To solve the expression \(-123.45 - (-234.76)\), we can use the concept of the additive inverse. The additive inverse of a number \(x\) is \(-x\).
So, \(-(-234.76)\) is simply \(+234.76\).
Now, we can rewrite the expression as:
\[ -123.45 + 234.76 \]
Next, we perform the addition:
- Calculate \(234.76 - 123.45\).
- Align the numbers:
234.76
- 123.45
---------
- Subtract:
- Start from the right:
- \(6 - 5 = 1\)
- \(7 - 4 = 3\)
- \(4 - 3 = 1\)
- \(2 - 1 = 1\)
So the result is:
\[ 234.76 - 123.45 = 111.31 \]
Thus, the final answer to \(-123.45 - (-234.76)\) is \(111.31\).
The correct response is:
111.31
