Homework, Oh boy!

So, your homework is only 9 questions and you can download it and show your work directly on it and then submit it on Google Classroom. No need to use your phone to take a lousy picture of it which will probably not get you full credit. Full credit goes to those students who show all their work, and submit it correctly and on time.
