• You should be able to
  • Given a number and a base other than base 10, convert that number to base 10.
  • Given a number in base 10, convert that number to a new base.
  • Given a number in binary, octal or hex quickly convert any other of these systems.
  • Explain why binary, hex and octal are used in computing
