How do binary numbers work?

Question

i just CANT UNDERSTAND I dont know why !

Answer 1

So, in our "decimal" system, we have ten numbers (0 through 9). However, in Binary, you only have two (0 and 1). So, to represent numbers, we use the powers if two (since there are two numbers in Binary). So, we have 1, then 2, then 4, 8, 16, 32, et cetera. Imagine each number as it's own box. So, with the number nine, we fill up the box for 1 and the box for 8 (1 + 8 = 9). So the binary for 9 looks like this: 1001 (box 1 is filled, box 2 is empty, box 4 is empty, box 8 is filled).

Answer 2

It's a formula my friend just Google binary. all it means is everything is represented through a switch. you know on/off == I/0. works just like that through a processor.
