I could not precisely understand the definition. When you apply the Bead rule to a=《《1,1》》, the resulting value &a will be a_0+1, i.e. 《1,1》+1. On the other hand, there is not definition of "the addition of an array and a natural number". I guess that you meant &a = &a_0+1 or something like that in the case a is not an array of natural numbers.
