40 : 4 + 54 : 6 + 7 × 8 =

= 10 + 54 : 6 + 7 × 8 =

= 10 + 9 + 7 × 8 =

= 10 + 9 + 56 =

= 19 + 56 = 75

959 - 5 × (60 : 3 + 7 × 24) =

= 959 - 5 × (20 + 7 × 24) =

= 959 - 5 × (20 + 168) =

= 959 - 5 × 188 =

= 959 - 940 = 19

42 × 2 - 44 : 2 - (6 × 4 - 3 × 2) =

= 42 × 2 - 44 : 2 - (24 - 3 × 2) =

= 42 × 2 - 44 : 2 - (24 - 6) =

= 42 × 2 - 44 : 2 - 18 =

= 84 - 44 : 2 - 18 =

= 84 - 22 - 18 =

= 62 - 18 = 44
