                      OPERATIONS ON BINARY NUMBERS


                 Let's learn the basic operations on binary numbers.

                 Binary Addition

                 Binary addition is similar to the addition of decimal numbers. In the binary number system, when
                 the value of addition exceeds the value 1, say 10 or 11, then 1 is carried over to the left of the current
                 position. The rules for adding two binary digits are given below:

                                                  X             Y               X + Y
                                                  0             0             0 + 0 = 0
                                                  0             1             0 + 1 = 1

                                                  1             0             1 + 0 = 1
                                                  1             1        1 + 1 = 10 (carry 1)

                 For example, let us add the binary numbers (101111)  and (10111) .
                                                                       2
                                                                                    2
                                                      1    1  1  1  1    _____  Carry bits
                                                      1    0  1  1  1  1

                                                  +        1  0  1  1  1

                                                  1  0     0  0  1  1  0
