Which balance is 86 more than the balance of -$47.90
Where is the numberline?
To find the balance that is $86 more than a given balance, we need to add $86 to that balance. In this case, the given balance is -\$47.90.
To add $86 to -\$47.90, we can follow these steps:
1. Start with the given balance: -\$47.90
2. Add $86 to this balance: -\$47.90 + $86
To perform this addition, we need to align the decimal point and add the numbers.
- Ignore the dollar sign for now, as it doesn't affect the addition.
- Align the numbers such that the decimal point is in the same position for both numbers. In this case, we add a zero to the end of -\$47.90 to make it -\$47.90.0.
- Add the numbers: 90 + 00 = 90 and 7 + 8 = 15 (carry over the 1 to the left).
- Now, combine the results: -\$47.90.0 + $86 = -\$47.04.
So, the balance that is \$86 more than -\$47.90 is -\$47.04.
