Lesson

Sometimes a number has digits that are zeros. When this happens

in expanded subtraction, we need to use a placeholder.

Example 3

Find the difference between 479 and 204 using expanded form.

479

400 70 9

 204 S

− 200

0 4

− 200

0 4

200 70 5 S 275

Notice that there are 0 tens in 204. The 0 is written as a placeholder,

and we subtract 70 − 0 in the tens place. The other digits are

subtracted as usual.

The difference is 275.

Sometimes when we subtract, the amount of digits in each number

is not the same. For example, we can subtract a two-digit number from

a three-digit number.

Example 4

Find the difference between 586 and 61 using expanded form.

586

500 80 6

 61 S

−

60 1

−

60 1

500 20 5 S 525

There are no hundreds in 61, so we do not need to write a 0 in the

hundreds place. The other digits are subtracted as usual.

The difference is 525.
