If you take 2 apples out of a basket containing 6 apples how many apples do you have?
it depends on whether there are 6 apples in the basket before or after you took the two out... and whether the the apples in the basket are yours or not to begin with...possible answers:2 (if you count the apples that you have at hand)4 (if you are counting the apples in the basket only)6 (if there are 6 before you take two out and all the apples in the problem as yours)8 (if there are 6 apples in the basket after you took the two out in which case there are 8 apples in total)
