In 2012, Andrew Hacker wrote an opinion piece in the New York Times Magazine suggesting that teaching algebra in high school was a waste of time. http://tinyurl.com/9yedr2j. I was asked to comment on Hacker's article by students in my Stanford Continuing Studies course "Mathematics: Making the Invisible Visible" on iTunes University http://tinyurl.com/b7mnu46. I did not mince my words. Hacker was displaying his ignorance of what algebra is.
