When subtracting larger whole numbers,
start in the ONES column and move left.

685 - 324 =

hundreds	tens	ones
6	8	5
3	2	4

6 8 5
-3 2 4
3 6 1

because:
5-4 = 1,
8-2 = 6, and
6-3 = 3

8,479 - 2,265 =

8,479
-2,265

subtract each column:
       ones           tens           hundreds       thousands
    9-5=4 , 7-6=1, 4-2=2, 8-2=6

so, 8,479 - 2,265 = 6,214

Examples:

   958                             865                          758
- 724                             -153                         -534
   274                               712                          224

REMEMBER:

Start subtracting from the ONES column,
and move your way left !
