The link presented earlier in this thread,


starts off with:

   A.2.7 Operator Input Forms

   Characters that are not letters, letter-like forms or structural
   elements are treated by Mathematica as operators.

Since letters are not numbers (i.e., numerals); the formal documentation 
on "letter-like forms" makes no mention of numbers; and I don't think 
that numbers are "structural elements" (didn't look that one up, 
actually), does this mean that Mathematica treats "3" as an operator, so 
that inputs like

   a 3 b    or    a3b

are taken as some kind of operator connecting a and b, or operating on b?
