Note that when (+ 2 3) would yield 7 in Elisp, I would accept your "it's wrong" because there is a valid interpretation using Ferraris: (+ 2 3) should return the number of Ferraris of two sets of two and three Ferraris, and these are five Ferraris. But what calculation involving Ferraris would (*) correspond to? I don't see any interpretation of the formula that would apply to Ferraris, so it's not valid to say that a result of "one Ferrari" is wrong. What should that have calculated? Michael.
