The answer is 1.
Counting Numbers are numbers that are used to count physical things like books, pencils and teachers. e.g (5 books, 1 pencils, 11 teachers).
They are integers that are positive. They assume that the things being counted are not divisible. So we can have 5 dogs but never 3½ dogs.They are not negative because, when counting things in the real world, the notion of having less than none of them makes no sense
