    2/5 . [(3/5)^2 : (-1/5)^2 – 7] . (-1000)^0 – ║-11/15║
    =2/5 . [9/25 : 1/25 – 7 ] . 1 – 11/15
    =2/5 . [9 – 7] – 11/15
    =2/5 . 2 – 11/15
    =4/5 – 11/15
    =1/15

    2/5 . [(3/5)^{2} : (-1/5)^{2} – 7] . (-1000)^{0} – |-11/15|
    = 2/5 . [9/25 : 1/25 – 7] . 1 – 11/15
    = 2/5 . [9 – 7] . 1 – 11/15
    = 2/5 . 2 . 1 – 11/15
    = 4/5 . 1 – 11/15
    = 4/5 – 11/15
    = 1/15
