Step-by-step explanation:
17 + (-8) + (-8) = 17 + (-16)
= 1

So, add (-8)and (-8), the result will have the sign (-). -16
If two numbers have different sign, subtract and the result will have the sign of the bigger number.
17 and (-16) have different sign and the bigger number sign is +
So, the result is 1
