    This is kind of a fun question :) For closure, we need to stay within the set when we perform the operation.

    Let's try some multiplication: 0 x 0 = 0 0 x 1 = 0 1 x 1 = 1 We ended up with only 0's and 1's! Good, we're closed under multiplication, ya? :) We stayed within the set of {0,1} when we performed multiplication. You could set up a table I suppose, if that's easier.

    For closure, we need to get only 0's and 1's in those four remaining boxes.

    Kitten click the little `pencil` in the upper right corner of the drawing :) It will make a copy, then fill in the spaces. 1 + 1 goes in the bottom right corner for example
