Eight fingers and two thumbs imply decimal counting from one to ten?
Even for learning the numbers by counting with the fingers,
hexadecimal is more logical and efficient than decimal:
With the right hand it´s possible to count from 0 to F, by moving the thumb to the finger´s tips and knuckles in the following order:
0 = little finger´s tip
1 = little finger´s top knuckle
2 = little finger´s middle knuckle
3 = little finger´s base knuckle
4 = ring finger´s tip
5 = ring finger´s top knuckle
6 = ring finger´s middle knuckle
7 = ring finger´s base knuckle
8 = middle finger´s tip
9 = middle finger´s top knuckle
A = middle finger´s middle knuckle
B = middle finger´s base knuckle
C = index finger´s tip
D = index finger´s top knuckle
E = index finger´s middle knuckle
F = index finger´s base knuckle
If the left hand is used for the powers of sixteen,
its possible to count from zero to FF = 255:
00 = little finger´s tip
10 = little finger´s top knuckle
20 = little finger´s middle knuckle
30 = little finger´s base knuckle
40 = ring finger´s tip
50 = ring finger´s top knuckle
60 = ring finger´s middle knuckle
70 = ring finger´s base knuckle
80 = middle finger´s tip
90 = middle finger´s top knuckle
A0 = middle finger´s middle knuckle
B0 = middle finger´s base knuckle
C0 = index finger´s tip
D0 = index finger´s top knuckle
E0 = index finger´s middle knuckle
F0 = index finger´s base knuckle

Cool...
..although, personally, I use finger-binary and count up to 1023 instead. :-)
That's Numberwang!

Interesting idea, but the only time I ever count on my fingers is after a lot of drinking and then even ten fingers can be challenging.

But if you drink a lot, its great for the waitor, when he can count to fifteen with one hand, bringing your drinks with the other...
Concerning finger binary: I dont think its a good idea. Its very acrobatic and less easy to understand. Applied in a kindergarden it would cause rather tears and confusion, than a better understanding of numbers. And the hex 3FF is not that important.

Oh, I agree... I didn't claim that finger-binary was a practical system. :-)
Hardly anyone has the dexterity to do it (independent control of the 4th fingers is a real killer).
But I still enjoy it as a little mental exercise when I'm bored, often using a suitable surface to touch against the tips of the relevant fingers.

Cool, interesting way to remember. Check out this site to convert hex to decimal and vice versa
