Zero is not a positive number. Neither is it negative. Rational numbers are an fraction. Eg: 6/10 or 6/6 They can also be whole numbers because 6/6 is also 1.

Why is the set of positive whole numbers closed under subtraction?
The set of positive whole numbers is not closed under subtraction! In order for a set of numbers to be closed under some operation would mean that if you take any two elements of that set and use the operation the resulting "answer" would also be in the original set.26 is a positive whole number.40 is a positive whole number.However 26-40 = -14 which is clearly not a positive whole number. So positive whole numbers are not closed under subtraction.
