In mathematics, a set is closed under an operation when we perform that operation on members of the set, and we always get a set member. Thus, a set either has or lacks closure concerning a given operation. In general, a set that is closed under an operation or collection of functions is said to satisfy a closure property. Usually, a closure property is introduced as a hypothesis, traditionally called the axiom of closure. The best example of showing the closure property of addition is with the help of real numbers. Since the set of real numbers is closed under addition, we will get another real number when we add two real numbers.

Closed under addition

The closure property of addition highlights a special characteristic in rational numbers among other groups of numbers. When a set of numbers or quantities are closed under addition, their sum will always come from the same set of numbers. Use counterexamples to disprove the closure property of numbers as well. This article covers the foundation of closure property for addition and aims to make you feel confident when identifying a group of numbers that are closed under addition , as well as knowing how to spot a group of numbers that are not closed under addition.

In mathematics, a subset of a given set is closed under an operation of the larger set if performing that operation on members of the subset always produces a member of that subset. Similarly, a subset is said to be closed under a collection of operations if it is closed under each of the operations individually. The closure of a subset is the result of a closure operator applied to the subset.
