How to Count Until 1023 With Your Fingers

About: I love making stuff, or should I say, invent stuff, because most of the time my inventions end up not being built. I did build a few things though, but they were never solid enough to last. If I build my inv...

On this Instructable I'll show you how to count until 1023 using only your fingers...and some binary knowledge. It's actually quite useless, unless you want to impress mates, but once you can do it, it's fun(well, sort of...) and also since it's my first Instuctable and English isn't my first language please don't be too harsh( ah well if you are I'll post a better one for a more interesting thing). Well then, let us begin.

Step 1: The Principle

Now you should wonder how it is possible to count until 1023 with your fingers since you only have ten of them. The principle is to assign a binary digit(=bit)to each finger, beginning with the one the most on the right and ending with the one the most on the left. The values of the fingers are on the picture (actually, it multiplies by 2 when you go one finger further). Then to count until 1023, you just have to combine these values. If you begin from 1, then raise the first finger, then the second,then both firdt and second, then third, then third and thirst...and that's it(at least for the principle, at first it's hard to keep the count for bigger numbers). Well, I hope this was useful(if not...whatever.It's the only thing I could think of for now).

    This is a great Instructable, but you need to add a main image of the final project to the intro step. Please do that and leave me a message when you have so that we can publish your work. Thanks!

    Hmmm. I've always told my son, "If you want people to think you're intelligent, you have to speak [and type...] as though you are". Yet some writers "refuse" to type in proper English?? Hmmm...
    It's a free [-ish] world so type how you wish, but Instructibles and comments are clearer if written in "proper English". :] (smiley face in case my comment is taken as not "positive and constructive")

    Oh good lord, this was a while ago, jesus christ I regret typung like that ;A;

    I have since graduated myself to typing with legitimate grammar.

    But hey ypure pretty cool for not being harsh over it

    This is a wonderful idea Darkknarf! Although I never saw my youngest stepson do this, as a young child he apparently had a trick with his fingers that allowed him to calculate very quickly - perhaps he was instincively using binary?? When my wife demonstrate this, it looks rather like tickling a standing horse's tummy with the fingers of both hands!
    Love the X-rays - yours?

    Actually no, even though I'd love to have x-rays of my hands to use for Halloween decorations. It's just the only convenient image of hands I found with a Google search. And I thought the x-ray made it more appealing to the eye as a bonus.
