16. Using signed-magnitude representation, complete the following operations: +0+(0)=(0)+0=0+0=(0)+(0)= 22. Why do we usually store floating-point numbers in normalized form? What is the advantage of using a bias as opposed to adding a sign bit to the exponent? 32. Compute the Hamming distance of the following code: 0011010010111100 0000011110001111 0010010110101101
