i tought binary was like, 10010111010101101101101110100010100101010?

it is. in this instance each finger represents a 1 when it is up and a 0 when it's down. so 0000000000 = 0, 0000000001 = 1, 0000000010 = 2, 0000000011 = 3 and 0000000100 = 4. Understand? So that would make your number 1,299,994,592,554.

how to count in binary

this is more detailed

so let's say there are 6 fingers, would the sixth one be 32?it confuses me so much... From what i understand, to some people binary comes to people naturally while others have to learn it.That and a fun fact is that certain puzzles are based on binary,you have to fugure wich ones have to be on (1) and off (0) at the right time and after a while you notice a pattern...

author
knoxarama (author)Deering2008-10-25

yes, because the other five together are 31

author
octavian234 (author)Deering2008-07-16

yes. all you do is take the previous number and multiply it by 2. when you want to write letters you would write in bits or sections of eight

omg a cartoon flipped me off. you 4er!!! really that shouldn't be posted i think. there is no such thing as four anymore

author
uffabrew (author)2008-10-16

The poster/cartoon is nice but seriously flawed. Using all ten fingers and all ten toes would result in 1,048,575 possible combination. Assuming you started counting at zero. I don't know how the cartoonist missed the other 8000 combinations. iMaybe the small toes are worth a little less........1,040,575 is not 2 to the 20th power. 2 to the 20th is 1,048,576, ie One Megabyte. Good job "Spiff" you get the A for the day for pointing out the error!

frederick pohl wrote an essay about this. "how to count on your fingers" it was at the end of the his short-story collection "digits and dastards".

Look ma, 4!

author
zachninme (author)2006-11-14

Base 3 should be possible, Up = 2, bent =1, and down=0...

author
kennytatheguy (author)2006-10-28

number... four.... LOL.. well, anyway, thats great, i never knew binary and it always confused me.

Just don't tell your 4 year old how to tell his age on his fingers.

author
mewantbigboom (author)2006-08-11

is it appropiate counting to 4 like this?

author
savagenarce (author)2006-06-16

Maybe I'm missing something, or maybe I'm just becoming a grouchy old fart, but it seems I can count as high as I want without using my fingers, toes, or any other appendages. 1-2-3-4...a billion and one, a billion and two...

I used to do this when I was a wee child. One of my friends fathers taught us when were around 5 years old. I still use it when I need to add large numbers up. Sometimes people look at you funny, but who cares! I love it. Very glad to see that its being passed on. :):):)

If someone is able to individually control their toes, wow! I can only manipulate the smaller toes on each foot as one unit.

That means four extra bits, and therefore a maximum count of 214 = 16383.

I've counted binary on my fingers for as long as I can remember. Zero to three are the critical maneuvers as your index finger and thumb perform the same motion continuously - the faster you can do that, the faster you can count. The other fingers aren't much of a challenge after that... although it helps immensely with the more difficult numbers if you use your thumb to hold the other downed fingers.

Meh

The fingers and toes panel number should be 1,048,575 (which is 220 - 1). You accidentally turned the 8 into a zero.

That might be dangerous! Make sure your son doesn't go around showing everyone how he can count to 4! Or even worse, 132!

This is amazing... I showed my 6-year old how to do it and he picked it up in just a day! With just a tiny bit of coaching, we've already introduced hexadecimal, and it seemed a natural, simple extension. THANK YOU!!!!
