I am not asking you to do the whole thing. I was just hoping you could give me a little direction, as I have no clue how to begin. I am to use the raspberry pi emulator and doing my work in leafpad. Any help or a little direction will be greatly appreated.

The purpose of this program is to get the student to use the stack to pass parameters to and from their own defined subroutines/functions in ARM Assembly Implement a simple four function integer calculator (addition, subtraction, multiplication and division) that meet the following requirements: 1. Each function must be accessed as a subroutine/function (ARM instruction BL). 2. The operands are passed to the function via the stack. Use the ARM pseudo instructions PUSH and POP. To ensure you are properly implementing the stack the registers used in your main routine to hold the operands must be different than those used in the subroutines. For example, your calling routine will push r4 and r5 on the stack but the called routine will pop into registers r10 and ril 3. The function returns the results on the top of the stack 4. Your program is to print a welcome/instruction messages to the user. 5. The user is prompted to enter positive integers and the operation to be performed. 6. The program shall verify the user input is valid and report any entry errors. Ensure your program checks for division by zero. 7. The program shall perform the calculation and report any overflow errors. 8. Since the ARM Assembly does not have a division instruction the program will implement a subtraction algorithm to perform division. The quotient and remainder will be return by the division function. 9. Display the results of the operation. Ask the user if they want to continue with another calculation or quit the program
