The mathematical statement "∞ - ∞ = 0" looks perfectly reasonable at first glance. I mean, subtract anything from itself and you get zero, right? WRONG! In mathematics, infinity minus infinity is actually an indeterminate form, not zero! It's like dividing by zero but somehow even more mathematically illegal.
This is why mathematicians wake up in cold sweats at 3 AM. You can't just casually manipulate infinities like they're regular numbers. They're conceptual entities that break normal arithmetic rules. The pirate's "Well yes, but actually no" reaction perfectly captures every math professor's horrified expression when students try this in calculus class.
Next thing you'll tell me is that 0.999... doesn't equal 1. *nervous mathematician laughter*
