Add :
23.71,9.9,4.023

Answer

To solve the problem of adding the numbers 23.71, 9.9, and 4.023, we will follow these steps:

### Step 1: Align the Numbers
First, we need to align the numbers by their decimal points. It helps to write them in a column format:

```
23.710
+ 9.900
+ 4.023
```

### Step 2: Add Zeros for Consistency
To make it easier to add, we can add zeros to the numbers so that they all have the same number of decimal places. We can write 9.9 as 9.900:

```
23.710
+ 9.900
+ 4.023
```

### 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: 0 + 0 + 3 = **3**
2. Hundredths place: 1 + 0 + 2 = **3**
3. Tenths place: 7 + 9 + 0 = **16** (write down 6 and carry over 1)
4. Units place: 3 + 9 + 4 + 1 (carry) = **17** (write down 7 and carry over 1)
5. Tens place: 2 + 0 + 0 + 1 (carry) = **3**

Putting it all together, we get:

```
23.710
+ 9.900
+ 4.023
---------
37.633
```

### Final Answer
The sum of 23.71, 9.9, and 4.023 is **37.633**.
