Reference Example 9

Subtract: 42,403 – 1,675

Strategy We will write the subtraction in vertical form. To subtract in the ones column, we will borrow from the hundreds column of the minuend 42,403.

Why Since the digit in the tens column of 42,403 is 0, it is not possible to borrow from that column.

Solution

We write the subtraction in vertical form so that the corresponding digits are lined up. Each step of this subtraction is explained separately. Your solution should look like the last step.

Since 5 in the ones column of 1,675 is greater than 3 in the ones column of 42,403, we cannot immediately subtract. It is not possible to borrow from the digit 0 in the tens column of 42,403. We can, however, borrow from the hundreds column to regroup in the tens column, as shown on the next page. In this process, we use the fact that 1 hundred = 10 tens.
