To add 10.82 and -15.96, follow these steps:
Step 1: Write down the two numbers vertically, with the decimal points aligned:

-15.96
------
8
Step 3: Move to the next column (the tenths column). Subtract the digits in that column:
10.82
-15.96
------
86
Step 4: Move to the next column (the hundredths column). Subtract the digits in that column:
10.82
-15.96

Step 5: Finally, combine the whole number part (if any) with the decimal part:
10.82 + (-15.96) = -5.14

To add 10.82 and -15.96, you can follow these simple steps:
1. Start by writing down the two numbers vertically, with the decimal points aligned.
```
10.82
