I think it has to do with her views on math being related to her other creative interests - saying you could compare a mathematical theorem to a poem, for example.

Also, where she talks about how she sits and works at a computer but that's not where the real work happens. The real work can happen when she's doing something that allows her mind to wander, like cleaning, but her mind is still working in the background.

Sounds like a creative process to me.
