Procedure | Result | |
(define a 1) | Defines the symbol a as value, where value is a literal, expression, or symbol | memory slot associated with symbol a now contains a base-2 representation of the number 1. |
(define b -3) | Defines the symbol a as value, where value is a literal, expression, or symbol | memory slot associated with symbol a now contains a base-2 representation of the number -3. |
(define c 2) | Defines the symbol a as value, where value is a literal, expression, or symbol | memory slot associated with symbol a now contains a base-2 representation of the number 2. |
(* b b) | Racket tries to interpret the token after a left paren as an operator/procedure/function/{verb} | 9 |
(* 4 a c) | Racket tries to interpret the token after a left paren as an operator/procedure/function/{verb} | 8 |
(- (* b b) (* 4 a c)) | Racket tries to interpret the token after a left paren as an operator/procedure/function/{verb} | 1 |
