Answer

To add the decimals 9.7, 13.85, 126.05, and 8.796, we will follow these steps:

### Step 1: Align the numbers by their decimal points
We write the numbers one under the other, ensuring that the decimal points are aligned:

```
9.700
13.850
126.050
+ 8.796
```

### Step 2: Fill in any missing decimal places with zeros
To make it easier to add, we can add zeros to the right of the decimal points where necessary:

```
9.700
13.850
126.050
+ 8.796
```

### Step 3: Add the numbers starting from the rightmost column
We will add the numbers column by column, starting from the rightmost column (thousandths place):

1. **Thousandths place**: 0 + 0 + 0 + 6 = 6
2. **Hundredths place**: 0 + 5 + 5 + 9 = 19 (write down 9 and carry over 1)
3. **Tenths place**: 7 + 8 + 0 + 7 + 1 (carry) = 23 (write down 3 and carry over 2)
4. **Units place**: 9 + 3 + 6 + 8 + 2 (carry) = 28 (write down 8 and carry over 2)
5. **Tens place**: 1 + 2 (carry) = 3

### Step 4: Write down the final sum
Now we combine all the parts together:

```
9.700
13.850
126.050
+ 8.796
---------
158.396
```

### Final Answer
The sum of 9.7, 13.85, 126.05, and 8.796 is **158.396**.
