Write an ASM program that evaluates the following expression, using variables: Z = (-A - B) - (-C - D)

1. Declare and initialize the memory variable A to 32-bit signed integer value 543210 and variable B to 16-bit signed integer value -3210.

2. Declare the memory variables C and D and read in their values from the keyboard as 32-bit signed integer value 43210 and 8-bit signed integer values -10, respectively. a. You should display a message asking for the value of the variable, for example: What is the value of C? then b. Read in the value of C from the keyboard and then c. Display the value you have read beside (ie, to the right of) the message What is the value of C?. Then repeat for variable D in the next line.

3. Variable Z should be declared as a 32-bit signed integer.

4. Display the string Z = (-A - B) - (-C - D) alone in a single line.

5. Display the values of all the variables A, B, C, D together in the next line (in the order in which they appear in the expression); each separated by 3 spaces and a semicolumn and 3 spaces again.

6. Display an empty line.

7. Display the final result contained in variable Z, in binary, then in decimal, and then in hexadecimal; each in a separate line.
