777*9+111*37的简便运算
还有:5.6*69.32+138.64*0.05+693.2*0.43

777*9+111*37的简便运算还有:5.6*69.32+138.64*0.05+693.2*0.43
777*9+111*37
7*111*9+111*37
=63*111+37*111
=(63+37)*111
=11100

777*9+111*37
=111×7×9+111×37
=111×73+111×37
=111×(63+37)
=111×100
=11100
ok

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

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

777*9+111*37
=111×7×9+111×37
=111×73+111×37
=111×(63+37)
=111×100
=11100

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

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