A set has closure under an operation if performance of that operation on members of the set always produces a member of the same set; in this case we also say that the set is closed under the operation.
A closure property is a certain rule that holds <u>if it is true for all elements of a set under the given operation</u> and a closure property does not hold <u>if there is at least one pair of elements that do not follow the closure property under the given operation.</u>

Now I feel guilty and sleezy. Giving answers alone without explanations
is something I almost never do, because it doesn't help anybody do

along and decides to delete this because of no explanations, then let him
delete it. It'll serve us right, you and me both.
