Adding up a revenge fantasy

When I ask Siri to do advanced math calculations, I think fondly of every math teacher telling me “You won’t always have a calculator.”
Well, I did then, and I do now.
I didn’t always have batteries, but when I got a solar calculator, I didn’t need them.
And then I imagine the math teachers in Hell, having a hundred calculators jammed into every orifice of their body.
Over and over.
Oh, and slide rules, too.
Can’t forget slide rules.
Sodomize those bastards with them.
What about abacuses?
Not as much, I think.
Maybe spank the math teachers with those.
