0.011

上面都有问题

1.1×1.1×1.1-1.1×1.1-0.11
=1.1×1.1×(1.1-1)-1.1×0.1
==1.1×1.1×0.1-1.1×0.1
=1.1×0.1×(1.1-1)
=1.1×0.01
=0.011

回答2:

1.1*1.1(1.1-1)-0.11
=0.11*1.1-0.11
=0,11*(1.1-1)
=0.11*0.1
=0.011

回答3:

1.1×1.1×1.1-1.1×1.1-0.11
=1.1×1.1×(1.1-1)-1.1×0.1
==1.1×1.1×0.1-1.1×0.1
=1.1×0.1×(1.1-0.1)
=0.011

回答4:

原式=(1.1×1.1)(1.1-1)-0.1×1.1
=0.1×1.1(1.1-1)
=0.11×0.1
=0.011

我试试:
原式=1.1*1.1*(1.1-1)-0.11
=(1.1-1)*0.11
=0.011
