You can count to 14 with just the segments of one hand which makes my head hurt less than bit flags

and China has well established hand gesture for 0-9 on one hand.

and even if you don't know that, it's quite easy to count to 12 using finger segments.

I chuckled at 4 (my favorite number!) when I just tried out counting to 31

China? The 0 to 9 single handed gestures are used for a lot outside of that. Like divers use that, all kinds of trades, and the military.

FYI anyone counting in binary on their hand(s) is decidedly not a normal human.

Now I had to try it out and I'm very proud of how each finger played along

Use a 0-255 range to represent the amount of rotation for each finger knuckle and you get up to like 2⁹⁶.

Akshully, they would be counting to 11,111. That's nearly 100,000!

Rather than assigning each finger the same value of 1, assign them values of 1, 2, 4, 8, and 16. Then there's some combination of fingers that can represent any value from 0 to 1+2+4+8+16=31. It's like using digits to count instead of tally marks.

I work with binary every day or a notation of it, don’t worry

It’s 2026. You can write the top voted nerd joke and still be dead wrong about the math. We’re in the “You’re absolutely right” era now.

Which comment is wrong about the math? If you include 0, then 0 to 31 is 32 different combinations.

The OP. It’s 32 not 31.

E: fine I misread. Im leaving it up so the downvotes can teach me some humility

A five-bit value can contain any number from 0-31. So if you treat your fingers as bits...

Sumerians, 4-5000ya counted to 12 on one hand. 4 fingers with 3 sections each with the thumb as a pointer. Then the other hand counted off 5x12 which gave us yhe hexadecimal system of counting which is still in use today.

I can count to 31 in one hand in binary. It's not a super useful skill, but it's won me a bar bet more than once.

If you add things like arm position and rotation, you can add even more bits. Using 4 arm positions and 2 rotations, you can get a full byte of data with one hand.

I want to go to the kinds of bars where counting in binary wins bets. Most of the time it's things like "open a beer bottle with your eye socket".

9

The trick is to be the one making the bets and to word them in a way that makes the losing side sound like the winning side (or one that generates enough curiosity about how you can actually do it that people accept the bet knowing you probably have a trick).

Sexagesimal, hexadecimal is base 16. You could say that simply improving on mathematics lead to the hexadecimal system eventually but they did not create the hexadecimal system.

Use your thumb to "point" (touch) a section of your index finger, middle finger, ring finger, pinky...now move up a section of the finger.

Tada you learned it.

The other hand goes 1 when you maxed out your finger sections, then 2 when you do it again where one equals 12 and 2 equals 24 etc.

There's really nothing to it, no research needed...just attempt to mimic what the comment describes and you're there.

Imagine what masturbation with that bad boy must be like!!! Hoooooooooo baby!

The joke is he had 8 fingers, which is a mutation from living near Chornobyl.

lol, I guess I was wrong then - I was about to say that OP seems to think the joke is a lot more difficult (with the post title and 'wait what' reaction) than it actually is.

Fun fact you can count to 27 if you cut your hand and count the bones.

Protip: you can count to one by counting your dick, but some people will count zero instead.

I can count entirely on one hand with ASL. 1-10 are static hand positions

I can count to twelve on one hand like the Babylonians

You can count to 242 using ternary numbers if you give each digit three states instead of two.
