Add the hours, the minutes, and the seconds, separately. If you get 60 or more seconds, you need to "carry over" to the minutes. You do this by subtracting 60 seconds and adding one minute. Similarly, if you get 60 or more minutes, you need to "carry over" to the hours. Here, too, you would subtract 60 from the minutes, and add 1 to the hours.
