;; Exercise 1.1.  Below is a sequence of expressions. What is the
;; result printed by the interpreter in response to each expression?
;; Assume that the sequence is to be evaluated in the order in which
;; it is presented.

;; 10
;; => 10

;; (+ 5 3 4)
;; => 12

;; (- 9 1)
;; => 8

;; (/ 6 2)
;; => 3

;; (+ (* 2 4) (- 4 6))
;; => 6

;; (define a 3)
;; (define b (+ a 1))

;; (+ a b (* a b))
;; => 19

;; (= a b)
;; => #f

;; (if (and (> b a) (< b (* a b)))
;;     b
;;     a)
;; => 4

;; (cond ((= a 4) 6)
;;       ((= b 4) (+ 6 7 a))
;;       (else 25))
;; => 16

;; (+ 2 (if (> b a) b a))
;; => 6

;; (* (cond ((> a b) a)
;;          ((< a b) b)
;;          (else -1))
;;    (+ a 1))
;; => 16
