"You bet I am," he smirked.
"How do you always win?" Keigo whined with a childish pout. You had just won for the 7th time in a row.
"I guess I'm just-"
Knock. Knock. Knock.
"Come in!" you called, Keigo twisting his body so he could see who's at the door since he was sitting so his back faced it.
Shinso opened the door, just awkwardly standing there.
"Oh, hey Hitoshi," you smiled, standing up. "What's up?"
He chuckled awkwardly. "Sorry if I'm interrupting but... I can't understand math."
"Don't worry you're not interrupting, but I didn't understand math either," you chuckled.
"I can help you two," Keigo beamed. "Come on in, lad. You two are in for a math lesson!"

"What do you mean it's the wrong answer!?"
"The calculator says it's wrong! Why do you say it like it's my fault?!" you countered your brother. Turns out, Keigo doesn't know math either.
["What's the problem?"
"Math problem."
"Oh I can help you, let me see."
"Alright, um, here's an easy one. What's 6 times 3?"
*shrug*
"6 times 3?!"
"I don't know."
"6 times 3?!?!"
"I don't-!"
"6 times 3?!?!?!"
"I legit don't know!"
"6 3s!!!"
"I don't know, what is it?!"
"What is it?!" ... "Get your mom."
"Why?"
"Theresa!"
"What's the problem?"
"Homework."
"What's 6 times 3?"
"I don't know."
"6 times 3?!"
"I don't know!"
"What's 6 plus 6?"
"Oh, 12."
"Now add 6!"
"I don't know, what is it?!"
"What is it?!" ... "Get your math teacher."
"Who?"
"Mr. Patrick!"
"Boom! What?!"
"Homework."
"I taught you this! What's 6 times 3!"
"I don't know!"
"Look, if Johnny has 6 times 3 amounts of dish soap, how much dish soap would he have?!"
"How much?!"
"How much?!" ... "1, 2, 3, 4, 5, 6..."]
"Well, in my defense," Keigo argued, "at work, I have people who do the math for me."
"Well lucky you then!" you said exasperatedly. "Hitoshi? Do you know the answer?"
"Maybe," he shrugged, taking the calculator. "Nah, it's wrong too."
You three sighed collectively, staring off into space.
"I'll go ask Momo, she's the smartest," you said, standing up.
"Do it," they nodded.
You closed the door after you, going to find Momo.
"So...," Keigo started. "You're first name basis with my sister?"
Shinso looked up at him. "Well, everyone calls her by her first name so I thought it would be fair."
"Fair enough," Keigo shrugged.
They sat a few minutes until silence until you came back in.
"So?" Keigo asked hopefully.
"She doesn't know," you said, regret in your voice.
"I'll call your math teacher," Keigo decided, whipping out his phone. "It was Ectoplasm, right?"
"Yeah," you nodded.
After a few minutes of silence, Keigo put the phone away, an unreadable expression on his face and looked at you and Shinso. "He forgot to tell you that there's a mistake in that problem. It's unsolvable."
"Why?!" you groaned, falling on your back.
Shinso sighed deeply, burying his face in his hands.
Keigo sighed also, looking off into space as he thought. "So... 'Uno', anyone?"
