k mình nha...^_^...kb nữa... thanks

-29.(85-47) - 85.(47-29)

= -29.85 + 29.47 - 85.47 + 85.29

= ( -29.85 + 85.29) + 29.47-85.47

= 0 + 47.(29-85)

= 47.(-56)

= -2632

- 29 . ( 85 - 47 )  -  85 . ( 47 - 29 )

= - 29 . 85 + 29 . 47 - 85 . 47 + 85 . 29

= ( - 29 . 85 + 85 . 29 ) + 29 . 47 - 85 . 47
