My copy of K&R 1st edition has nothing remotely resembling that.

I think someone here already mentioned that the English version
looks different compared to the translation I've in my bookshelf.
(So I am not sure what your post is actually intending.[*])

(But that's anyway unimportant to the point I made; that you can
define semantical information like the precedence separately or
by syntax.[**])

PS: FYI; Some of your posts, James, arrive also in my mailbox.

[*] I've put (if you're interested) a scan of that page uploaded
here: http://volatile.gridbug.de/KR_syntax-rotated90.pdf
(But similar syntaxes for expressions can be found also in other
programming languages' contexts; see below.)

[**] There's various levels of abstraction possible. For example
- describe expressions in- or semi-formally (e.g. in Bolsky/Korn)
- describe them without precedence semantics ("K&R DE version")
- reflect operator precedence in syntax (quite typical)
- allow extensions/change of operators and precedence (Algol 68)
(Sometimes there's no clear line; e.g. part of the definitions
for expressions in Bolsky/Korn are like in the "K&R DE version",
and the precedence is defined by the order they are listed.)
