                 1.5.2 Hexadecimal Subtraction
                 Hexadecimal subtraction can be done by following three different methods.
                 •  Borrow method
                 •  15’s complement method
                 •  16’s complement method

                 Hexadecimal Subtraction by Borrow Method
                 Hexadecimal subtraction can be performed by borrow method with the same way as decimal subtraction.
                 The steps to be followed are:

                 1.  Subtract each digit of minuend and subtrahend starting from rightmost column (LSB).
                 2.  If the minuend digit is smaller, borrow 16 from the previous digit.

                 Example 1:  (FCA)  - (94F)
                                16      16
