It is the first definition I've seen of the Fibonacci series which allows an
explicit verb to be translated into a tacit expression.
f=: 13 :'% 1 +. (+%)/\ y $ 1x'
f 7
1 1 2 3 5 8 135
f
[: % 1 +. [: (+ %)/\ 1x $~ ]
5!:4 <'f'
5!:4 <'f'
-- [:
+- %
│ -- 1
--+ +- +.
│ │ -- [:
L----+ │ -- +
│ +- \ --- / -----+- %
L----+
│ -- 1x
L-----+- ~ --- $
L- ]
Thus I would think it would be the way I would introduce the seroes to a
high school class
which was studying J.

It also can help to think about this if you realize that adjacent numbers
in the fibonacci sequence are relatively prime.
