Add 10.82+ -15.96.
Step-by-step to solve
To add 10.82 and -15.96, follow these steps:
1. Write the two numbers vertically, with the decimal points aligned:
10.82
+ -15.96
2. Start with the rightmost column (the ones place) and add the digits in that column: 2 + 6 = 8. Write the 8 below the line.
10.82
+ -15.96
8
3. Move to the next column (the tenths place) and add the digits in that column: 8 + 9 = 17. Since the sum is larger than 9, you carry over the 1 and write the units digit (7) below the line.
10.82
+ -15.96
78
4. Move to the next column (the hundredths place) and add the digits in that column: 1 + 5 = 6. Write the 6 below the line.
10.82
+ -15.96
678
5. Finally, place the negative sign in front of the sum to indicate that the result is negative:
-6.14
Therefore, 10.82 + -15.96 equals -6.14.
To add 10.82 and -15.96, follow these steps:
1. Write down the numbers vertically, aligning the decimal points:
```
10.82
+ -15.96
```
2. Ignore the signs for now and add the numbers as if they were both positive:
```
10.82
+ 15.96
-------
26.78
```
3. Now, consider the signs. Since one number is positive and the other is negative, the sum will have the sign of the larger number. In this case, since 15.96 is larger than 10.82, the result will be negative:
```
10.82
+ -15.96
-------
-4.14
```
Therefore, the answer to 10.82 + -15.96 is -4.14.
