-18. Subtracting a positive number has the same effect as adding a negative.
Negative 18 minus positive 12 is negative 30.
16 positive is.

11+-18 you are adding a negative so you take 18-11=7 and the answer is the opposite of that answer, so -7
[(-4)(-3)]=-4•-3=-12 but since they're both negative the answer is positive so it's +12 + 6= 18
With addition, a larger negative. -3 -6 +------- -9 -6 -3 x----- +18
3 + (-21) = 3 - 21 = -18
