Here we will show you step-by-step how to calculate 65 minus 86 using the long subtraction method.
Before we continue, note that 65 is called the minuend and 86 is called the subtrahend.
To solve the problem 65 minus 86 using long subtraction, we first put the largest number on top and the smallest number at the bottom like this:
| 8 | 6 | |||||||
| - | 6 | 5 | ||||||
Then you subtract the ones digits (6 - 5 = 1) like this:
| 8 | 6 | |||||||
| - | 6 | 5 | ||||||
| 1 |
Next you subtract the tens digits (8 - 6 = 2) like this:
| 8 | 6 | |||||||
| - | 6 | 5 | ||||||
| 2 | 1 |
Note that since the minuend is smaller than the subtrahend, the answer is a negative number.
And that's it. The problem with the answer is displayed below:
65 - 86 = -21
