Here we will show you step-by-step how to calculate 66 minus 7 using the long subtraction method.
Before we continue, note that 66 is called the minuend and 7 is called the subtrahend.
To solve the problem 66 minus 7 using long subtraction, we first put the largest number on top and the smallest number at the bottom like this:
| 6 | 6 | |||||||
| - | 0 | 7 | ||||||
Then you subtract the ones digits. In this case, the subtrahend ones digit is larger than the minuend ones digit. Therefore, you have to "borrow" 10 from the minuend tens digit, which gives you 10 + 6 - 7 = 9
| 5 | 10 | |||||||
| 6 | ||||||||
| - | 0 | 7 | ||||||
| 9 |
Next you subtract the subtrahend tens digit from the new minuend tens digit. 5 - 0 = 5
| 5 | 10 | |||||||
| 6 | ||||||||
| - | 0 | 7 | ||||||
| 5 | 9 |
And that's it. The problem with the answer is displayed below:
66 - 7 = 59
