4 − 9 = −5. Select all correct answers for each question. They are not closed under division because, for example, 1, 0 ∈ r but 1 ÷ 0 is not a member (in fact it is undefined).

Whole numbers are not closed under subtraction. Now,take any 2 numbers and add them. This smallest closed set is called the closure of s (with respect to these operations). 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.
