{empty} simply means N/A, non available. From some point of view it
is equivalent to "not defined" and, consequently, any addition to a
not defined quantity will be N/A too, ie {empty}.
On the other side, the neutral element of the addition is 0 and one
could expect X+{empty}=X, since X is not empty, it exists and it is
irrational to be disappeared.
Two different points and some priorities in addition concept...
If you have 4 boxes and you add the apples, you would probably say
30+50+20+0 if the last box was empty. Would you say "I can not sum
the oranges, because the last box is empty" ? Probably not...
The common sense, IMO, would count 100 oranges.
