Answer:
the answer is 1
Explanation:
ok, so you see that there's a negative sign in front of (-3). even if there's no other number in front of the parentheses, there's actually a -1, its just that math omits the 1 to make life easier. With that in mind, whenever you see an even amount of negative signs, the answer's gonna be positive. In this case you just multiple -3 and the negative sign to get +3, and since there's a -2 in front of the -3, you add them together (-2+3) to get 1
Hope this isn't too much info for you :'D
