Here we will show you step-by-step how to calculate 3 minus 23 using the long subtraction method.
Before we continue, note that 3 is called the minuend and 23 is called the subtrahend.
To solve the problem 3 minus 23 using long subtraction, we first put the largest number on top and the smallest number at the bottom like this:
| 2 | 3 | |||||||
| - | 0 | 3 | ||||||
Then you subtract the ones digits (3 - 3 = 0) like this:
| 2 | 3 | |||||||
| - | 0 | 3 | ||||||
| 0 |
Next you subtract the tens digits (2 - 0 = 2) like this:
| 2 | 3 | |||||||
| - | 0 | 3 | ||||||
| 2 | 0 |
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:
3 - 23 = -20
