  • Add the minutes together.
  • Add the seconds together.
  • If the number of seconds is 60 or more do the following:
    • Subtract 60 from the number of seconds.
    • Increase the number of minutes by one.
    • Repeat this process if the number of seconds is still 60 or more.

Example: Add 4 minutes 21 seconds plus 2 minutes 47 seconds.

  • Add the minutes together. (4 minutes + 2 minutes = 6 minutes)
  • Add the seconds together. (21 seconds + 47 seconds = 68 seconds)
  • If the number of seconds is 60 or more do the following:
    • Subtract 60 from the number of seconds. (68 seconds - 60 seconds = 8 seconds)
    • Increase the number of minutes by one. (6 minutes + 1 minute = 7 minutes)
    • Repeat this process if the number of seconds is still 60 or more.
