ADDITION AND SUBTRACTION OF Hexadecimal Numbers

ADDITION

START adding digits from right to left i.e. from LSB(Least significant digit) to MSB(Most significant digit)

•      If the result is less then 16 write the digit as it is
•      If the result is >=16 subtract 16 from it to get the digit and carry 1 to next digit    for e.g. Let's add C59A  and 68F1
  

SUBTRACTION

START subtracting digits from right to left i.e. from LSB(Least significant digit) to MSB(Most significant digit)

•      If the second digit is greater than first digit burrow 16 from preceding digit
•        for e.g. Let's add C59A  and 68F1
