if you have a given set of numbers, then all of them represent a set numbers belonging into a "group", there by if you have:
$$B=\left[ -1,3,6,-3 \right]$$
Then any operation done on the set "B" will be applied to all of it's components, or numbers if you prefer:
$$nB=\left[ n(-1),n(3),n(6),n(-3) \right]$$
