Leezone - Were those years spent doing calculus the FIRST four years of your life?
It's obvious from other threads that you can't even count to two (2-1=1 is a valid equation!), so these huge numbers you are dealing with are difficult to grasp once you run out of fingers and toes, aren't they?
Just keep it simple... bigger than a bread box? Smaller than your head?
You might get less easily confused..!
