Answer :

Sure! Let's look at how to solve the problem step by step:

We need to find the sum of three numbers: 5.82, 1.69, and 2.3.

### Step-by-Step Solution:

1. Align the decimal points:
```
5.82
+ 1.69
+ 2.30
```

2. Add the hundredths place:
```
5.82
+ 1.69
+ 2.30
-----
1 (carry 1 to the tenths place)
```

3. Add the tenths place:
```
5.82
+ 1.69
+ 2.30
------
19 (including the carry 1 from the hundredths place, we get 19 in the tenths place. So, write down 9 and carry over 1 to the units place)
```

4. Add the units place:
```
5.82
+ 1.69
+ 2.30
-----
9.81 (including the carry 1 from the tenths place)
```

So, the sum of 5.82, 1.69, and 2.3 is 9.81.
