before 2009, I never had heard about the word 'trillion'
In France and Italy, some scientists then began using billion to mean 10 square 9, trillion to mean 10 square 12, etc. This usage became more common with time, it was first used in 1600 bro. Before people used to refer it as millions million. History is crazy but a fun thing to study, the world needs to learn from its mistakes
Unfortunately most people can't remember much other than the last snapchat they got...
Seriously I was sitting at a baseball game and there were a bunch of 20-somethings sitting in front of me. The entire game they sat there texting, facebooking, snapchatting, etc. THE WHOLE 9 innings! Dont expect them to learn from history, let alone look up from their phones...
