Mathematics
1 answer:
anastassius [24]2 years ago
5 0

Answer:

-113

Step-by-step explanation:

Let's use the Decomposition Method.

1) Use this rule: -a-b=-(a+b).

-(83+30)

2) Use the decomposition method.

83 = 80 + 3

30 = 30 + 0

_____________________

            110 + 3 = 113

3) After simplification, we have:

-(83+30)=-113

4) Therefore, -83-30=-113.

-113
