No. Integers are not closed under division because they consist of negative and positive whole numbers. NO FRACTIONS!No.For a set to be closed under an operation, the result of the operation on any members of the set must be a member of the set.When the integer one (1) is divided by the integer four (4) the result is not an integer (1/4 = 0.25) and so not member of the set; thus integers are not closed under division.
There are an infinite number of operations for integer and different rules will apply for different operations. The question needs to be more specific.
Non-positive integers are zero and the negative integers.
The set of integers represents the integers.
