Where, exactly, is the intersection between Math and Patterns?

I enjoy math, but I’m not any good at it – my attention tends to throw its hands up in disgust when I actually make the ol’ brain work hard. I enjoy patterns, too, and those hold my attention longer so I’m pretty good with them. And I know that math and patterns are sort of hand-in-glove.

So I was wondering if there were a way to leverage my mad pattern skillz for mathematical purposes – or really, anything more interesting than laying tile. Which I’m pretty good at.
