That is true for some \(x\) but not others.
We say things like “\(x/2\) is an integer”.We also have similar things elsewhere in mathematics.Some are going to the store, and some are not. The problem was that we couldn't decide if it was true or false, because the sentence didn't specify who “that guy” is.We had a problem before with the truth of “That guy is going to the store.”.
