Arithmetic Grade Five

Lesson Twenty-three: Carrying

Take a look at this example: 

  3500
  +500
  ----
  4000
If we do this problem step-by-step we perform the following steps: 

  STEP ONE         STEP TWO        STEP THREE       STEP FOUR
                                     1                1
   3500             3500             3500             3500
   +500             +500             +500             +500
  ------           -------          -------          -------
      0               00              000             4000

  add ones       add tens        add hundreds        add thousands
                                  and carry

Here's another example: 

   6600
   +400
   ----
