Using the model CPU demonstrated in class, write code using the simple machine language of Appendix C to solve the following problem: $40+23-8.$ Store the result in memory location EE$.$ Remember that the model CPU uses hexadecimal values, so you will need to represent the decimal values in the problem in hex. You will then need to convert the number $8$ from a positive to a negative number, in your code, and then add the three numbers together.
