FAQ
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 closure property states that for any two rational numbers a and b, a + b is also a rational number. The result is a rational number. So we say that rational numbers are closed under addition.
Closure property is one of the basic properties used in math. By definition, closure property means the set is closed. This means any operation conducted on elements within a set gives a result which is within the same set of elements. Closure property helps us understand the characteristics or nature of a set.
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 rational numbers under subtraction: The difference between any two rational numbers will always be a rational number, i.e. if a and b are any two rational numbers, a – b will be a rational number.
In addition, we have proved that even the set of irrationals also is neither open nor closed.
Irrational numbers are not closed under addition, subtraction, multiplication, and division.
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).
Closure property For two rational numbers say x and y the results of addition, subtraction and multiplication operations give a rational number. We can say that rational numbers are closed under addition, subtraction and multiplication. For example: (7/6)+(2/5) = 47/30.
