a) Perform the following additions and subtractions of the following unsigned integers. Use the fewest number of bits n to represent both operators. Indicate every carry (or borrow) from Co to cn (or bo to bn). For the addition, determine whether there is an overflow. For the subtraction, determine whether we need to keep borrowing from a higher bit.
