  1. 24.57 +24.43
    = 24. (57+43)
    = 24 . 100
    = 2400
    5 . 22 – 18 : 3
    = 120 – 6
    = 114
    25 . 8 – 12.5 + 170 : 17 – 8
    = 200 – 60 + 10 – 8
    = 140 + 10 – 8
    = 150 – 8
    = 142
    18 : 3 + 182 + 3.(51 : 17)
    = 6 + 182 + 3. 3
    = 6 + 182 + 9
    = 188 + 9
    = 177
    12 : { 400 : [500 – (125 + 25 . 7)]}
    = 12 : { 400 : [500 – (125 + 175)]}
    = 12 : { 400 : [500 – 300]}
    = 12 : { 400 : 200}
    = 12 : 2
    = 6
