prefix notation
(language)(Or "prefix syntax") One of the possible orderings
of functions and operands: in prefix notation the function
precedes all its operands. For example, what may normally be
written as "1+2" becomes "(+ 1 2)". A few languages (e.g.,
lisp) have strictly prefix syntax, many more employ prefix
notation in combination with infix notation.
