Answer 1

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:

1. Calculate \(234.76 - 123.45\).
2. Align the numbers:

```
234.76
- 123.45
---------
```

3. 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**
