  1. 132 – {100 – [(78 – 73)^{2} : 5 + 9]}
    = 132 – { 100 – [ 5^{2} : 5 + 9]}
    = 132 – { 100 – [ 5 + 9]}
    = 132 – { 100 – 14 }
    = 132 – 100 + 14
    = 46
     

  2. 132 – {100 – [(78 – 73)^2 : 5 + 9]}
    = 132 – {100 – [5^2 : 5 + 9]}
    = 132 – {100 – [25 : 5 + 9]}
    = 132 – {100 – [5 + 9]}
    = 132 – {100 – 14}
    = 132 – 86
    = 46
