6050-6300/42
=6050-7*6*150/(7*6)
=6050-150
=5900
(2.5-2.5*0.6)/4
=2.5(1-0.6)/4
=2.5*0.4/4
=2.5*0.1
=0.25
(315+270)/(1.3*5)
=585/(1.3*5)
=(13*5*9)/(1.3*5)
=10*9
=90
祝你开心

6050-6300/42
=6050-900*7/6*7
=6050-900/6
=6050-150
=5900
(2.5-2.5*0.6)/4
=2.5*(1-0.6)/4
=2.5*0.4/4
=2.5*0.1
=0.25
(315+270)/(1.3*5)
=(45*7+45*6)/(1.3*5)
=45*(7+6)/(1.3*5)
=45*10/5
=90

分别是5900
0.25
90

最好的简便运算就是你通过几种不一样的方法计算哪个最少步骤,就可以了~!
