Adding values in an array

I am relatively new at working with arrays.  I want to add the values in one array to the values in a second array.  Something like this

Dim array1() as double
Dim array2() as Double
Dim array3() as double

array1(0) = 2
array1(1) = 5

array2(0) = 1
array2(1) = 6

this is where the line I don't know how to write would go.

If I were to debug.print array3() I want to see the following

Thanks very much in advance.

Something like:
Dim i As Long
For i = LBound(array1) To UBound(array1)
    array3(i) = array1(i) + array2(i)
    Debug.Print "array3(" & i & ") = " & array3(i)
Next i

This works fine for me as well also:
Dim array1(0 To 100) As Double
Dim array2(0 To 100) As Double
Dim array3(0 To 100) As Double

array1(0) = 2
array1(1) = 5

array2(0) = 1
array2(1) = 6

array3(0) = array1(0) + array2(0)
array3(1) = array1(1) + array2(1)

Debug.Print array3(0) & vbCrLf & array3(1)

If upper bound for first array differs from the second:

Yeah...I put absolutely no error checking in my snippet; just assumed that all arrays were the same size and had the same lower/upper/bounds.

And now you run into the age old problem of storing derivable data.  There you are with a1, a2, and a3.  Someone changes a value in a1 or a2, but does not update a3 which is the sum - now what?  You have to make sure every time you view the contents of a3, it is in fact re-created.
