11 + 67 x 24 + 12 + 55 - 24

= 11 + 55  + 67 x 24 - 24 + 12

= 66 + 24 x (67 - 1) + 12

= 66 + 24 x 66 + 12

= 66 x (24 + 1) + 12

= 66 x 25 + 12 

= 1650 + 12

= 1662

11 + 67 x 24 + 12 + 55 - 24

= 11 + 55 + 24 x ( 67 - 1) + 12

= 66 + 24 x 66 + 12

= 66 x ( 1 + 24 ) + 12

= 66 x 25 + 12

= 1650 + 12

= 1662

=122 nha bạn

122 kmik nha

ta có: 2005 + 53-54-55+56-57-58-59+60+61-62-63+64+65-66-67+68+69

      = 2005+(53-54-55+56)+(57-58-59+60)+(61-62-63+64)+(65-66-67+68)+69

      = 2005+0+0+0+0+69

      = 2005+69

      = 2074
