  65 - 24 = 66 - 16 = 77 - 34 = 93 - 61 =

  85 - 25 = 5 5- 14 = 67 - 56 = 56 - 9 =

  42 + 9= 43 + 3 = 48 + 4 = 25 + 3 =

  35 + 4= 23 + 9 = 3×5 = 9 + 26 =

  25 + 5 = 24 + 7 = 24 + 6 = 38 + 7 =

  2×1= 53 - 20 = 45 - 20 = 43 - 21 =

  59 - 44 = 3×3 = 36 - 14 = 87 - 77 =

  36 + 43 = 25 + 55 = 24 + 16 = 5×2=

  34 + 82= 49 + 5 = 2×2 = 2×2 =

  46 - 8 = 34 - 5 = 83 - 6 = 45 - 23 =

  45 - 12 = 63 - 12 = 53 - 40 = 89 - 85 =

  98 - 50 = 78 - 23 = 56 - 24 = 69 - 5 8 =

  45 + 25 = 12 + 46 = 47 + 13 = 25 + 14 =

  18 + 20 = 3 6 + 21 = 4×5 = 27 + 12 =

  24 + 25 = 35 + 12 = 4 0 + 58 = 26 + 13 =

  1×5 = 72 - 22 = 45 - 13 = 36 - 27 =

  14 - 13 = 58 - 47 = 2×3= 15 - 9 =

  60 + 32 = 31 + 12 = 34 + 25 = 17 + 12 =
