Well, maybe the notion of neutral operand (not sure if it's the correct
ENglish term) would fit there: 0 for + and -, 1 for * and /:

(js:js* '(- 4)) ==> "-4;"  ; 0-4
(js:js* '(+ 4)) ==> "4;"   ; 0+4
(js:js* '(/ 4)) ==> "1/4;" ; 1/4
(js:js* '(* 4)) ==> "4;"   ; 1*4

I'll say special case either just '- or both '- and '/. If I'm not
mistaken, in the former, the / wil just have no sense for javascript.

Mathematically,
