i don t understand what you mean?
the right answer was 7 -5 .why?because is the person who have less (5) will give one for the person who have more (7) thhe he will have 4 and the another one will have 8,then the double. and if the person who have 7 give 1 orange to the person who have less(5),the they will have the same amount 6-6 .You get me now?
