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.

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.

Ros–łanowski and V. Dubois D. Michalewicz eds. This definition is generalized so as to fit an ordered fuzzy number with an upper semi-continuous membership function. The main aim of this paper is to modify the arithmetic in such a way that the space of ordered fuzzy numbers is closed under the modified arithmetic operations. Moczulski eds. Szukanie zaawansowane.
