INTRODUCTION:
Basic binary digits are described as UNSIGNED values. This is because if you
look at the string of bits (zeros and ones) there is no indicator whether or
not this value is positive or negative. You must use an additional symbol "+"
or "-" to indicate the sign of the number. There are some types of number
systems where you can determine the sign of number without using an addition
symbol. You can tell

easy mistake to make. Watch out for this.
**Don't ever forget when converting from an unsigned binary value to signed
representation (1's complement or 2's complement representations) only
negative numbers are changed. If you are still confused then look back at
the odometer type circles from lab comparing unsigned, 1's comp and 2's
complement numbers. You will see that the bit patterns that are used to
represent positive values for all three representations are indentical.
