- I don't understand hat notation?

I'm new to classical mechanics.

I've done enough work with vectors to get the basics.

But, I'm having trouble understanding the notation on this MIT presentation I found on circular motion: http://web.mit.edu/8.01t/www/materials/Presentations/Presentation_W04D1.pdf

On slide 23, for example, I don't understand how they keep multiplying (it seems) with r-hat (is that how you say it?).

I don't quite get how to translate the position equation on the top of the slide either.

I'll be happy with either an explanation or a link to good resources to read on the topic.

Thanks in advance!
