I have a series of times that are 11 minutes and less and want to add them
but cannot figure out how. I found the format [mm]:ss but don't know how to
use it

Just use SUM as with any number.

Use the SUM function and format the cell as [mm]:ss.

=SUM(A1:A10)

Then format the formula cell as [mm]:ss

The [ ] keep the minutes from rolling over into hours.

Without the [ ] :

61 minutes 10 secnds would display as:

01:10

With the [ ] it would display as:

61:10

One problem is that if you try to enter times in minutes and seconds, Excel
will tend to treat it as hours and minutes.

If you type in 12:34, Excel will read it as 12:34:00
To get 0:12:34, you need to type either 0:12:34 or 12:34.0

If you've already got all your times in the system and they are hours and
minutes, you can turn them to minutes and seconds by putting 60 into a spare
cell, select and copy, then select your range of times, Edit/ Paste special,
divide.
