Problem 6. Let R", Z", Nª be the set of n x 1 matrices (column vectors) having real, integer, and nonnegative integer entries, respectively. (N = {0, 1, 2, 3, ...}.) For each of the sets R", Z", N", show whether or not it (a) is closed under addition, (b) is closed under real scalar multiplication, (c) contains an additive identity (zero vector), (d) contains the additive inverse of each of its elements.
