I just have to put this in here! In a comic strip titled "FOXTROT" drawn by Bill Amend, today (I'm reading it in the Washington Post), we have a teenage girl writing on a homework paper: "First, I looked in the back of the book, but it wasn't an odd numbered problem. Then I asked my little brother, but he wanted me to pay him $5. Finally, I found it on the internet with Google." Why is she writing that? As she tells her little brother: "My math teacher wants us to show how we get our answers."!!
