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 law of closure is a visual perception law—or Gestalt principle—that describes how humans have a natural inclination to perceive incomplete or fragmented visual elements as a complete object. The brain typically fills in the gaps in an image where there are missing parts to perceive a unified and coherent form.
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.
The set of real numbers is closed under multiplication. If you multiply two real numbers, you will get another real number. There is no possibility of ever getting anything other than another real number.

Closure property holds for addition and multiplication of whole numbers. Closure property of whole numbers under addition: The sum of any two whole numbers will always be a whole number, i.e. if a and b are any two whole numbers, a + b will be a whole 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.
The associative property states that the sum or the product of three or more numbers does not change if they are grouped in a different way. This associative property is applicable to addition and multiplication. It is expressed as, (A + B) + C = A + (B + C) and (A × B) × C = A × (B × C).
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.
