You can do something like this:

: +  32 WORD  NUMBER + ;

This defines plus to be a word that reads in the following word,
converts it to a number on the stack, then adds that to the number
previously put there.  This is almost identical to a similar word
defined on page 277 of Brodie's _Starting Forth_.

A similar idea is used with almost all text-oriented operations in
Forth.  Although Forth uses postfix notation for numbers, for text it
(of practical necessity) reverts to prefix or infix.
