A byte consists of 8 bits. Bits contain 0 or 1.
//byte example: 10010010

How do bytes represent a value?
It depends on the places where bits are turned on (have a value of 1)

For example, you want to represent number 1 (decimal) in binary

128 64 32 16   8 4 2 1  //Sum up this value if the bit is turned on
0   0  0  0    0 0 0 1

0 + 0 + 0 + 0 + 0 + 0 + 0 + 1 = 1

The one above represents number 1 in decimal. 

What is 1 + 1 in binary??

0000 0001
0000 0001 +
--------------
0000 0010

What happend?
We just created 2 in binary! What an amazing world we live in.

128 64 32 16   8 4 2 1
0   0  0  0    0 0 1 0 //we turned on the second bit to create 2

0 + 0 + 0 + 0 + 0 + 0 + 2 + 0 = 2

Starting to make some sense?

Lets add 1 again (2 + 1 in decimal):

0000 0001
0000 0010 +
--------------
0000 0011

Convert to decimal:
128 64 32 16   8 4 2 1
0   0  0  0    0 0 1 1 

2 + 1 = 3

//Happy coding
