简便计算:111×63+777×91

简便计算:111×63+777×91
111×63+777×91
=111×7×9+777×91
=777×9+777×91
=777×(9+91)
=777×100
=77700

111×63+777×91=111×7×9+777×91=777×9+777×91=777×100=77700

111×63+777×91
=777×9+777×91
=777×(9+91)
=777×100
=77700

111×63+777×91=111×(63+637)=77700

111*63+111*7*91
=111*[63+637]
=111*700
=77700
