Natural numbers are a set of numbers starting from 1 counting to infinity. The set of natural numbers is denoted as ′N′. Whole numbers are a set of numbers starting from 0, going up to infinity. Basically, they are natural numbers with zero added to the set. The set of whole numbers is denoted as ′Closure Property’. Closure property is applicable for whole numbers in the case of addition and multiplication while it isn’t in the case of subtraction and division. This applies to natural numbers as well. Commutative Property Commutative property applies for whole numbers and natural numbers in the case of addition and multiplication but not in the case of subtraction and division. Associative Property Associative property applies for whole numbers and natural numbers in the case of addition and multiplication but not in the case of subtraction and division.
