for(i = 0; i < operandArr.length; i ++ )
{
metaOpArr[i] = operandArr[i].split("").map(Number).reverse();
}
If operandArr=[12,5,28] will not metaOpAr[8] contain 2,1 and be an array in itself?

metaOpArr[0] contain 2,1 and be an array in itself?

No, because numbers don't have a split() method. If operandArr is ["12",
"5", "28"] instead, then metaOpArr[0] is indeed the array [2, 1].
I don't know it that's good or bad, because you forgot to tell us what
your trouble with arrays is, and what you want the code to do.
