we combine the parts of our answer to write it in standard form. The
answer in subtraction is called the difference .
Example 1

80 5
Find the difference between
85 and 23 using expanded form.
23 S
− 20 3
80 5
− 20 3
60 2
80 5
− 20 3
60 2 S 62
The difference is 62.
We can also use expanded form to subtract three-digit numbers.
Example 2
589
Find the difference between
500 80 9
589 and 262 using expanded form.
262 S
− 200 60 2
500 80 9
− 200 60 2
300 20 7
500 80 9
− 200 60 2
300 20 7 S 327
