Question 326786: Determine if the follwing sets are closed under multiplication:
{{0,1}
Answer by JBarnum(2146)   (Show Source):
You can put this solution on YOUR website! "Closed under multiplication means that any member of the set times any other member of the set (including itself) yields another member of the set.
Note: 0×0 = 0, 0×1 = 0, 1×1 = 1
Those are all possible combinations and all yield a member of the set.
So, yes the set is closed to multiplication."
