3. Repeat above problem assuming the numbers are 2s compliment signed numbers. Use extensions to equalize the length of the operands. (8 points) (Hint: how to use extensions? Since these are mentioned to be 2s compliment signed numbers, each number is a negative number, MSB corresponding to each number is a 1. To equalize the length in this case, should you be padding zeroes in the front of the number or 1's?) Verity your answers by converting the numbers to their decimal equivalents performing the operations (Show all work!) 3. Repeat above problem assuming the numbers are 2s compliment signed numbers.
