Typically when we think of counting on two hands, we count up to 10, but fingers can contain much more information than that! This video shows how to think about counting in binary.
+CogitoErgoCogitoSum You could count in decimal with your fingers like you do in binary. You would be able to count up to 100 000 with one hand! But you would need to be able to bend each finger in 10 different ways... I can bend each finger in 4 ways only... Also, counting each finger as 1 is useful for presenting information to other people. They can count how many fingers you are holding up, but it would be hard to tell which one of the 100 000 combinations you are using in a proper decimal system.
+Kingdom of Stornia - Development I can bend them in 10 ways, it's difficult but you can, i'm not sure how to describe it though. ( i am not a contortionist, anyone should be able to do this)
The great thing about finger-counting is, once the process becomes automatic, you don't even need to count. You can just let your fingers go, and at any given point you can stop and know exactly how far you got.
Real reason is that 4 sounds the same as the word "death". And yes, I understand this comment is a joke, but there are some people who dont understand that.
You can count to 242 on one hand and 59048 on two hands if you use the ability to only partially extend a finger and count in ternary. A bit tricky at times, but it works.
I learned this when I was a kid, and practiced it to the point where I could cycle through the numbers with either hand almost without thinking. Initially just as a novelty, but in adult life I have actually come across a lot of situations where it is really useful to be able to store 5-bit numbers physically without pen and paper: Counting elapsed times that run over midnight (or midday if you use a 12 hour clock) by reciting the names of the hours "8 o'clock, 9 o'clock ... 2 o'clock, 3 o'clock" while counting the hours with a hand. Recalling all the elements of a set and counting the elements that meet some criteria (like remembering who you invited to your birthday party and counting if they are vegetarian or if they don't drink alcohol).
A nice property is that if you want to multiply a number by two you simply cycle the fingers position to the left by one, so for exmple 7*2=14 => 111 becomes 1110. More generally if you multiply a number by a power n of two you cycle to the left n times: 3*64=3*2^6=192 => 11 becomes 11000000. (It's obvious, but it's nice to see it so clearly on my fingers!)
yep, it's obvious. when we multiply by 2 in binary, we just shift 1 place higher, because every place value is just double the one below it. And you can see if i multiply for example 100 by 2, you get 1100100 * 10, which is 11001000. ya
Positional counting marks an important step on from tallying or one-for-one counting, since it allows us to represent the many with a few, in this case 31 with 5, or even 1003 with 10. A simpler way in which fingers might have historically come to be used in positional counting and not just tallying involves hand prints (seen on cave walls round the world). On a flat surface put a small pebble between the thumb and forefinger of a hand print, that represents 1. Move it to between the forefinger and middle finger, that's 2. Move it on to between the middle and ring finger, that's 3. And between ring and pinkie is 4. To get 5 leave the pebble where it was and put a second pebble between thumb and forefinger again. Keep on moving and adding like this, and when all four gaps between fingers are occupied, we have 10. We're relying on the fact that 1+2+3+4=10. Instead of hand prints you can use any device with 4 obvious places or spaces, and the simplest I can think of is a cross-hair grid still with us as the + sign. (A 9-space grid is still with us as #.)
jimpozcaner That‘s what I do when counting with them and I must say, it‘s pretty good if you know how to hold your hands up right. Do not ever count with them sideways, it is very uneasy to the eyes. Instead, hold them up vertically as if you were holding two parallel vertical poles, and half raise your fingers instead of fully doing it. Let one hand carry over to the other, with the thumbs being the incremental starting points for both hands. You won‘t be flipping people off, it‘s very easy to read for all involved, and even has this feel of being a two-digit number being read instead of a 10-digit one.
While it doesn't use the same principle, I very much enjoy the Chisanbop finger-counting method, which I learned not too long ago. It gets you to 99, and it's very easy to learn. I use it to count seconds during 20-second screen breaks, without having to look at the screen. The tactile element (tapping) is nice, because it makes it easy to keep track of where you are without looking. It's also easy to increment rhythmically (e.g. every second), since it's like tapping a beat. I often find that I manage to get to 20 in almost exactly 20 seconds.
This is impressive! You are too smart to be able to think of this way of counting to 1000! This way is going to be great with math problems. Congratulations!👏🏻👏🏻👏🏻
I saw a shor of someone teaching this but i skipped it. Later when i was trying to go to bed i had an urge to learn it but i taught my self instead of going on my phone to look it up. It was pretty fun
I think you could use your segments on four of your fingers to count higher. The first segment on your index would be one, the last would represent 3. 4 would be the first segment on your middle finger, 16 on your ring, 64 on your little finger. Tips of all fingers on one hand would be 255 and 6560 on both hands. Hooray for alternative forms of counting on your hands! I also like counting segments for base 12, with ones column on the right segments and dozens colum on the left segments.
You can actually count to any number n^10-1, provided you can hold each finger in n distinct positions. For n=3, a finger down is a "0", a finger up just to the knuckle is "1", and a finger all the way up is a "2". You could count all the way up to either 59048 or RSI that way, whichever comes first.
A bit late to the "show", but that was my reaction. Being a computer geek / programmer / tech / etcetera, it clicked immediately when he started counting through the first time.
