1x1.1x1.1-1.1x1.1-0.11怎样简便计算
1x1.1x1.1-1.1x1.1-0.11怎样简便计算

1x1.1x1.1-1.1x1.1-0.11怎样简便计算
1.1²*1.1-1.1²-1.1*0.1
=1.1²*(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*0.1*0.1
=1.1*0.01
=0.011

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