888x(乘号)7+111x44怎么简便运算

888x(乘号)7+111x44怎么简便运算
888x7+111x44
=111x8x7+111x44
=111x56+111x44
=111x(56+44)
=111x100
=11100

111*8*7+111*44
=111*56+111*44
=111*(56+44)
=111*100
=11100

=111x8x7+111x44
=111x(8x7+44)
=111x100
=11100

=111*8*7+111*44
=111*(56+44)
=111*100
=11100

888x7+111x44
=111x8x7+111x44
=111x56+111x44
=111x(56+44)
=111x100
=11100

这样写:111*8*7+111*44=111*56+111*44=111*(56+44)=111*100=11100(乘法分配律)
