# Forget base-10!

We all know how to count with our fingers but unfortunately we stop only at $$10$$ .

but if we use the base-2 to count with our fingers we can reach a highest number.

Find the biggest number we count to using base-2.

PS: the way to count is the first finger is $$1$$ the second is $$2$$ so if we want to make a $$3$$ w raise up the first two fingers, and so on..
