    For example, let us add the binary numbers (101111)  and (10111) .

                  Binary Subtraction

                  In binary subtraction, a binary number of lower value is subtracted from the binary number of higher
                  value. The given table explains the subtraction of digit Y from digit X. If Y is greater than X, then 1 is
                  borrowed from the next position. When the binary digit 0 borrows 1 from the next most significant
                  digit, it becomes 10.

                                    X                   Y                               X – Y
                                    0                   0                             0 – 0 = 0
                                    0                   1               0 – 1 = 1 (borrow 1, so that 10 – 1 = 1)
                                    1                   0                             1 – 0 = 1
                                    1                   1                             1 – 1 = 0

                  For example, let us subtract the binary number (111)  from (1000) .
                                                                        2

                                                     –       1     1    1

                     Modern day binary number system was invented by Gottfried Leibiniz in 1679.

                  REAL-LIFE EXAMPLES IN COMPUTING

                  Here are some real-life examples of computing using the binary number system:

                      Computer storage: All data stored on a computer, such as documents, images, and videos, is stored
                     in binary. For example, each letter or character you type is converted into binary code that the
                     computer can process.

                       Digital watches: A digital clock shows time in hours, minutes, and seconds, and all of these are
                     represented using numbers. The clock uses binary to store and display the time. The watch uses
                     logic gates (little electronic switches) that are either "On" or "Off" to keep track of the count.
