Complete each of the below subtractions. First, convert both numbers to Binary. Use Two's Complement for negative numbers. Then show the addition with result and carry bits. Remember to discard the overflow bit. (a) (4 points) In Binary, show the computation of 91-32. Show both the result and carry bits. (b) (4 points) In Binary, show the computation of 100-47. Show both the result and carry bits
