48°39′+68°21′-21°17′×5
48°39′+68°21′-21°17′×5
48°39′+68°21′-21°17′×5
48°39′+68°21′-21°17′×5
=48°39′+68°21′-106°25′
=117°-106°25′
=10°35′
9°35′

=(48*60+39+68*60+21-21*60*5-17*5)/60
=(60(48+68-21*5)+39+21-17*5)/60
=(60*11-25)/60
=10。。。。。35
所以等于10°35′
48°39′+68°21′-21°17′×5
=48°39′+68°21′-(21°×5+17′×5)
=48°39′+68°21′-(105°+85′)
=116°+60′-(105°+60′+25′)
=116°+60′-(106°+25′)
=116°-106°+60′-25′
=10°+35′
=10°35′
将分化成小数点计算就OK了
