Write a machine-language program to add the three numbers 8, -5 and -2 and output the sum on the output device. Note-the inputs can be hard coded in data storage at the end of your code. The accumulator holds 16 bits so use 16-bit Twos Complement for the -7 and do not use the subtract instruction. Write it in a format suitable for the loader and execute it on the PEP/8 simulator. You may only use instructions in Fig 4.6. (Use the Fig 4.6 revised found with the HW2 assignment) You shall submit:

A. written algorithm

B.Your commented program similar to the Machine Language (hex) of Fig 4.35

C. The hexadecimal program suitable for the Pep/8 loader. (Cut & paste the text into your document so I can check your code)

D. A screenshot of your program output screen

E. Explain the range of numbers that this will work correctly
