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

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.
