my grandaughter is doing array dot to dot sample make as manydifferent arrays as possible number 5 how would i go about doing a array with dots please, desperate in need to keep up with my grandaughters homework.

What grade does your granddaughter go to, grade school, highschool, or college. They all do arrays in different ways.
For grade school, an array is probably a rectangular arrangement of objects, a 3x4

or a 4x6

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