I do not think youngsters would have any problem with +/ or any other computing mechanism unless too much time is spent going over theory and thoughts and not enough time is spent going over practical aspects.
For that matter, I think youngsters can understand quantum mechanics if it's presented to them the right way, and if we do not ask too much from them. Just keep it practical (for example: talk about the rainbow effect of thin oil on water - and show it to them - and leave development of more cerebral topics for later).
