1.1111×1.9999-0.1111×0.9999
怎么简便算啊
1.1111×1.9999-0.1111×0.9999怎么简便算啊
1.1111×1.9999-0.1111×0.9999
=（1+0.1111）×（1+0.9999）-0.1111×0.9999
=1+0.9999+0.1111+0.1111×0.9999-0.1111×0.9999
=1+1.111
=2.111
1.1111×1.9999-0.1111×0.9999=(1+0.1111)*(1+0.9999)-0.1111×0.9999=1+0.1111+0.9999+0.1111*0.9999-0.1111*0.9999=1+0.1111+0.9999=2.111
更简单的使用计算器
1.1111×1.9999-0.1111×0.9999
=(1+0.1111)(1+0.9999)-0.1111*0.9999
=1+0.9999+0.1111+0.1111*0.9999-0.1111*0.9999
=1+0.9999+0.1111
=1+1-0.0001+0.1111
=2+0.1110
=2.111
