I know you've been working hard this week and reading a lot so I'll keep this brief. Here's one final PSSA style question:
Why in Mathopolis would you get one of these?
a. You need a clock.
b. You've got mad math skills and you want to practice them.
c. You like Nines.
d. You are so cool your friends need to wear a sweater when they hang out with you.
This one is from the Triple Nine Society (if you search for that you can find out more info.)
Stay radical!
