You can't win against the laws of logic! That expression "P ∨ ¬P" is a tautology in propositional logic meaning "P or not P" - which is ALWAYS true no matter what P is! It's like saying "either it's raining OR it's not raining" - there's literally no third option! 😱
That panicked Squidward face is every math student realizing they're in a losing battle. Trying to argue against a tautology is like trying to convince someone water isn't wet - you're doomed from the start!
