Question

Quizplus · Accepted Answer

The set W - {10} is not specified, but assuming W refers to a general set from which the number 10 is excluded, without knowing the elements of W, we cannot definitively say it is closed under multiplication. However, if we interpret W - {10} as a set of whole numbers excluding 10, then it is not closed under multiplication because multiplying certain elements (e.g., 2 and 5) would result in an element (10) that is not in the set.
