The first thing you need to do is determine what amounts of time you were wanting to add together.

The second step is to change the times into digit format, so that each one looks like this: 2 hours and 34 minutes will become 234, while 5 hours and 27 minutes will become 527. Or, for larger numbers such as: 35 hours and 15 minutes it would be 3515. Or: 34257 (342 hours and 57 minutes) No matter how large the amount of time is, convert it into simple digit format.

Next, simply add them together. 234 + 527 = 761.

The last two digits of your answer will be your minutes. So with the above example, your answer would be 7 hours and 61 minutes (761).

Remember, the last two digits of your answer will represent the minutes, all the rest will be hours. In the above example, the minutes equaled 61. Since an hour only has 60 minutes to it, we will convert by using the following trick. Whenever the last two digits of the sum are 60 or greater, add an ADDITIONAL 40 to whatever the sum is. So: 761 + 40 = 801. Your answer is 8 hours and 1 minute.

Let’s do another quick one. 6 h/ 39 m. plus 7 h/ 48 m. 639+748= 1387. Add the ADDITIONAL 40 because the last two digits (87) are greater than 60. 1387 + 40 = 1427. Your answer is 14 hours and 27 minutes.

Good for you, now you can add time like a pro! Now go out and impress your friends and family!
