That's incorrect.
20 + (-5) + (-5) + (-5) + (-5) = 20 - 20 = 0
20 + (-5) + (-5) + (-5) + (-5) = 20 - 20 = 0
1. Start by adding the positive number 20 to the negative numbers (-5, -5, -5, -5).
20 + (-5) + (-5) + (-5) + (-5) = 20 + 4(-5)
2. Multiply 4 by -5.
20 + 4(-5) = 20 - 20
3. Simplify the addition.
20 - 20 = 0
Therefore, the final result of the expression 20 + (-5) + (-5) + (-5) + (-5) is 0.
