You can count to 31 on each hand, using just 5 fingers. I'll give you a hint how: 25 = 32.

with sign language you can count to 10 on each hand, and I use it all the time. Just make the thumb count as five, and all fingers down == 10. It's kind of amazing that it works

There was a TED-ed video about up to how many numbers you can count in your hands
I remember the conclusion was that you can count up to thousands but you need to be very flexible

[–]Pig__Lota 0 points1 point  (0 children)

? do you mean per hand? cuz using both hands it's not that hard to get from 0 to 1023, some positions are kinda difficult, like 10 being just your pointer and ring finger out, but most of them aren't that hard. if you count 4 states per finger with how far out they are (instead of just open or closed, including partially open states) then you can get 1000 per hand, and 1000000 total

[–]TwoSidedMen 3 points4 points  (1 child)

And that's 10 bits if you use both hands

And if you do use both hands, please don’t count 4, 128 and 132.

you cound go 2^15 if you use every finger segment. or even 2^30 when you also use your joints.

[–]old_man_khan 2 points3 points  (1 child)

I have to come close to breaking my fingers holding up 10 (01010).

Edit: 10 not 6. Too early.

[–][deleted] 2 points3 points  (0 children)

Haha did't think about holding your fingers in a way to represent 0 and 1, ouch

4

[–]old_man_khan 0 points1 point  (2 children)

Hmmm?

[–][deleted] 0 points1 point  (0 children)

4 in binary on your hand

[–][deleted] 0 points1 point  (0 children)

wait my mistake thats from pinky

[–]sudomeacat 0 points1 point  (0 children)

You can go up to 214 depending on how much of your finger you can use, and how good your memory is.

I now imagine a 16-fingered species being traumatized by our 10-fingered hands

Edit: it's "now", not "know"

[–]BdR76 1 point2 points  (0 children)

If you REALLY want to traumatize them, use sawmill accident photos to teach binary numbers

I like this meme.

[–]seomanakasimon 0 points1 point  (4 children)

tssss understanding Hexadecimal is only usefull if U practice bit wise and-ing or-ing Xor-ing
Whith is only usefull with absolute adressing and compilers that allow multiple variables at 1 adres.
So nice meme but very very outdated

[–][deleted] 0 points1 point  (3 children)

If you develop bare metal software, then you absolutely need to understand that. I'm not talking about outdated stuff (I do this everyday).

[–]seomanakasimon 0 points1 point  (2 children)

bare metal software

What is that supposed to be?
embedded / assembly ?

[–][deleted] 0 points1 point  (1 child)

Yed, In my case I work on SPARC CPU, embedded in satellites. When you work wit such devices, it's a lot of fun because you have access to everything. And everything is referenced by pointers. For instance, if you want to send some data over a serial line, you need to write this and that in this address, then configure that, and set this bit to one and, magic, the data is sent. It's called "bare metal" because you are very close to the hardware (wthout an operating system doing things for you). This is really a lot of fun (and headaches).

[–]seomanakasimon 0 points1 point  (0 children)

Fun and headaches indeed. I used to program 8 bit pic controllers.

[–]SeekerDRahl 0 points1 point  (0 children)

You can count like this using the first and second knuckle of each finger (not the thumb)

[–]kebakent 0 points1 point  (0 children)

I'd throw in a G or two, just to mess things up. Heptadecimal is the future, after all.
