    -\frac{1}{3}-\left(-\frac{7}{8}\right)+\frac{11}{12}

    Remove the parenthesis:
    -\frac{1}{3}+\frac{7}{8}+\frac{11}{12}

    Find the lowest common denominator for the first two: -\frac{8}{24}+\frac{21}{24}+\frac{11}{12}

    Add: \frac{-8+21}{24}+\frac{11}{12}

    Add: \frac{13}{24}+\frac{11}{12}

    Find the lcm: \frac{13}{24}+\frac{22}{24}

    Add: \frac{13+22}{24}

    Add: \frac{35}{24}
