Use the additive inverse to find - 492.89 - (876.78)
To find the additive inverse of a number, we need to find a number that when added to it, will result in zero. The additive inverse of a number is the negative of that number.
In this case, the additive inverse of -876.78 is 876.78.
Therefore, -492.89 - (-876.78) is equal to -492.89 + 876.78.
Now, let's add -492.89 and 876.78:
-492.89 + 876.78 = 383.89
So, -492.89 - (-876.78) is equal to 383.89.
To find the additive inverse of a number, we simply change its sign.
Given the expression -492.89 - (876.78), first, we change the signs of both numbers inside the parentheses using the additive inverse:
- 492.89 becomes 492.89 with a positive sign, and
- 876.78 becomes 876.78 with a positive sign.
Now we can rewrite the expression as:
492.89 + 876.78
Finally, we can add these numbers together:
492.89 + 876.78 = 1369.67
Therefore, -492.89 - (876.78) is equal to 1369.67.
