59 − 27
Answer = (1)
Correct Answer
(1) 32
Explanation
We will write the subtraction in vertical form with the ones digits in a column and the tens digits in a column. Then we will subtract the digits in each column, working from right to left.
Like money, where pennies are only subtracted from pennies and dimes are only subtracted from dimes, we can only subtract digits with the same place value–ones from ones and tens from tens.
We start at the right and subtract the ones digits and then the tens digits, and write each difference below the horizontal bar.
| Tens column |
Ones column |
||
| ↓ | ↓ | ||
| 5 | 9 | ||
| − | 2 | 7 | |
| 3 | 2 | ← The answer (difference) |
Difference of the ones digits: Think 9 − 7 = 2.
Difference of the tens digits: Think 5 − 2 = 3.
Difference of the tens digits: Think 5 − 2 = 3.
The difference is 32.
