Lesson Twenty-one: Carrying

Take a look at this example: 

  350
  +50
  ----
  400
If we do this problem step-by-step we perform the following steps: 

  STEP ONE       STEP TWO        STEP THREE
                   1               1
   350             350             350
   +50             +50             +50
  -----           -----           -----
     0              00             400

  add ones       add tens        add hundreds
                 and carry

Here's another example:
