Add the following decimals.
2.237`+` 0.2113`+` 5.5664

Answer

To add the decimals 2.237, 0.2113, and 5.5664, we will follow these steps:

### Step 1: Align the decimals
First, we need to align the numbers by their decimal points. To do this, we can write the numbers one below the other:

```
2.237
+ 0.2113
+ 5.5664
```

### Step 2: Make them like decimals
Next, we need to make sure all the numbers have the same number of digits after the decimal point. The longest decimal has 4 digits (5.5664), so we will add zeros to the end of the other numbers to make them all have 4 digits:

```
2.2370
+ 0.2113
+ 5.5664
```

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

1. **Thousandths place**: 0 + 3 + 4 = 7
2. **Hundredths place**: 7 + 1 + 6 = 14 (write down 4 and carry over 1)
3. **Tenths place**: 3 + 1 + 6 + 1 (carry) = 11 (write down 1 and carry over 1)
4. **Units place**: 2 + 0 + 5 + 1 (carry) = 8

Putting it all together, we have:

```
2.2370
+ 0.2113
+ 5.5664
---------
8.0147
```

### Final Answer
The sum of 2.237, 0.2113, and 5.5664 is **8.0147**.
