Pretty interesting. I've seen counting with using your fingers as binary digits before, which will let you count up to 512, but this being usable for math is really cool.

You can get to 1023 with binary fingers, assuming you have all your fingers.

Wow. I like that a lot. Have you done that or is this just a thought?

Ive tried but I don't really have a use case in my day to day life beyond counting to 30 after that I'd rather keep paper records so I don't lose count.

Anyways, here the Wikipedia article about it.
