Well?

So fast?

That's a whole grade level.

Lin Qi glanced at the content slightly:

Position & Direction, Division, Statistics, Years, Months, Days, Hours, Minutes, Seconds, Multiplication of Two Digits, Introduction to Geometry and Geometry, Fractions, Decimals, Multiples......

When I was in the third grade of elementary school, I was generally able to get close to a perfect score in mathematics.

But you definitely can't do a 5-minute speedrun.

Lin Qi first asked a division question.

"What is 1557÷37?"

By the standards of the third grade of primary school, this question must be beyond the curriculum.

But considering Xiaoqian's quick calculation ability, it is appropriate to come out this way.

"Equal to 42 more than 3..."

Xiao Qian gave the answer instantly.

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

"Isn't it okay to just calculate the decimal place?"

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

Xiaoqian seemed to be in a puzzle.

Lin Qi knew at a glance that she had calculated an infinite loop decimal number.

"There is indeed a phenomenon of loops, which is called infinite loop decimals, well, it seems to be the content of the sixth grade."

Lin Qi explained.

Xiaoqian suddenly realized.

That's 42.081081...... 081 loops indefinitely. ”

Xiaoqian re-gave her own results.

Undoubtedly correct.

"Oral arithmetic infinitely looping decimals?"

"What is this doing, Fighting?"

The barrage instantly couldn't help it.

"New here, calm down, these two brothers and sisters are like this, each person has a calculator in their heads."

"I'm blanched, and I'm fiercely envious."

……

Lin Qi felt that Xiaoqian had really mastered it.

Asked her another question about fractions, and Xiaoqian accurately judged that all fractions can be converted into finite decimal or infinite loop decimals.

This is also a knowledge point in the sixth grade.

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

It never takes more than five seconds to think.

"Awesome!"

"Can you continue, Xiaoqian?"

Lin Qi asked.

"Of course you can, it's so interesting!"

Xiaoqian was eager to try.

"Shhhh It's so cool to watch other people learn math?'

"This live broadcast room is a little demonic."

"Come on, then."

Lin Qi directly put together the content of the fourth, fifth and sixth grades this time.

"If you think you can understand, keep reading, don't hold on if you don't understand, I can give you hints."

"Uh-huh."

After speaking, Xiaoqian began her own research.

Lin Qi gave her a pen and paper very intimately, without disturbing her, Lin Qi took his mobile phone and sent a message to Ryoko.

"Ryoko, are you still there?"

"I'm here, I'm working as a house manager for you~"

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

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

Lin Qi raised his previous doubts.

"No, she's cutting the video on the go."

Su Yueliang briefly told Lin Qi what had just happened.

"Or is she thoughtful, I only care about interacting with the audience, but I didn't expect there to be such a thing as a return gift."

"These things are her forte, and I promise she's very happy with it, you can just broadcast it with peace of mind, and she'll definitely arrange it for you."

Su Yueliang obviously had great confidence in Cheng Xuetong.

"Then I'll give her a call to thank you later, and just ask her if she has any other suggestions."

"Yes."

"Anyway, Sister Xiaoqian is really a bit powerful, you see the speed at which she is turning pages with the mouse now, I can't read the words too clearly, she has already passed."

"Really? I'll take a look at ......

"Brother, I'm done."

Xiao Qian's voice interrupted Lin Qi and Ryoko's chat.

Lin Qi subconsciously looked at the time, hasn't it only been five minutes?

Five minutes of content for one grade, or five minutes for three grades?

Five minutes is just enough to brush up on these knowledge points in front of your eyes, right?

"I'm going, what, I'm done?"

"I just went to the group and posted a few astringent pictures, and my sister finished learning?"

"Astringent picture gkd!"

……

The barrage was also surprised.

"Can you understand them all?"

"Uh-huh."

Xiaoqian is full of confidence.

"Let's talk about how the formula for the area of a circle is derived."

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

"Divide two circles into an infinite number of small fans, and then spread them out and put them together, which can be seen as a parallelogram, with the base being 2πr, the height being r, multiplied together and divided by 2 is the area of a circle, and π multiplied by the square of r."

Xiaoqian spoke the principle very fluently.

There is no doubt, this is a perfect answer.

And this question includes several knowledge points.

It is enough to prove Xiaoqian's mastery.

"How do you find the area of the fan?"

Lin Qi continued to ask.

"Look at it as a part of a circle, and multiply the area of a circle by the proportion of the number of angles in the center of the fan-shaped circle to a circumference of 360 degrees."

Answer with clarity of thought.

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

"Next question."

Lin drew a line on the paper with a pen.

"What is the length of this straight line, Xiaoqian measured it with a ruler."

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

"Brother, straight lines are infinitely long, and only line segments have lengths, so I can't answer this question."

She replied helplessly.

"Poof..."

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

What a smart little girl!

This kind of pit that he himself stepped on several times as a child could be avoided for the first time.

He rubbed Xiaoqian's hair with his hand.

"That's amazing."

Lin Qi did not hesitate to praise himself.

Xiao Qian suddenly smiled.

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

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

This made Lin Qi laugh even louder.

"What kind of little genius phone call is this?"

"Is this really second grade?"

"I'm so sour, my brother and sister have to have one that belongs to me!"

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

The barrage atmosphere reached a climax in an instant.

"The user "Xiaoqian, come and be my sister" sent a big rocket!"

"The user "Let's start a cram school with my brother" gave away 5 planes!"

The bosses are not skimpy on their gifts.

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

Finally, after examining the knowledge points of equations, Xiaoqian and even the ternary system of equations can see the answer with their eyes.

You must know that Lin Qina's academic modules with 3 points can't help him see the answer directly.

It's true that the modified machine can't beat the prototype!

Now the coffin can be closed, and elementary school mathematics has been completely speeded by Xiaoqian.

The barrage proposed to let Xiaoqian do the primary school Olympiad questions, but Lin Qi refused politely.

For Xiaoqian, who has this talent, building a mathematical framework for her as soon as possible is the most important thing at present.

Math Olympiad questions are nothing more than an extension of "skills".

It doesn't have to be at this point in time.

This leaves only one last foreign language to understand.
