Add the following decimals.
`9.176+1.66`

Answer

To solve the problem of adding the decimals 9.176 and 1.66, we will follow these steps:

### Step 1: Align the decimals
First, we need to write the numbers one below the other, aligning the decimal points:

```
9.176
+ 1.660
```

### Step 2: Convert to like decimals
Since 1.66 has only two decimal places, we can add a zero to make it three decimal places (1.660). This does not change its value:

```
9.176
+ 1.660
```

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

- **Thousandths place**: 6 + 6 = 12. Write down 2 and carry over 1.
- **Hundredths place**: 7 + 6 + 1 (carry) = 14. Write down 4 and carry over 1.
- **Tenths place**: 1 + 1 + 1 (carry) = 3. Write down 3.
- **Units place**: 9 + 1 = 10. Write down 0 and carry over 1 to the next whole number.

Putting it all together, we get:

```
9.176
+ 1.660
-------
10.836
```

### Step 4: Write the final answer
The sum of 9.176 and 1.66 is 10.836.

### Final Answer:
**10.836**
