list - What's the formal name for this Syntax? -

-

sometimes in scheme, have functions take arguments this

add 3 4

what call kind of "list" it's elements a1 a2 a3 ? don't think can call list because lists contained in parenthesis , elements comma-seperated.

polish notation, known prefix notation, form of notation logic, arithmetic, , algebra. distinguishing feature places operators left of operands. if arity of operators fixed, result syntax lacking parentheses or other brackets, can still parsed without ambiguity.

add operator , right part operands.

the arity of operators isn't fixed lisp uses parens in it's syntax group expressions.
