    36 : 3^2 – 2 . 5^3
    = 36 : 9 – 2 . 125
    = 4 – 250
    = – 246
    _______________________
    7^3 . 98 – 7^3 . 46 – 52 . 143
    = 7^3 . (98 – 46) – 52 . 143
    = 343 . 52 – 52 . 143
    = 52 . (343 – 143)
    = 52 . 200
    = 10400
    _______________________
    29 . 87 – 29 . 23 – 29 . 74
    = 29 . (87 – 23 – 74)
    = 29 . (-10)
    = -290
    _______________________
    [50 – 30 – (6 – 2)^2]
    = [20 – 4^2]
    = [20 – 16]
    = 4
