Using 8-bit twos complement arithmetic perform the

Question

Given the following decimal numbers:

A = 68 B = 77 C = -29 D = -110

Using 8-bit two's complement arithmetic, perform the following six calculations as they would be done on an 8-bit microprocessor. Recall that subtraction is performed by negating the second operand and adding, i.e. all operations are performed with a binary adder circuit.

1. A+B

2. A-B

3. A+C

4. A-C

5. C+D

6. C-D
