128.(278-302)+278.(302-128) =128.278-128.302+278.302-278.128 =128.(278-278)+302.(-128+278) =128.0+302.150 =45300 Bình luận
128.(278-302)+278.(302-128) =128.278-128.302+278.302-278.128 =(128.278-128.302-278.128)+278.302 =128.(278-302-278)+278.302 =128.(-302)+278.302 =302.(278-128) =302.150 =45300. Bình luận
128.(278-302)+278.(302-128)
=128.278-128.302+278.302-278.128
=128.(278-278)+302.(-128+278)
=128.0+302.150
=45300
128.(278-302)+278.(302-128)
=128.278-128.302+278.302-278.128
=(128.278-128.302-278.128)+278.302
=128.(278-302-278)+278.302
=128.(-302)+278.302
