小学脱式计算:18-(1.4×1.25×2.4),列出算式给我,
18-(1.4×1.25×2.4)
=18-4.2
=13.8

18-(1.4×1.25×2.4)
=18-(1.4x1.25x3x0.8)
=18-1.4x3x1
=18-4.2
=13.8

18-{(1+0.4)×1.25×(2+0.4)}=18-{(1×1.25+0.4×0.25)×(2+0.4)}=18-{1.35×(2+0.4)}=18-4.2=13.8

18-(1.4×1.25×2.4)
=18-(1.25×8×1.4×0.3)
=18-(10×1.4×0.3)
=18-(14×0.3)
=18-4.2
=13.8

18-(0.2*7*1.25*0.3*8)
=18-(10*1.4*0.3)
=18-4.2=13.8

=18-(1.4*0.3*1.25*8)
=18-(0.42*10)
=18-4.2
=13.8

18-(1.4*1.25*2.4)
=18-(1.75*2.4)
=18-4.2
=13.8
乘号不会打,将就一下吧。嘻嘻

18-(1.4×1.25×2.4)
=18-(1.75 2.4)
=18-4.2
=13.8

18-(1.4X1.25X2.4)=18-(1.4X3)=18-4.2=13.8

18-(1.4×1.25×2.4)
=18-(1.25×8×1.4×0.3)
=18-(10×1.4×0.3)
=18-(14×0.3)
=18-4.2
=13.8

18-(1.4*1.25*2.4)=18-(1.25+0.4*1.25)*(2+0.4)=18-(1.25+0.5)*(2+0.4)=18-1.75*(2+0.4)=18-3.5-0.7=13.8

18-(1.4×1.25×2.4)
=18-4.2
=13.8
\(^o^)/

18-(1.4×1.25×2.4)
=18-(1.4x1.25x3x0.8)
=18-1.4x3x1
=18-4.2
=13.8

=18-(1.75x2.4)
=18-4.2
=13.8

18-(1.4*1.25*2.4)
=18-[1.4*0.3*(1.25*8)]
=18-(4.2*1)
=18-4.2
= 13.8

18-(1.4×1.25×2.4)
=18-(1.25×8×1.4×0.3)
=18-(10×1.4×0.3)
=18-(14×0.3)
=18-4.2
=13.8
