• Negative values
  • Negative values are also intrinsic and can be represented in a way that is culture independent

    The figure above represents these values:

    negative one       negative two ... and so on

• Statement of our goal
  • This is what we want to achieve:

    Device a way to represent signed integer values         I.e.: we must represent both the positive values and the negative values (including ZERO)
