Question 1 Suppose A = 1110 and B = 0100. Calculate A+B and state whether or not overflow has occurred. All values should be expressed in 4-bit 2's complement binary. A+B= Overflow (yeso) Question 2 Suppose A = 0011 and B = 0101. Calculate A-B and state whether or not overflow has occurred. All values should be expressed in 4-bit 2's complement binary. A-B = Overflow (yeso)
