Positive 12 plus negative 18 equals negative 6. This is because when you add a positive number to a negative number, you effectively subtract the smaller absolute value from the larger absolute value. In this case, 18 is larger than 12, so 18 minus 12 equals 6, and since the result is from a negative number, the final answer is negative 6.
Rule: Positive + Positive = Positive 12+12=24 Positive - Positive = Positive or Negative 12-6=6 | 12-13=(-1) Positive + Negative = Greater numbers sign in the answer 14+(-18)=(-4) | 18+(-14)=4 Positive - Negative = Positive 8-(-8)=16 Negative + Negative = Negative -12+(-12)=(-24) Negative - Negative = Positive or Negative (-8)-(-9)=1 | (-8)-(-7)=(-1) by, Patrick Macarilay AKA, macason
-12 + 18 - (-15) = -12 + 18 +15 = 21

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

-12 + 18 - (-15) = -12 + 18 +15 = 21
When subtracting a negative number, you can think of it as adding the positive equivalent. In this case, 18 minus a negative 18 is the same as 18 plus 18, which equals 36. This is because subtracting a negative number is equivalent to adding its positive counterpart.

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
3 + (-21) = 3 - 21 = -18
