    What grade does your grand-daughter go to, grade school, high-school, or college. They all do arrays in different ways.
    For grade school, an array is probably a rectangular arrangement of objects, a 3x4
    oooo
    oooo
    oooo
    or a 4x6
    xxxxxx
    xxxxxx
    xxxxxx
    xxxxxx

    In college, arrays are like matrices, and there are dot product of vectors.
    It would be nice if your grand-daughter describes the problem, or post an example problem so that we can better understand the question.
