- Closure property: For any two whole numbers, a and b, if a > b then a – b is a whole number and if a < b then a – b is never a whole number. ...
- Commutative property: For any two whole numbers a and b, a – b ≠ b – a . Hence subtraction of whole number is not commutative. ...
- Associative property:
