You’ve inadvertently hit on the beginnings of an apparent paradox to do with the relationship between numbers and the counting numbers
Suppose the largest number you can have is X and the smallest number you can have is -Y. Then between -Y and X, you can count X+Y numbers which is clearly larger than X. But X is the largest possible number so X+Y doesn’t exist.
