a low-level mistake."

The little girl had an expression of "Fortunately, I didn't misread you".

This made Lin Qi laugh even louder.

"What kind of live broadcast of a young genius is this! 』

"Is this really the second grade? 』

"I'm so sour, play brother and sister, there must be one that belongs to me!" 』

"Someone wake him up, don't let him taste the sweetness!" 』

The barrage atmosphere reached a climax in an instant.

『The user "Xiaoqian, be my sister" sent out a big rocket! 』

『The user "Let's start a cram school with Wange" sent out 5 planes! 』

The bosses are not stingy with their gifts.

Lin Qi looked at the rest of the content, most of which were related to calculations, and it was really not difficult for Xiaoqian.

Finally, I checked the knowledge points of the equation. Xiaoqian can even see the answer with the eyes of the ternary linear equation.

You must know that Lin Qina's 3-point academic module can't help him see the answer directly.

It really is that the modified machine can't beat the prototype!
Now the conclusion can be drawn, elementary school mathematics was completely mastered by Xiaoqian.

Danmaku proposed to ask Xiaoqian to do the elementary school Mathematical Olympiad, but Lin Qi politely refused.

For Xiaoqian with such a talent, the most important thing is to build a mathematical framework for it as soon as possible.

Mathematical Olympiad questions are just an extension of "skills".

It is not necessary to cut the cornerstone at this point in time.

Then there is only one last foreign language that needs to be understood.
