This isn’t completely uncommon for math-y people, and those I’ve known have shown their pre-9th grade background through their accomplishments in high school math competitions or classes. I love @skieurope’s idea of using it in an essay, although I’d recommend against pigeonholing yourself into a “math only” person in your main essay. Great topic for supplemental essay–eg. Brown has a supplement with the question “what brings you joy?”
