"I don't get up to a ton of escapades."

"I didn't think so but it still merited saying. Of course I am also available for assistance with non-escapade endeavors."

"Adventures? Capers? Larks? Shenanigans? Sprees? Hijinks?"

"All of those, and also completely mundane activities like helping with homework."

"I'm usually good on homework -"

"I'm not! Help me with my homework!"

"Alright, what do you need help with?"

"Math and Spanish!"

"...I don't actually speak Spanish but I can help you with math."

"Curses. Well, half a loaf." He runs for his math homework.

Katarzyna is extremely math and has experience explaining things to people who are not from helping her sister study!

Xander's experience with math appears to amount to "why can't I hold all these limes".

Well, with math, when you're having a hard time carrying all of the limes, you can put some down by writing things out extremely stepwise. It feels inefficient, sometimes, but it works. 

"Is that why they always want you to show your work?"

"I don't know if that's all of it but I'm fairly certain it's part of it."

"Why don't they say it makes it easier instead of talking about how it makes it easier to grade?"

"I don't know the specifics. I can generate hypotheses of varying levels of charitableness if you like."

"I'm not that curious, really, I just start asking why when things are annoying."

"I do that too but I usually want answers."

"Eh, I'd forget 'em." He tries to go through a problem very stepwise and screws it up anyway because of neglecting order of operations.

Katarzyna re-explains order of operations. "Are you someone who finds acronymic mnemonics useful?"

"Nope. I know my very excellent mother did something with pies but I'll be damned if I know what. Does the order of operations one even stand for anything?"

"If you mean does it expand into a phrase instead of just an acronym, I imagine someone somewhere has done so but I'm not aware of it."

"That's even harder then. Pen-dos? Pam-thaz?"

"Pemdas."
