Closure Property

Pronunciation: /ˈkloʊ.ʒər ˈprɒp.ər.ti/ Explain

The closure property of real numbers means that for any two real numbers a and b, a + b is a real number and a·b is a real number.[2]

We say that the set of real numbers is closed with respect to addition and multiplication. As a general principle, set closure applies to many other sets and operations.
