Counting and equating in binary

Give a general description of the Instructablethis is my second binary instructable. This goes into math equations done in binary. section 1 shows how to count binary with your hands, while section 2 shows you in written form.

Just a side note, when counting in binary, you should always use at least 8 digits. In this instructable, i will not.

Step 1 The finger digits (part 1)

Each finger represents a number. These numbers, when used together, are added to create a new number.
Notice that each number doubles as it goes on. To continue, place your hands together and continue at 32.
The number with all five fingers is 31. On the next hand, you can go up to 1942. This includes every number from 0-1942.

 binary code should atleast be wrote out in 8-bit coding 
you only have 6 up there

i was just pointing out the basics, but i'll add that in there. Thanks

This day and age no one gives the Arabs the credit their due. Historically they were also known as the most tolerant people too!

Wow this is really interesting, I've understood all the adding and subtracting but with the row of binary there I'm stumped, what do i do with it? awesome explaining by the way, 5 stars!

1-10 1. 0001 2. 0010 3. 0011 4. 0100 5. 0101 6. 0110 7. 0111 8. 1000 9. 1001 10. er..... i don't know.

10. 1011

[reds322]

No, 10 is 1010 1011 is 11. Anytime you see a binary number that ends in 1 it will be odd.

I can count 1-3 and 5-# but, I cant count to four in a classroom.

[Millawi Legend]

is 4 100?

[knoxarama]

yes

[PKTraceur]

No, 4 is the middle finger. Here, put it up!

[knoxarama]

4 isn't a pretty number. 252 is worse.

[Arbitror]

Don't you mean 132?

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".

[Germy]

Two hands can count to 1023, not 1942.
All five fingers up on one hand = 31... (1+2+4+8+16...)
All five fingers on both hands = 1023... (...+32+64+128+256+512)

[knoxarama]

i may have typed in the calculater wrong. i didn't have long to get this on.

[2fst4u]

you didnt explain anything. "yo add you just change your fingers to match the number" sure, this defines adding but doesnt tell me how to do it

[knoxarama]

your fingers just represent it. You don't solve problems with a pen or paper, it just acts as memory and communication.

Your last equation show 13-9 equals 8. :P

[knoxarama]

the imaging was having some problems.
