Answer 1

-21

Explanation:

Answer 2

For this case we must evaluate the following expression:

`\frac {-66} {(- 3)} + (- 4) - (- 5) =`

We solve the division:

`22 + (- 4) - (- 5) =`

We eliminate parentheses keeping in mind that:

`+ * - = -\\- * - = +`

So:

`22-4 + 5 =`

Different signs are added and the same sign is placed, while different signs are subtracted and the sign of the major is placed:

`18 + 5 =\\23`

Answer:

23
