41-20 Mathematical rigging

The carriage progresses with a ragged noise.

This carriage also had a plate spring suspension, just like Lawrence's luggage, and Jen had to be drunk.

The road is gravel-crossed soil. Nevertheless, it was not possible, and the carriage went well.

Only Jen and Kathea are in the carriage. On this occasion, Jen decided to ask Kathea many things.

"I may ask a lot of strange things..."

and to Jen, who had placed it before him, Kathea nodded with a little vigilance.

"The moon is round, isn't it?

"... what?

Kathea stared at Jen with her eyes rounded.

"Have you ever seen a square moon...?

"Huh? Oh, no, it's not... it's fine if you don't"

After all, Jen realized that the moon here is not full.

I haven't been observing it every night, but it's been round for the last half of the month.

Nevertheless, I thought there might even be a month with a full cycle of about a year, and this was the question.

However, it is Jen that Kathea's reaction made it clear that she has never seen such a 'missing' moon.

"Mr. Jin......?

As a kachair, it seemed to be a question of questioning common sense, with no heart or cold eyes to see Jen.

"Hmmm...... is the moon (unique) 'unique'?

"... ha...? The moon (unique) is the moon (unique), right? Is there another way to call me that?

At the earliest, the usual tone hisses and sets the tone when you are concentrating.

"There will be. 'Satellite' or something..."

"A satellite, what is it?

"... from there..."

Jen felt less knowledgeable about the level of tools.

"So I said I might ask you a lot of crazy things,"

"... Sure, I did.... confused memories, are you?

Now Jen was seen with a slightly worrying eye. I feel somewhat sorry for that, but I decide to keep asking questions.

"It changes the story, but how do you remember reading, writing, and calculating?

"In my case,...... my parents taught me to read and write. I'm helping my aunt shop with the calculations, naturally."

"Calculations are additions and deductions, allocations to multiplication?

But also to this question,

"What else is there?

And it was said unto me,

"Square or something..."

"What... is that?

Since Kathea showed a face that seemed a little interested, Jen decided to explain it to her because she was free anyway.

"It's a term used when multiplying the same number by two. If it's two, it's two squares."

"Uh, if so, 3 on 3 is 3 squares, 10 on 10 is 10 squares, okay?

"Yes, yes."

"... and what's the point? 3 on 3, or 10 on 10, then you can't?

"Hmmm......"

Jen got in trouble.

Jen, who is not a math teacher, doesn't know how to explain these questions.

This is all the more so since it is not an explanation of the stage and procedure taken in the first place.

"... a little off the sidewalk, you know what an area is?

"You mean the size of the land, right?

"Well, it's not just land.... So, how do you want the area?

"If it's a long square, it's the horizontal length of the vertical length."

"In that case, if the vertical and horizontal lengths were the same, it could be used for something."

"I know somehow, but I don't interpret it"

"You're in trouble..."

When it comes to numbers, kachairs get mucky.

Jen decided to attack with a change ball.

"So what would be the length of one side of a square with an area of two square meters?

"Uh... uh"

The kachair was eaten.

"If one side is 1, the area is also 1, 2, 4. If 1.5, it's 2.25... if 1.4, it's 1.96... if 1.41. Uh, uh, 1.9881. If 1.42... 2.0164..."

Jen sandwiched her mouth as she wrapped her tongue around Kathea's calculating power.

"Stop.... you know how additions and deductions pair, right?

"Yeah, yeah. Multiplication and allocation will also pair.... The way you put it, there's something paired with squares, right?

Kathea showing sharp insight.

"Exactly. It's called Square Root."

"Heyhokon, is it?

"Yes. I guess it was because squares of aliases are called squares,"

"I see... Square root is helpful when looking for the length of the sides from the area. Is it squares or squares that pair with that?"

That's what I'm talking about.

"It's funny! You know how amazing Jin is."

"Not so much... I think"

"Be modest.... Is there anything else?

After all, Kathea seems to have a predisposition to be interested in mathematical things, Jen decided. Imagine what would happen if you let them learn math properly, etc.

But there's nothing I can do about it now. So Jen asked a question that came to his mind in the math department.

"Do you know how to ask for the area of a circle?

"Is it a circle...... you ask me difficult things. radius to be applied...... oh, applying a three to the radius squares requires more or less area...... does Ms Jin know how to ask for more accuracy?

Jen smiled bitterly.

"No, I don't know if it's accurate, but don't be more accurate when you use 3.14 or 3.14159 instead of 3"

"Is it 3.14159... how many digits does it really have?

"Infinite," they say.

"Infinite!?... How do you know it's infinite? If you're calculating and asking... even if it lasts up to 10,000 digits, you might get Keri at the 11th digit."

After all, Kathea has a mathematically oriented head, and Jen wrapped her tongue around her inside.

"I'm not an expert, so I can't explain that much. By the way, that value is called circumference rate."

"Circumference rate…"

Kathea seemed to feel it.

"I knew Mr. Jin was strange. You don't know what anyone knows, or you know what nobody knows."

"Is it a mess of memories after all?

"I wonder. I don't know."

And he also stared at Jen with glittering eyes,

"Tell me more!

I've said.

After a little thought about what to talk about, Jen laughed heartily, saying that his position was inverted, and decided to do a "three-square theorem" in the flow of the story.

I would also say "Theorem of Pitagoras," but I don't think the name of "Pitagoras" is known in this world, so I decided to go with "Theorem of the Three Squares".

"There's a three-square theorem."

"Is that a three-square theorem?

"Yeah. Uh, you know what a right angle is?

"Yes. It's 90 degrees, right?"

Jen knows that in his former world, Ars, the Metric Method and other units have become used in the past in relation to the spread of Mathematics of the Earth by the 'Wise Man (Magus)' Shuki Tsetzi.

Has something similar happened in this world in the past? and so on and thought slightly in the corner of his head.

But outside the carriage, one of the escorts was listening to these conversations.
