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.
