8. Two integers A and B are stored in sign-and-magnitude format. Show how B is subtracted from A. (-23) - (+13) = (-36). Hint: Let A = (-23) and B = (+13) and then use the flowchart for sign-and-magnitude format. Use 8-bits to represent each number in binary. Verify that your final answer in binary is equal to -36 in decimal. Show your work
