This proves it, I've lost much of my mathematical knowledge. I'd have to sit down with these for a while to get any of them.

Thanks to my studying ahead of time, I completed them in about 30 minutes. I still had lots of time left on the 1 hour clock. I'm starting to like being able to understand this stuff. Weird.

I honestly think I'd do OK with a bit of review. I've got ideas about most of 'em but not enough time to sit and attempt them for kicks.

Understood! The fact that the questions kicked some cobwebs always works for me!

The answers are:

1. I don't know
2. I don't know
3. I don't know
4. I don't know
5. I don't know

I can definitely say that all five of these answers are correct, and I should therefore receive full credit.

I'll ask my teacher. *giggle*

Eek, I missed #5.

Never mind. Just hand me that dunce cap; I can put myself in the corner. :)

After doing so well, maybe you'll enjoy this article about a self-proclaimed "math moron"'s attempts to learn enough math to help her daughter with her 6th grade homework.

OUCH! But this also drives home the fact that Santorum's idea that ALL children should be home schooled is BS. Can you imagine this parent being in charge of teaching the kids math???
