A Year of Nights of Wondering – IV

I was discussing the difference between the phrase “the square of z” and “the square root of z” in class yesterday.  I asked, “So what does the square root of z mean?”  One of my students said that it means that the z is in the garage.  “Garage? What garage?”  She said that the front of the square root symbol, \sqrt{} looks like a garage door.  I guess it does.  So now I get to say that z is in the garage.  Kinda like Elvis is in the room.  What fun!
