What would the sum of -18-(-12) be?
Mademuasel [1]
-18-(-12)=-6 
Since there is two negative sign, it turns into positive meaning the -12 becomes positive 12 and the -18 stays same. So -18+12=-6 because 18 is bigger than 12 and it's negative so the final answer should be negative. 
Hint: when you see two negative sign just turn them into plus sign.
