Get that math out of my yard!

I'm doing chapter two of my math for poets book, all about weighted voting and how it works. It's weird, there will be these nice descriptions of how things work and why and why the president really doesn't have any more power when he vetoes than does anyone else who is voting on the issue and then all of a sudden there will be some math like this:

[q:W1,W2, ... , Wn]

What the hell? Who put this math in my math?

Anyway, don't expect too many posts from me until I finish this course. I'm supposed to do FIFTEEN hours of math every week. I didn't know I had fifteen hours a week to spare...
