For the following pair of decimal numbers X = 42 and Y = 25 perform the calculations -X-Y in signed 2's complement arithmetic. Use 7 bits (including the sign bit) to represent the numbers. Follow the steps below: a) (5 points) Express X, -X, Y and-Y in signed 2's complement form. (Hint: First convert X and Y to binary, then Obtain-X and Y by using 2's complements) b) (5 points) Perform-X-Y. Show the result in signed 2's complement form. Was there an overflow? Why?
