    Simplifying

    How can I simplify the following...
    14-9/4^2- 2^3
    The test puts it exactly in this format I don't understand if it's to confuse me? Or I simply don't know my math very well.

    Here I will use PEMDAS.

    My solution
    14-\frac{9}{16}-8

    \frac{14}{1}-\frac{9}{16}-8

    = \frac{224}{16}-\frac{9}{16}-8

    = \frac{215}{16}-\frac{128}{16}

    = \frac{87}{16}
    or
    = 5\frac{7}{16}

    This is correct.

    Edit: A simpler way is

    14-\frac{9}{16}-8=6-\frac{9}{16}=5+\frac{16}{16}-\frac{9}{16}=5\frac{7}{16}

    Weird my sample test is not providing me the right answer.
    Probably the test did not include the "NONE OF THESE" answer.
