Question: Let x and y be two positive integers between 1 and 255, where x is greater than y. Show two approaches to calculating x -

Let x and y be two positive integers between 1 and 255, where x is greater than y. Show two approaches to calculating x - y in binary using operations and representations covered in the lecture (one approach, 1 mark only). You should provide values for x and y to use in an example and should explain in a sentence or two why you have chosen these approaches.
