New problem!
It's your grandma birth day, and you want to give her a tasty and creamy cake as her present, but she lives so far of your house. To go to her house, you've to walk for a road, and cross 7 bridges, but under each bridge, there is a troll, and to pass for the bridge you've to give half of your cakes. But isn't so bad, the troll are gentle, even when you give a half of your cakes, the troll give you one cake back, what a kind troll, isn't it?...whatever, how many cakes do you have to carry, to arrive at your grandma's house with exactly 2 cakes?
Asnwer on Friday!

2 cakes ;D
Independent of the number of bridges, if you have 2 cakes, you will give one cake and receive one cake back. then you have 2 cakes again! Easy, isn't it?
Yay, I agree with Ricardo :D
