Write a hexadecimal machine language program that will add and subtract the following numbers: 45(10) + 45(16) - 13(10) - 13(16) + b(16) + (-5)(10). That is 45 in base 10 plus 45 in base 16 minus 13 in base 10 minus 13 in base 16 plus b in base 16 plus negative 5 in base 10. Save each of the instructions in memory and after the instructions save each of the values in memory, including the results. Display the results in hexadecimal and decimal. Run your program and display the memory cells to make sure everything works. Now save the program in a file named ex1-3.mac. Create a log file ex1-3.log that shows the running of your program and displays the memory cells.
