LISP – (LISt Processing) 1. Parenthesized prefix notation: (+ 2 4) 2. Expressions can be nested: (- (+ 2 3 4 5) (* 2 5)) 3. Evaluation rule: apply function to value of arguments. 4. Symbolic computation: other types Primitive: numbers, characters, strings, symbols. Compound: lists. (append '(a b) '(c d)) --> (a b c d) Quote: block the evaluation of the following expression. '(a b) --> (a b) (a b) --> error: a undefined function. 5. Self-evaluating types: numbers, characters, strings. 6. Symbols as variables - not case sensitive.
