For example, square roots were never a problem for me.
  By the time we were on square roots, I already knew to draw a
  square in basic, I'd have to do something like:

  For i=1 to 40
  for j = 1 to 40
  DRAW (i,j,3)
  next j
  next i

  Something like that. [I don't remember what the draw command
  was]

  So that's how I made a square.

  So when square roots came out for me in 7th grade, I was like,
  "Oh, Just REM out the j. What's the i?"

  and that was it. Nobody knew what the hell I was talking about
  but this was back in 1984 I think.
