0.999*1.3-0.111*1.7怎么算?

0.999*1.3-0.111*1.7怎么算?
0.999*1.3-0.111*1.7怎么算?

0.999*1.3-0.111*1.7怎么算?
0.999*1.3-0.111*1.7
=0.111*11.7-0.111-1.7
=0.111*10
=1.11

1X1.3-0.001X1.3-(0.111X2-0.111X0.3)=1.3-0.0013-(0.222-0.0333)=1.11

0.999*1.3-0.111*1.7
=0.111*9*1.3-0.111*1.7
=0.111X(9X1.3-1.7)
=0.111*10
=1.11

0.999*1.3-0.111*1.7
=0.111*1.3*9-0.111*1.7
=0.111*(11.7-1.7)
0.111*10
=1.11
