# Easy way to count in Binary! 1's and 0's

Have you every wanted to count like a computer, or just wondered how computers count this is the instructable for you!

First we need a little information of binary. Computers have 2 numbers in there system except there not numbers there switches. 1 meaning "ON" (like a light bulb) or 0 meaning "OFF"

So...

10110011

would be...

On, off, on, on, off, off, on, on

Then the computer interprets that into its numbering system, which later may convert it into ASCII. Correct 8-bit binary only has 8 digits. There are 16, 32, 64, and 128 bit processors that take more numbers than just 8 at a time. This tutorial is for 8-bit.

## Step 1: Preparing

On the paper write this on the top.

This is the 8-bit binary cheat sheet. Column 8 (the one all the way to the right) is 1, column 7 is just a double of the earlier column, etc.

"Binary Cheat Sheet:

128 - 64 - 32 - 16 - 8 - 4 - 2 - 1"

and pick a number between 1 and 255

My number is 175

Thank you so, so much. I have been trying to figure this out for some time now. No one, and I mean no one was able to get me to understand how to do this. I got on your site for the first time and now I got it. Please keep me informed as I will be using your site for future help.

God Bless you all.

I read this in a book called ''the new how things work+ 80 new pages'' and read a whole chapter on binary numbers an microprocessors and scanners and was really interesting!

8-bit eh? You may have noticed this:
_______________________
128 | 64 | 32 | 16 | 8 | 4 | 2 | 1 |
----------------------------------------
128 = 2 to the 7th power
64   = 2 to the 6th power
32   = 2 to the 5 th power
etc...

Use that ASCII chart up there for reference.

LOL! I can count base 3, 4, 8, 101 Can you show a tutorial for counting in other bases ?

Thanks for the input's I updated my instructable upon your feedback. I hope to find this helpful to some people! (-_- Lemonie!)

Binary isn't much (or any?) use to most people, you might do well to instruct on hexadecimal instead? L

Oh and correct binary only has 8 digits.

As karossii says, you are thinking of a byte. I'm sure your 32 or 64 bit computer CPU deals with numbers over 8 bits.

Your method is sound and quite straightforward but it sounds like you rushed the core part a little bit- you compress all of the instructions on how to actually convert a number into
