Answer 1

thats to much math for me

Answer 2

I was with you all the way up to '7 billion people'

Answer 3

There are 31.556,926 seconds in a year, so doing a billion things at one per second takes about thirty years.  So your dollar bill task would take about 200 years.  Note that the US government spends a billion dollars every three hours.
