Since we can count to “10” (12) on one hand, we can use the other hand to count sets of “10”, bringing us up to “100” (144). With decimal, we’re stuck at 20, and that’s only if we’re wearing sandals.
If you’re pointing to the last phalange on both hands, that would be “110” (156) though wouldn’t it. Since it would be “10” x “10” + “10”.
We could also use this method to count to 100 in base-10 using only the first 10 phalanges of the hand.
That’s because you’re working in base 10. That person wants to covert to base 12.
In which case teaching kids to count becomes more difficult because we have ten fingers
Unless you use your thumb to point to the phalanges of each finger.
Ok that’s me convinced. I’m on board train dozenal!

Yeah that’s true.
