可以进行两次变化
44×21+16×56+56×5
=44×21+(16+5)×56
=44×21+21×56
=(44+56)×21
=100×21
=2100
44×21+16×56+56×5能简算简算吗?
44×21+16×56+56×5
=44x21+56x(16+5)
=44x21+56x21
=21x(44+56)
=2100
解:44×21+56×(16+5)
=44×21+56×21
=(44+56)×21
=100×21
=2100望采纳
44×21+16×56+56×5=44×21+56×(16+5)=44×21+56×21=21×(44+56)=21×100=2100
44×21+16×56+56×5=44×21+56×(16+5)=21×(44+56)=21×100=2100
