288/(102-18*5) 165/[3*(27-22)] (531-513)*(79+11) [1520-(1060-80)]/9 (用递等式计算)

问题描述:

288/(102-18*5) 165/[3*(27-22)] (531-513)*(79+11) [1520-(1060-80)]/9 (用递等式计算)

288/(102-18*5)
=288/(102-90)
=288/12
=24
165/[3*(27-22)]
=55/5
=11
(531-513)*(79+11)
=18*90
=1620
[1520-(1060-80)]/9
=(1520-980)÷9
=540/9
=60
