I have a number of roses for sale. The first buyer bought half of my roses then I gave him additional one for free. The second buyer bought half of the remaining roses then I gave him additional one also for free. The third buyer also bought half of the remaining roses then I gave him additional one also for free, this time all of my roses has been sold out.
How many roses do I have?

14, I believe....
14/2 = 7 - 1 = 6
6/2 = 3 - 1 = 2
2/1 = 1 - 1 = 0
14/2 = 7 - 1 = 6
6/2 = 3 - 1 = 2
2/1 = 1 - 1 = 0

{[(x/2-1)/2]-1}/2-1 = 0
{[(x/2-1)/2]-1}/2 = 1
[(x/2-1)/2]-1 = 2
(x/2-1)/2 = 3
x/2-1 = 6
x/2 = 7
x = 14
But, of course, now I have 0 roses.

14 is the correct answer but.....the question should've been stated : How many roses did I have to start with?
