Answer 1

To solve \(-123.45 - (-234.76)\), we can use the additive inverse property, which states that subtracting a negative number is the same as adding its positive counterpart.

So, we rewrite the expression:

\[
-123.45 - (-234.76) = -123.45 + 234.76
\]

Now we perform the addition:

1. First, let's find the difference between the two numbers:
\[
234.76 - 123.45
\]

We can align these numbers for clarity:

```
234.76
- 123.45
__________
```

2. Now we subtract:
- Start from the rightmost column: 6 - 5 = 1
- Next column: 7 - 4 = 3
- Next column: 4 - 3 = 1
- Finally, 2 - 1 = 1

So:

\[
234.76 - 123.45 = 111.31
\]

Thus:

\[
-123.45 + 234.76 = 111.31
\]

The final answer is:

**111.31**
