    `7/12+1/4-5/6`

    `=7/12+3/12-10/12`

    `=10/12-10/12`

    `=0`

    `11/4+7/11+1/4+8 5/6`

    `=11/4+1/4+7/11+ 8 5/6`

    `=3 7/11+8 5/6`

    `=(3+8)+(7/11+5/6)`

    `=11+(42/66+55/66)`

    `=11 97/66`

    `3/5-8/5:(5,25+756)`

    `=3/5-8/5:(5 1/4+756)`

    `=3/5-8/5:(5+756+1/4)`

    `=3/5-8/5:(761+1/4)`

    `=3/5-8/5:3045/4`

    `=3/5-8/5*4/3045`

    `=3/5-32/15525`

    `=9283/15225`
