I understand the process used to complete this lesson but what is the purpose of this feature? It does not add or subtract binary numbers. I seem to be missing the point of it. What is a practical application of comparing 2 binary numbers in this fashion. Is it used for error checking? Can anyone suggest a purpose? Any help would be appreciated.
