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.
