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.
The set of real numbers is closed under addition. If you add two real numbers, you will get another real number. There is no possibility of ever getting anything other than a real number. For example: 5 + 10 = 15 , 2.5 + 2.5 = 5 , 2 1 2 + 5 = 7 1 2 , 3 + 2 3 = 3 3 , etc.
The associative property holds true in case of addition and multiplication of natural numbers i.e. a + ( b + c ) = ( a + b ) + c and a × ( b × c ) = ( a × b ) × c. On the other hand, for subtraction and division of natural numbers, the associative property does not hold true.
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.
Closure property means when you perform an operation on any two numbers in a set, the result is another number in the same set or in simple words the set of numbers is closed for that operation.
The closure property states that if a set of numbers (integers, real numbers, etc.) is closed under some operation (such as addition, subtraction, or multiplication, etc.), then performing that operation on any two numbers in the set results in the element belonging to the set.

Conclusion. Natural numbers form the foundation of the number system, containing all positive integers from 1 to infinity.
