Okay. I'm curious. What exactly is 'new math'? And how new is it? And what was old math? And why is new math not as good as old math? I seem to remember a PTA meeting in the mid 70's where my dad (who was a math major in college) stood up and had a heated argument with some guy about something. After the meeting, I asked my dad what that was about. He said he didn't want the school trying to teach new math. I nodded and said "Oh" in the way that kids do when they don't really understand something but want other to think they do. Just for reference, I'm no arithmetician, but I supposedly know my numbers up through differential equations.
