Add the following decimals.
`2.3667+2.57+3.22`

Answer

To solve the problem of adding the decimals \(2.3667\), \(2.57\), and \(3.22\), we will follow these steps:

### Step 1: Align the Decimals
First, we need to write the numbers in a column format, aligning the decimal points. To do this, we will convert each decimal to have the same number of digits after the decimal point.

### Step 2: Convert to Like Decimals
The maximum number of digits after the decimal point among the three numbers is 4 (from \(2.3667\)). We will adjust the other two numbers to have 4 digits after the decimal point by adding zeros.

- \(2.3667\) remains \(2.3667\)
- \(2.57\) becomes \(2.5700\)
- \(3.22\) becomes \(3.2200\)

Now we have:
```
2.3667
+ 2.5700
+ 3.2200
```

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

1. **Thousandths place**: \(7 + 0 + 0 = 7\)
2. **Hundredths place**: \(6 + 0 + 0 = 6\)
3. **Tenths place**: \(6 + 7 + 2 = 15\) (write down 5 and carry over 1)
4. **Units place**: \(2 + 2 + 3 + 1 (carry) = 8\)

Putting it all together, we get:
```
2.3667
+ 2.5700
+ 3.2200
---------
8.1567
```

### Final Answer
The sum of \(2.3667 + 2.57 + 3.22\) is \(8.1567\).
