12 is easy: you have 3 phalanges on each of your 4 fingers, leaving your thumb as a placeholder to count to 12. How do you count to 31?
I’m aware of the abacus hand method, but sadly it wasn’t taught when I was a kid in school, when my brain was still elastic. I’d probably have enjoyed math more if they had. Is counting to 31 part of that method?
