# How many cakes?

Thu 23 Mar, 2006 02:26 pm
You are on your way to visit gramma, who lives at the end of the valley, its her birthday and you want to give her the cakes you made.

Between your house and her house, you have to cross 7 bridges, and there is a troll under each bridge.

Each troll insists you pay a troll toll. Before you can cross their bridge you have to give them half of your cakes,,but as they are kind trolls they each give you back a single cake.

How many cakes do you have to leave home with to make sure you arrive at grandmas house with exactly 2 cakes?
