For problems 3 and 4, write code that performs the equation below X=(A/B+C)-(D+E * F) You may only use registers A through F, plus X and T. Registers A through F may not be changed, i.e. their values are fixed Register T may be used as a temporary register, and Register X must contain the final answer It is important to remember that operational hierarchy dictates that we first perform all arithmetic inside inner parentheses (if there are any) then inside outer parentheses (if there are any), then do multiplication and division operations before addition and subtraction operations For stack operations, items are placed on the stack in the order that they appear in the expression 4. Show the postfix (Reverse Polish Notation) and then use stack instructions The code should be written in MARIE assembly language
