Try this-
Type one row of asterisks on a word processing document.
Count them.
Copy and paste until one full page of asterisks is achieved.
Using the number of asterisks on 1 page, calculate how many pages of asterisks you would have to type to show 5 billion of them.
Given that there are 500 sheets in one ream/package of paper, how many reams would be needed to print out 5 billion asterisks?
Given that there are 10 reams in one case of printer paper, how many cases of paper would be needed to print 5 billion asterisks?
WELL? HOW MANY??????????????
