There are two rubber ducks on the counter. If you take two of them, how many rubber ducks do you have?

+865 Uhh... if you take 2 and there are 2 on the counter.
You have 0 left?
+1252 The question is how many do YOU have, not how many are left.
So two, since you took two.
+37146 Depends on how many you HAD before you stole 2 more from the counter !
