What does it even mean to be right mathematically here? If I invent a mathematical structure where I define elements 1 and 2, an operation + and a relation = that posits that 1+2=2, I can say that mathematically one apple plus two apples equals two apples. Would I be mathematically right or would I be applying a wrong/not-even-wrong/linguistically deceiving /incoherent model to the real world?
