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.
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.
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.
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.
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.

Rational numbers are closed under addition, subtraction, and multiplication but not under division.
The Closure Property: The closure property of a whole number says that when we add two Whole Numbers, the result will always be a whole number. For example, 3 + 4 = 7 (whole number).
The closure property of rational numbers states that when any two rational numbers are added, subtracted, or multiplied, the result of all three cases will also be a rational number.
