This is a simple set of exercises to give everyone some practice with the basics of Racket expressions and the DrRacket development environment. These are crucial building blocks that will form the foundation of everything that will happen in this course, so start early and ask lots of questions.

You should have at least one check-expect expression for each exercise.

See the Canvas site for examples of solving similar exercises, and for info on how to submit your work.

Exercises

Do these exercises from Chapter 1 of the course text:

Exercise 3 (3 pts)
Exercise 4 (3 pts)
Exercise 8 (5 pts)
- In exercise 8 it’s fine to implement just tall and wide, and not square.

In all three of these the essential idea is to define named expressions, like x and y defined by

(define x 7)
(define y 5)

and then use those named expressions to create other more more complex expressions like

(* x y)

that have the desired properties. The expression (* x y) above, for example, would be a great solution if the task was to write an expression that computes the product of x and y.
