Question

-83 + -30
Integers…………….

Answer 1

-113

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`
