To do math, I may literally visualize the numbers in my head, like an extra piece of paper I can manipulate numbers on, but it's not literal paper so it doesn't have to conform to annoying IRL properties like fixed transparency and permanent ink that can't be slid around.

It gets difficult to do more than simple calculus and algebra problems purely in my head, so I start offloading parts of my virtual workspace to a meatspace page.
