Answer 1

To calculate \(-123.45 - (-234.76)\) using the additive inverse, we can rewrite the expression:

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

Now, we can perform the addition:

\[
234.76 - 123.45
\]

Aligning the numbers for addition:

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

Now, we perform the addition step-by-step:

1. **Take the decimals into account:**
- \[ 234.76 \]
- \[ -123.45 \]
- Start from the rightmost side.

2. **Adding the hundredths:**
- \(6 + 5 = 11\) (write 1 and carry over 1)

3. **Adding the tenths:**
- \(7 + 4 + 1 (carry) = 12\) (write 2 and carry over 1)

4. **Adding the units:**
- \(4 + 3 + 1 (carry) = 8\)

5. **Adding the tens:**
- \(2 + 2 = 4\)

So the addition looks like this:
```
234.76
- 123.45
---------
111.31
```

Thus, the final result is:

\[
-123.45 + 234.76 = 111.31
\]

Therefore, the answer is **111.31**.
