777×4+111×73-111怎么简便计算？

Answer 1

用乘法分配律:
777x4+111x73-111
=111x7x4+111x73-111
=111x28+111x73-111
=111x（28+73-1）
=111x100
=11100

Answer 2

777×4+111×73-111
=111×28+111×72
=111×（28+72）
=111×100
=11100

Answer 3

777x4+111x73-111
＝111x7x4+111x73-111x1
＝111（4x7+73-1）
＝111x100
＝11100

Answer 4

777×4+111×73－111
=7×111×4+111×73－111
=111×（7×4+73－1）
=111×100
=11100

Answer 5

777x4+111x73-111
=（111x7x4）+111x73-111x1
=111x28+111x73-111x1
=111x（28+73-1）
=111x（101-1）
=111x100
=11100
