Jika a=15 derajat 20' 11'' ,b=32 derajat 10' 14'',dan c=39 derajat 59' 53'',hasil a, b, dan c adlah

a  = 15° 20' 11''
b = 32° 10' 14''
c = 39° 59' 53''
----------------------------+
= 86° 89' 78''

karena 60'' = 1' dan 60' = 1° maka hasil diatas dapat disedehanakan :
= 86°(89+1)' (78-60)''
= 86° 90' 18''
= (86+1)° (90-60)' 18''
= 87° 30' 18''
