First, we need to find the additive inverse of 5. This means finding the number that, when added to 5, results in zero. The additive inverse of 5 is -5 because 5 + (-5) = 5 + (-5*1) = 0.
Next, we can express the product of -1 and -4 as -411 = -1.
Finally, we can add the additive inverse of 5 to the product of -1 and -4 as follows: -411 + (-5) = -5. This is the result we were seeking.
