    a) `58.75+58.50-58.25`

    `= 58.(75+50-25)`

    `= 58.100`

    `= 5800`

    b) `27.39+27.63-2.27`

    `= 27.(39+63-2)`

    `= 27.100`

    `= 2700`

    c) `128.46+128.32+ 28.22`

    `= 128.(46+32+22)`

    `= 128.100`

    `= 12800`

    d) `66.25+5.66+66.14+33.66`

    `= 66.(25+5+14+33)`

    `= 66.77`

    `= 5082`

    e) `12.35+35.182–35.94`

    `= 35.(12+182-94)`

    `= 35.100`

    `= 3500`
