adding/subtracting of degrees works like add/subtract in units of time
we have to "borrow" a degree
22degrees33' - 10degrees54'
= 21° 93' - 10° 54'
= 11° 39'
look at your calculator
If you have a key labeled D°M'S
then you can do the operation directly.
follow these keystrokes
22
D°M'S

10
D°M'S

and you should get 11°39'00.00
(the last part would be seconds, we did not have any)
22degrees33' - 10degrees54'
