935 289, Curse's arithmetic class

I don't care who you say you are all of a sudden. This is a public library, right?

"Uh, never mind. I'm leaving now. Come on, keep going.

"Huh! With whose permission are you here!? Outsiders! He'll knock you out!

Well, I guess you're an outsider because you're not wearing a uniform.

"That's why I'm going home. Leave me alone.

"Demon King......"

Is that it? You know me?

"What about you?

"Forgot? It's Sharon de Bazgasica. You saw him in Senior Serge's room, didn't you?

Uh, I remember. Serge, is that your junior?

"Said it was Serge's room!? Sharon! Are you weighing Serge and me!?

"Of course not... this is more proof than anything that I'm here?

Let's go home now. Sounds silly.

"Wait! Are you after Sharon too? Something to give to no one!

"Senior Zagos, that person... is the Demon King, right?

They are all demon kings. I'm not going to say anything like that.

"Become!? Why would the Demon King be in a place like this!? There can't be..."

Do you know just about my existence?

"Don't worry too much. I just kind of wanted to read the book. Study hard, too. That's why I can't beat you, Serge.

Serge, I hear you're keeping the chief. Exactly.

"Ugh, shut up, shut up! I am Zagos of the Viscount Paul family! It would be a low brain where magic is all you can do when you say the enchanted demon king or something! You think you can beat me with your head!

No way this guy... is he the kind of guy who wants to be good cool because he's in front of a woman? Well, you certainly can't win a Mandarin or a social test. I haven't studied. My current education is like a junior high school graduate.

"If it's arithmetic, we can win?

Rather, it can only be won in arithmetic. I don't know what class you're in, but I don't think it's that hard from elementary school.

"Ho? Then you can solve this problem!

What this guy has shown me was the question of seeking the angle of the shape. How much would it cost to add up to all the pentagram's protruding vertices?

"That's a hundred and eighty degrees. Need a commentary?

This is easy. Normally, he learns in middle school, and some students are studying in middle school exam preparation.

Incidentally, even in the Kingdom of Roland, the angle can be three hundred and sixty degrees.

"Become, bullshit! It's decided by chance! Something you can solve by just looking at it without even calculating!

"I want to know. Are you sure you want a description?

"Fair enough. You know the relationship between the inner corner and the outer corner? If you add this inner corner and this inner corner, it's equal to the outer corner here, right? Equally equal here and here. Then, oh wonder. Five corners come together in a single triangle. So a hundred and eighty degrees.

Surprisingly, there will be a lot of middle school students who don't understand this. Even though it's easy.

"Nah, nah! Well, then! Try to solve this too!

"One hundred twenty degrees.

"It's amazing, Demon King! Why the hell does that happen!

"Wait. You, maybe you're not trying to get me to do my homework? I'm leaving now, so do it yourself.

By the way, the problem is, 'The top corner of the triangle aiu is sixty degrees. Draw a straight line that bisects each bottom angle iu, with its intersection as e. Ask for the size of the horn Yew'. You don't know this is horny or horny, do you? Even though it doesn't matter if you don't know.

"That makes it a hundred and twenty degrees. You get it? If you don't know, why don't you just ask your teacher?

I explained it to you when you said you were leaving. Me. You still like people.

"Demon King, it's amazing!

"Gu......"

Whoa, I finally shut up. Goodbye, then. No. Is it the harvest that the arithmetic level of the aristocratic school was known? I guess not. Now I feel like I know again the death of the brave Murasaki and his people, and it's a little blue, isn't it? Still, the royal family contains not only the blood of the brave, but also the blood of Itaya Barbaray. The blood of the rest of us goes on. Right. This is the library, and I looked it up and it's usually on. I'm leaving today, so I'll see you next time. I don't know when I'm coming next.

"Bye. Say hello to Serge.

"Ha!"

Well, I guess I'll go home and have dinner. Let's just say I go to bed early tonight.
