Consider the following situations:. Closure Property MathBitsNotebook. A set is closed under an operation if and only if the operation on any two elements of the set produces another element of the same set. If the operation produces even one element outside of the set, the operation is not closed. Since 2. There are also other examples that fail. All that is needed is ONE counterexample to prove closure fails.

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. Closed under addition means that t he quantities being added satisfy the closure property of addition , which states that the sum of two or more members of the set will always be a member of the set. Whole numbers, for example, are 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.
