Question: 1 plus 1 is not 2?
Answer: Just because no one hasn't found a case where 1+1 is not equal to 2 does not mean it is always equal to 2, because it has not been tried infinitely. “1” is an abstract concept. There is no actual physical thing as a 1. I would argue that conceptually if you say that 1+1=2, then yes it is True.
