1. a. division (i.e. 3 / 4 = .75)

b. division (i.e. 5 / 0 = no solution. You can’t divide by a zero)

c. division (-5 / 2 = -2.5)

d. multiplication (9 * 3 = 27)

2. whole numbers are closed under addition. a whole number plus a whole number will always give you a whole number.

3. integers under division (shown above)

4. I don’t think so. There can be sets of 3 (-1, 0, 1) or (0, 1, 2), but I can’t think of one that is 4 numbers. I’m not positive on that though.
