Example: Representing an Integer
Let's decide that we will use 8 columns or 8 bits to describe an integer in base 2.

  • the seven columns to the right are used to display the number.

  • the left most column tells the sign of the number
    0 for a positive number
    1 for a negative number 
    •
    For instance, with this notation:
    75 (base 10) is 01001011
    -75 (base 10) is 11001011
