1.35×2.5+26.5×0.25 (简便计算)
1.35×2.5+26.5×0.25 (简便计算)

1.35×2.5+26.5×0.25 (简便计算)
1.35×2.5+26.5×0.25
=1.35×2.5+2.65×2.5
=(1.35+2.65)×2.5
=4×2.5
=10

1.35*2.5+26.5*0.25
=1.35*2.5+2.65*2.5
=2.5*(1.35+2.65)
=2.5*4
=10

1.35×2.5+26.5×0.25
=13.5×0.25﹢26.5×0.25
=0.25×﹙13.5+26.5﹚
=0.25×40
=10

1.35×2.5+26.5×0.25
=13.5×0.25+26.5×0.25
=0.25×(13.5+26.5)
=0.25×40
=10
