Natural numbers are a part of the number system which includes all the positive integers from 1 till infinity and are also used for counting purpose. It does not include zero (0). In fact, 1,2,3,4,5,6,7,8,9…., are also called counting numbers.
Natural Numbers Natural number + Natural number = Natural numberClosed under addition Natural number x Natural number = Natural number Closed under multiplication Natural number / Natural number = Not always a natural number Not closed under division1 more row
Closure Property A natural number is closed under addition and multiplication. This means that adding or multiplying two natural numbers results in a natural number. However, for subtraction and division, natural numbers do not follow closure property. When a and b are two natural numbers, a+b is also a natural number.

The Closure Properties For example, - The real numbers are not closed under division since, although 5 and 0 are real numbers, 5/0 and 0/0 are not real numbers. - The natural numbers are not closed under subtraction since, although 8 is a natural number, 8−8 is not. (8−8=0 and 0 is not a natural number).

The closure property of addition states that when any two elements of a set are added, their sum will also be present in that set. The closure property formula for addition for a given set S is: ∀ a, b ∈ S ⇒ a + b ∈ S.
Closure property of natural numbers states that the. Let's check for all four arithmetic operations and for all a, b ∈ N. Addition: 1 + 5 = 6, 7 + 4 = 11, etc. Clearly, the resulting number or the sum is a natural number.
Closure property under multiplication states that any two rational numbers' product will be a rational number, i.e. if a and b are any two rational numbers, ab will also be a rational number. Example: (3/2) × (2/9) = 1/3.
