+ 12.240
+ 1.224
```

### Step 2: Add the numbers starting from the rightmost column
1. **Thousandths place**:
- \( 0 + 0 + 0 + 4 = 4 \)

2. **Hundredths place**:
- \( 0 + 0 + 4 + 2 = 6 \)

3. **Tenths place**:
- \( 0 + 4 + 2 + 2 = 8 \)

4. **Units place**:
- \( 4 + 2 + 2 + 1 = 9 \)

5. **Tens place**:
- \( 2 + 1 = 3 \)

6. **Hundreds place**:
- \( 1 = 1 \)

### Step 3: Combine the results
Putting all the results together, we get:
```
1359.864
```

Thus, the answer to the equation \( 1224 + 122.4 + 12.24 + 1.224 \) is \( 1359.864 \).

### Final Answer:
