30°31‘×5-(43°20’+=27°42‘27’‘)30°31‘×5-(43°20’+=27°42‘27’‘)30°31‘×5-(43°20’+=27°42‘27’‘)=150°155''-70°

30°31‘×5-(43°20’+=27°42‘27’‘)
30°31‘×5-(43°20’+=27°42‘27’‘)

30°31‘×5-(43°20’+=27°42‘27’‘)
=150°155'-70°60’27"
=150°154'60"-70°60’27"
=(150-70)°(154-60)’(60-27)"
=80°94’33"
=81°34’33"

43°20’+=27°42‘27’‘的 += 是什么意思,麻烦说清楚

我无视“=”
81°32′33〃
其实用计算机按一下就可以了!!!
