1. For each problem, perform the addition or subtraction operation, giving the sum or difference in hex using the same number of hex digits as the original two operands. For each operation, state whether or not overflow occurs. For each sum, state whether or not there is a carry; for each difference state whether or not there is a borrow. For each problem, interpret the operations as 2s complement signed and convert the problem to the equivalent decimal problem; verify that the signed interpretation is correct when there is no overflow.

For each problem, interpret the operands as unsigned and convert the problem to the equivalent decimal problem; verify that the unsigned interpretation is correct when there is no carry (borrow for subtraction).
