    `(-1/4) .(-2/13) -7/24 . (-2/13)`

    `=(-2/13). (-1/4-7/24)`

    `=(-2/13).{-13}/{24}`

    `=1/2`

    `(-1/27)x3/7+ 5/3 x (-3/7)`

    `=-1/{63}+{-5}/7`

    `=-{46}/{63}`

    `(-1/5 +3/7) : 2/11 + (-4/5 +4/7 ) : 2/11`

    `=8/{35}.{11}/2+{-8}/{25}.{11}/2`

    `=({8}/{35} -{-8}/{25}).{11}/2`

    `=0.{11}/2`

    `=0`

    `3 x (-2/3)^3 + 3,15 -13/3 : 3/2`

    `=3 x(-8/27) + 63/20 -13/3 .2/3`

    `=-8/9+ 63/20 – 26/9`

    `={-113}/{180}`
