小学五年级的简便运算~~

55×10.43+104.3×4.4+104.3×0.1
=55×10.43+10.43×44+10.43×1
=(55+44+1)*10.43
=100*10.43
=1043

很简单

：：

=5.5×104.3+104.3×4.4+104.3×0.1
=(5.5+4.4+0.1)×104.3
=10×104.3
=1043

提出104.5
得 =104.5(55*0.1+4.4+0.1)
=104.5*10
=1045

答案是1043,至于过程,1,2楼的都说了,我也没必要随声附和

55×10.43+104.3×4.4+104.3×0.1
=104.3×(0.1+4.4+5.5)
=104.3×(4.5+5.5)
=104.3×10
=1043

=55*10.43+10.43*44+10.43*1
=(55+44+1)*10.43
=100*10.43
=1043
