              題目

              (1)( ) - 53 = 44

              (2)95 -( ) = 16

              (3)( )+ 61 = 77

              (4)( ) + 34 = 98

              (5)( )- 43 = 19

              (6)35 +( ) = 88

              (7)( ) + 17 = 81

              (8) ( )- 64 = 22

              (9)( ) - 20 = 8

              (10)( ) + 44 = 98

              (11)66 -( ) = 21

              (12) ( )+ 11 = 72

              (13)95 +( ) = 99

              (14)44 + ( )= 69

              (15)90 + ( )= 98

              答案

              (1)(97) - 53 = 44

              (2)95 -(79) = 16

              (3) (16)+ 61 = 77

              (4)(64) + 34 = 98

              (5) (62)- 43 = 19

              (6)35 +(53) = 88

              (7)(64) + 17 = 81

              (8) (86)- 64 = 22

              (9)(28) - 20 = 8

              (10)(54) + 44 = 98

              (11)66 -(45) = 21

              (12)(61)+ 11 = 72

              (13)95 +(4) = 99

              (14)44 + (25)= 69

              (15)90 + (8)= 98
