I need help with ARM assembly program :

Using the following code as basic :

1 ) Write a program code that is able to calculate the following : Result = A + ( B * C ) - D

Place the result as the return value so you can print it afterwards in the command prompt.

2) This time, use MLA instruction to reduce the number of instructions in question 1.

Place the result as the return value so you can print it afterwards in the command prompt.

- I need to save two questions in separate .s file. ( Please use the given source to complete ).

Thank you very much.
