Answer:
-48+-12=. -60
Step-by-step explanation:
Well -48 +( -12)
Assume the plus sign is +1 ,multiply by 12 using the law of integers. that is +(-)= -. Then continue by subtracting -12 from - 48. with this another law is used -(-)= a plus . Like 48 + 12 =60.Then check for the number with the highest value to determine your answer for the sum you got. In this case negative 48 is the highest so it's negative 60
