Question

If we exclude zero from the set of integers is it closed under division

Answer 1

Set of integers excluding zero are ....... -3, -2, -1, 1, 2, 3, ........These numbers are not closed under division as the quotient of two integers may not be a integer.If a and b are two integers, a/b may not be an integer.

Answer 2

No they'll not be closed under division One example = -2divided by -3 = -2/-3 -2/-3 is not an integer Thus integers are not closed under division
