Nine cents is definitely worthy of 50 claps!! The power of doubling...think about nine cents doubling for just ten days. That comes to $46...now do it for another ten days. That becomes $47, 185.92. Now work out how to do this.

I used to do it with my young students...helping at home starting for free, and doubling every night. They would get their parents to sign a contract to pay at the end of the month. Can you imagine the excitement?
