简便运算:2.5*0.32*12.5
每一个步奏都要写出来.

简便运算:2.5*0.32*12.5每一个步奏都要写出来.
(2.5*0.4)*(0.8*12.5)
=1*10
=10

(2.5*0.4)*(0.8*12.5)=1*10=10

2.5*0.32*12.5=(2.5*0.4)*(0.8*12.5)
=10

2.5*0.32*12.5=2.5*0.4*0.8*12.5=1*10=10

2.5*0.32*12.5
=2.5*(0.4*0.8)*12.5
=(2.5*0.4)*(12.5*0.8)
=1*10
=10

2.5*0.8*0.4*12.5=2*5=10

2.5*0.32*12.5=2.5*(0.4*0.8)*12.5=(2.5*0.4)*(0.8*12.5)
=1*10=10

2.5*0.32*12.5=2.5*0.4*0.8*12.5=(2.5*0.4)*(0.8*12.5)=1*10=10

=2.5*0.4*0.8*12.5
=(2.5*0.4)*(0.8*12.5)
=1*10
=10
