    59°56'15''
    257°51'35''
    --------------
    358°228'63''
    +3° +1' -60''
    ---------------
    361°229'3''
    -180'

    12 + 56 + 51 isn't 228.

    add these together:
    deg = 42 mins= 12 secs= 13
    deg = 59 mins= 56 secs= 15
    deg =257 mins= 51 secs= 35
    totals:
    deg =358 mins=119 secs=305
    Divide seconds by 60 -> that result is added to minutes, with remainder in seconds
    we get 5 minutes and 5 seconds leftover
    deg =358 mins=124 secs=5
    Divide minutes by 60 -> that result is added to degrees, with remainder in minutes
    we get 2 degrees and 4 minutes leftover
    deg =360 mins=4 secs=5
