Sacrifice a few extra bits and you can do floating point arithmetic on your fingers too

Jokes on you, fingers are tri-state (fully extended, fully closed, bent at middle knuckle) not binary, so I can count to 59049.

Someone with better finger control should be able to treat them as quad-state, granting the ability to count to 1048576 by bending just the outer knuckle.

I like this idea in theory, but some combinations of fingers are very awkward to extend without the others, and one particular combination is very rude.

I’ve tried this a few times and my fingers always get really Fucking confused after about four bits.

I can't imagine a scenario when you need to be able to do BOTH positive and negative numbers at the same time 😂

If we figure out a clever trick with phalanges we can go even further
