Using the MARIE computer assembly language, write a program that computes the following expression:

z $($a $*$ b$)*($c $*$ d$)*$ e$.$ The computer will read in the input values a$,$ b$,$ c$,$ d$,$ and e from the keyboard,

and the final result $($z$)$ has to be displayed. In addition, every time an input value is read in$,$ it must be

validated by checking that the input is a positive number. If it is positive display the number on the

screen; otherwise display zero and end the program. Each time a multiplication of two numbers is needed,

it has to be done using a multiplication subroutine. Remember that the MARIE instruction set does not

have an instruction to execute multiplication, you must create a subroutine $($function$)$ that multiplies two

numbers and call it each time you need it$.$ The program must be tested in the MARIE simulator

I made a code but my calculations are wrong. For example if I input the value $2$ for every variablw I get $120$ instead of $32.$ This is my code that I need help with editing.
