Question

what is closure property?​

Answer 1

$\huge\underline\bold\green{Answer}$

A set that is closed under an operation or collection of operations is said to satisfy a closure property. Often a closure property is introduced as an axiom, which is then usually called the axiom of closure.

For example, the set of even integers is closed under addition, but the set of odd integers is not.

Answer 2

Closure properties say that a set of numbers is closed under a certain operation if and when that operation is performed on numbers from the set, we will get another number from that set back out. Real numbers are closed under addition and multiplication.

basically it is when the sum of two or more whole number/integer is equal to an whole number/integer

example:17+3=20

17and 3 both are whole numbers and there sum which 20 is also a whole number so closure is closed under addition

example2:17-3=-17

as -17 is not a whole number so subtraction is not closed under closure property

I hope this helps you
