For example, 1 … WebClosure property states that when a set of numbers is closed under any arithmetic operation such as addition, subtraction, multiplication, and division, it means that when …
WebOct 6, 2024 · 1) The set of integers is a group under the OPERATION of addition: We have already seen that the integers under the OPERATION of addition are CLOSED, ASSOCIATIVE, have IDENTITY 0, and that any integer x has the INVERSE −x. Therefore, the set of integers under subtraction is not a group! Webto get a number that is not in the set. We say that the whole numbers are closed under addition and multi-plication, but the set of whole numbers is not closed under subtraction. If we enlarge our set to be the integers {...,−3,−2,−1,0,1,2,3,...} we get a set that is closed under addition, subtraction and multiplication. These opera-

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. For example, the natural numbers are closed under addition, but not under subtraction: 1 − 2 is not a natural number, although both 1 … See more Let S be a set equipped with one or several methods for producing elements of S from other elements of S. A subset X of S is said to be closed under these methods, if, when all input elements are in X, then all possible results are … See more A binary relation on a set A can be defined as a subset R of $${\displaystyle A\times A,}$$ the set of the ordered pairs of elements of A. The notation $${\displaystyle xRy}$$ is commonly used for $${\displaystyle (x,y)\in R.}$$ Many properties or … See more In topology and related branches, the relevant operation is taking limits. The topological closure of a set is the corresponding closure operator. The Kuratowski closure axioms characterize this operator. See more • In matroid theory, the closure of X is the largest superset of X that has the same rank as X. • The transitive closure of a set. • The algebraic closure of a field. See more In the preceding sections, closures are considered for subsets of a given set.

We can say that rational numbers are closed under addition, subtraction and multiplication. For example: (7/6)+ (2/5) = 47/30 (5/6) – (1/3) = 1/2 (2/5).

Whole numbers are not closed under subtraction operation because when any two whole numbers are considered and from them one is subtracted from the other, the difference obtained is not necessarily a whole number.
