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
