How to add or subtract 2 times, calculation with the calculator of windows 7?

For example:

I want to add 2 different times as follows. More time is with the format hours: Minutes: seconds.

H MM SS

01:50:31

+ 2:20:30

-------------------

04:11:01

How to perform this calculation of time with Windows 7 or any other Calculator calculator in Windows 7.

Response.

In your example:

First add the hours, the minutes and the dry separately

Hours = 1 + 2 = 3

MN = 50 + 20 = 70

Seconds = 31 + 30 = 61

Now, to calculate whole minutes because of the second column:

61 seconds/60 = 1.016 mins (approx.)

Ignore the bits after the comma, and add whole minutes in the minutes column:

MN = 70 + 1 = 71

Calculate the seconds remaining:

61. 60 = 1 second.

Now, calculate hours because of the minutes column:

71minutes/60 = 1.183 hours (approx.)

Ignore the bits after the comma and add hours to the column of the hours:

Hours = 3 + 1 = 4

Calculate the remaining minutes:

71 60 = 11 min.

That is why total is:

4 hours, 11 minutes, 1 second.

The calculator is not a huge help to make these kinds of calculations because it works in decimal which means he cannot directly calculate/convert seconds/minutes/hours located in several of the early 1960s. If you had a spreadsheet like Excel you could set up (with a little work) to do this kind of thing.
