777 9十111x37简便算法

777x9+111x37=111x7x9+111x37=111x63+111x37=111x(63+37)=111x100=11100

777x9十111x37=111X7X9+111X37=111X(7X9+37)=111X100=11100 希望对你有帮助,满意请及时采纳,你的采纳是我回答的动力!

37x111+777x9 =37x 111 + 7x111x9 =111x(37+63) =111x100 =11100

777=7x111 所以:原式=111x(7x9+37) =111x(63+37) =111x100 =11100

777*9 + 111*37= 111*7*9 + 111*37= 111*63 + 111*37= 111*100= 11100

原式=111*7*9+111*37=111*63+111*37=111*(63+37)=111*100=11100

=111x7x9+111x37=111x63+111x37=111x(63+37)=111x100=11100

777乘9+111乘37=111x7x9+111x37=111x63+111x37=111x(63+37)=111x100=11100

777*9+111*37=111*7*9+111*37=111*(63+37)=111*100=11100

=111*7*9+111*37=111*(63+37)=111*100=11100
