Adding numbers by binary balls

Hi, my college has just purchased some TTs and I was wondering if it is possible to add 2 numbers represented by binary (1 - blue marble 0 - red marble) on both sides. The answer appears as binary on one side at the bottom.

TT can’t distinguish the two types of ball, so it would not be possible to work with two arbitrary patterns of red/blue balls.

It would be possible to create a limited binary adder where the input numbers were set up with ‘bits’ (i.e. the initial positions of the bi-state pieces). The output could be represented by other bits, or, possibly, by a pattern of red/blue balls per your original idea.

Richard, thank you for your reply. Will have a play with your idea of a binary adder.