I still remember the time our team, a bunch of programmers, used hand gestures not unlike this (we used 4 fingers each hand instead of 5,by disregarding ring finger consistently) to gesture over a few tens of bytes of data. Each gesture encodes exactly one byte of data.
Me neither, even though it looks easy in the vid. 8 is hard enough, but I can just about use my retracted thumb to hold the other fingers down. Soon as I extend it to make a 1 to bring it up to 9 this leaves my hand looking like a claw in an old horror movie. Same goes for other odd numbers except 1,3,7,31, all because of these frequently conflicting tasks on the thumb. I'm still very interested though, and maybe it is possible to construct a shorter natural number sequence (that is count) using only the physically possible finger moves. I'll try.
Yes, I found a small improvement doing it on my left hand. The ring finger (the 8) remains standing slightly proud of the others when I take away my thumb from it to make a 1, whereas on the right hand the ring finger goes back to being pretty much as bent as the others. Interesting also that I can do a 9 even to that small extent with the left only after doing an 8, the fingers just about stay in place after the thumb has been taken away. (I'm right handed by the way). Please tell me your experiences. The whole thing seems as much a question of human physiology as pure arithmetic, and all the more interesting for that.
my brain for no apparent reason: your middle finger is the third finger over. but also my brain for no apparent reason: yes but your middle finger is also your fourth finger but also my computer for no apparent reason: yes but your middle finger is actually your 100th finger...
As a low brass player in a symphony orchestra, I routinely need to count hundreds of bars of rests at a time. I actually taught myself this counting method, with the variation that the pointer finger is one, middle is two, and thumb is 16 (it's a more natural movement that way). There is the added bonus that most musical phrases are in powers of two (think of 8-bar or 16-bar phrases), so the big flips usually line up with a rehearsal mark. No more of this "am I at 30 or 35?" malarky.
I think you'd want to use the thumb for the low bit both times, but I can't think of a good way to show hand ordering. I'm mostly thinking about signaling large numbers across a crowded room or something like that.
I tend to use a less extreme version of this, similar to an abacus, with only 2 changes to normal counting: 1). The place values of your thumbs are multiplied by 5 2). The place values of your right hand are multiplied by 10 I can't count up to 1000, but counting up to 100 is good enough for me
if you came here from Sakurai, he used "palm" as zero, which is the reverse of what this video shows. This video use "fist" as zero. Although the concept is the same but reversed.
And that’s why Sakurai’s fingers were also reversed from what they should have been. 17 is thumb and pinky out, everything else in. Samurai did index, middle, and ring out, the other two in. It’s just the reverse operation
+Ravin Sharma The way I think about this is there is a hard limit that grows from right most finger to the left most finger on a hand. By checking what is the current left most finger that point out, I know the baseline number I'm on. So I'm incrementing from the current baseline number from left to right, but starting the counting sequence from right finger of the hand.
You could count using ternary with finger/thumbs half-up for 1 and count higher, as some have suggest. It's hard enough to do 9 in this binary way, you'd have to be pretty dexterous to do ternary. On the other hand (boom-boom), you could come up with a huge range of positions to represent various numbers. Learn sign language and you'll be able to express any number.
Counting on your digits, what else would you use? I prefer to count on base 12, using the thumb to point at a one of the 12 phalanxes of the fingers. I "only" goes up to 144+12, but it's easier on my hands.
Clever way to flip your audience off without them noticing! Neat though, I might actually end up using this in everyday life, though conceptually in my head. Gives me a tactile thing I can imagine doing as well as a simple image that can store most of the numbers I'd run into on a regular basis.
Wow, that's the first time I see someone else use this method, I thought of it on my own 2 years ago and taught it to a friend. 132 became an inside joke. The only difference is that I twist my left hand so that the thumb is always the smallest number of the hand. 132 still works though.
Actually, you can count still higher if you can leva your finger in half. In this case, we could go all the way until 2*3^10 instead of 2^10. However, it is pretty hard to do what I said and, after counting until 54, my fingers began hurting a little.
you coul also count until 2^11+2^10 if, when completed 2^10, you move an arbitrary finger to some side, as a reminder that you have 2^10. Don't leave it unfolded, just partially. When achieving more 2^10, open it compretely
each of your fingers can be represented as closed or open (0 or 1), therefor 2^5 is the amount of different configurations one hand can be in(32). so both hands(2^10) can actually count up to 1024. ;).
Finger counting in binary... Since some gestures can be awkward, an alternative would be using one hand for 4 bits instead of 5. This would reduce the range to 16 on one hand and 256 on both hands, but it has the benefit that with two gestures (both hands, or two single-handed gestures) you deliver exactly one byte. It also means one gesture matches one hexadecimal digit for the transcriber.
@@vystorm But it aligns to the nibble on one hand and the byte on both hands. Since the byte is common on modern computers, it can be less error-prone when passing computer data through gestures.
@@hikaru-live That is certainly fair, and it is quite a lot easier to do than all five, it's so hard to move the ring finger on it's own. A lot less potential counting though. A compromise would be to use two finger positions on four finger per hand, but it gets a bit messy.
A friend and i came up with this technique too (we are both programmers) Our difference was that our hands were palm-down and the thumb was '1' or '32'
Just for the record, I discovered tgis video on my own, long before I learned about any mention by Nintendo. I have to externalize that knowledge to retain my sanity and grasp on reality.

