To find the sum of two numbers using the additive inverse, we can add the opposite of the second number to the first number.
The opposite of -871.78 is 871.78 (since a number and its opposite add up to zero).
So, -492.89 - (-871.78) becomes -492.89 + 871.78.
Adding these two numbers:
-492.89 + 871.78 = 378.89
Therefore, -492.89 - (-871.78) = 378.89.
