- Do exercise 1.12, p. 18.
- Exercise 1.x1: Write a Scheme expression with no multidigit numbers in it that has 170 as its value.
- Do exercise 1.14, p. 19.
- Do exercise 1.15, p. 19.
- Do exercise 1.16, p. 19.
- Exercise 2.x1: The following definition makes use of
`quotient`

, which is a procedure built in to Scheme. The`quotient`

procedure divides one integer by another, but returns only the quotient, ignoring the remainder. For example,`(quotient 2718 10)`

evaluates to 271, because 271 is the number of times 10 goes into 2718. Your task is to list the steps in evaluating`(round-down 2718)`

, using the same format as at the bottom of page 26 in your textbook.(define round-down (lambda (n) (if (< n 10) n (* (round-down (quotient n 10)) 10))))
