Binary logic notes:

Computers only understand 0's and 1's

000 --> 0
001 --> 1

- Since the computer doesn't have a 2, it must use a different combination ( a pattern)

    010 --> 2

how did these patterns come to be?

 # # # #  # # # #
128 64 32 16 4 2 1 

- ex:
    111 = 7

    4(1) + 2(1) + 1(1) = 7

how do we find an odd number in binary?

- only way to find an odd number in binary is to...
    Look at the first place in the binary layout