I can't count up to 1000, but counting up to 100 is good enough for me
if you came here from Sakurai, he used "palm" as zero, which is the reverse of what this video shows.
This video use "fist" as zero. Although the concept is the same but reversed.
And that’s why Sakurai’s fingers were also reversed from what they should have been. 17 is thumb and pinky out, everything else in. Samurai did index, middle, and ring out, the other two in. It’s just the reverse operation
@@Aweso1974 Plus, it was an all ages stream, and he'd be in hot water when he got to four with the fist method.
If you use signed numbers you can count from -512 to 511.
I never thought of counting in binary with my fingers omg.

Oh man. I just learn something weird almost immediately, Thanks! A need trick to teach my nephew and niece. What is this system of counting called?
+Ravin Sharma The way I think about this is there is a hard limit that grows from right most finger to the left most finger on a hand. By checking what is the current left most finger that point out, I know the baseline number I'm on. So I'm incrementing from the current baseline number from left to right, but starting the counting sequence from right finger of the hand.
+Ravin Sharma I believe it's called finger binary.
Ravin Sharma
Well basically it's binary numbers
Up fingers are 1s, fingers not stood up are 0s
Awesome educational video as usual thank you. Now adding our toe fingers to this, would go as high as 2**20 :)
You could count using ternary with finger/thumbs half-up for 1 and count higher, as some have suggest. It's hard enough to do 9 in this binary way, you'd have to be pretty dexterous to do ternary. On the other hand (boom-boom), you could come up with a huge range of positions to represent various numbers. Learn sign language and you'll be able to express any number.
Counting on your digits, what else would you use?
I prefer to count on base 12, using the thumb to point at a one of the 12 phalanxes of the fingers. I "only" goes up to 144+12, but it's easier on my hands.
If you set 0 = finger down, 1 = finger half way, 2 = finger up (base 3) you can count all the way to 3^10 -1 :)

and if you can move your hairs in your head in 100 ways then you can almost count to 1.0e400 xD
aka googol^4 lol xDDD
I cant do 8 or 9 since my ring finger can't move individually from my middle finger.
+jojojorisjhjosef Try moving the fingers to be kept down in front of eachother, or close together, so they're held down and don't come up by reflex.
jojojorisjhjosef I have the same problem. This may be some anatomical precondition. In fact, a can raise the ring finger, but only halfway.
Perfect for fuzzy math!

8 is your index finger.
@@drone_better7757 no, 8 is the ring finger
If you include a finger position of half-bent, you can count up to nearly 30,000
This is so cool and I'll definitely be passing it on to as many people as I can!
I love that the finger movement were on beat with the music.

Clever way to flip your audience off without them noticing!
Neat though, I might actually end up using this in everyday life, though conceptually in my head. Gives me a tactile thing I can imagine doing as well as a simple image that can store most of the numbers I'd run into on a regular basis.
Wow, that's the first time I see someone else use this method, I thought of it on my own 2 years ago and taught it to a friend. 132 became an inside joke. The only difference is that I twist my left hand so that the thumb is always the smallest number of the hand. 132 still works though.
Thanks Sakurai-san very cool!
I'm here because of smash bros
Actually, you can count still higher if you can leva your finger in half. In this case, we could go all the way until 2*3^10 instead of 2^10. However, it is pretty hard to do what I said and, after counting until 54, my fingers began hurting a little.
you coul also count until 2^11+2^10 if, when completed 2^10, you move an arbitrary finger to some side, as a reminder that you have 2^10. Don't leave it unfolded, just partially. When achieving more 2^10, open it compretely
each of your fingers can be represented as closed or open (0 or 1), therefor 2^5 is the amount of different configurations one hand can be in(32).
so both hands(2^10) can actually count up to 1024. ;).

Thank you Sakurai, very cool
teacher: the test is easy.
the test:
Finger counting in binary... Since some gestures can be awkward, an alternative would be using one hand for 4 bits instead of 5. This would reduce the range to 16 on one hand and 256 on both hands, but it has the benefit that with two gestures (both hands, or two single-handed gestures) you deliver exactly one byte. It also means one gesture matches one hexadecimal digit for the transcriber.
That's roughly ¼ the digits though
@@vystorm But it aligns to the nibble on one hand and the byte on both hands. Since the byte is common on modern computers, it can be less error-prone when passing computer data through gestures.
@@hikaru-live That is certainly fair, and it is quite a lot easier to do than all five, it's so hard to move the ring finger on it's own. A lot less potential counting though.
A compromise would be to use two finger positions on four finger per hand, but it gets a bit messy.

A friend and i came up with this technique too (we are both programmers)
Our difference was that our hands were palm-down and the thumb was '1' or '32'
Just for the record, I discovered tgis video on my own, long before I learned about any mention by Nintendo.
I have to externalize that knowledge to retain my sanity and grasp on reality.
