EXAMPLE

Subtract: 59 − 27

Strategy 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.

WHY 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.

Solution

We start at the right and subtract the ones digits and then the tens digits, and write each difference below the horizontal bar.

The difference is 32.
