=75-（6.8+0.4*0.8*0.25*12.5）
=75-[6.8+(0.4*0.25)*(0.8*12.5)]
=75-(6.8+0.1*10)
=75-7.8
=67.2
=75-[6.8+(0.4*0.25)*(0.8*12.5)]
=75-(6.8+0.1*10)
=75-7.8
=67.2

=75-(6.8+0.4*0.25+12.5*0.8)
=75-(6.8+0.1+10)
=75-16.7
=59.3
=75-(6.8+0.1+10)
=75-16.7
=59.3

75-(6.8+0.8*0.4*0.25*12.5)
=75-(0.8*12.5)*(0.4*0.25)-6.8
=75-10*0.1-6.8
=75-1-6.8
=74-6.8
=67.2
=75-(0.8*12.5)*(0.4*0.25)-6.8
=75-10*0.1-6.8
=75-1-6.8
=74-6.8
=67.2

解：
75-（6.8+0.32*0.25*12.5）
=75-(6.8+0.4*0.8*0.25*12.5)
=75-[6.8+(0.4*0.25)*(0.8*12.5)]
=75-[6.8+0.1*10]
=75-[6.8+1]
=75-7.8
=67.2
75-（6.8+0.32*0.25*12.5）
=75-(6.8+0.4*0.8*0.25*12.5)
=75-[6.8+(0.4*0.25)*(0.8*12.5)]
=75-[6.8+0.1*10]
=75-[6.8+1]
=75-7.8
=67.2

原式
=75-（6.8+0.4*0.8*0.25*12.5）
=75-[6.8+(0.4*0.25)*(0.8*12.5)]
=75-(6.8+0.1*10)
=75-7.8
=67.2
=75-（6.8+0.4*0.8*0.25*12.5）
=75-[6.8+(0.4*0.25)*(0.8*12.5)]
=75-(6.8+0.1*10)
=75-7.8
=67.2
