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, $-83-30=-113$ .

$-113$
