You are tasked to calculate a specific algebraic expansion, i. e. compute the value of f and g for the expression: = ( − + − ) = ( + ) without using any intrinsic multiplication instructions, subroutines, and function calls. More formally, write MIPS assembly code that accepts four positive integers A, B, C, and D as input parameters.

.data

prompt: .asciiz "Enter 4 integers for A, B, C, D respectively:\n"

newLine: .asciiz "\n"

decimal: .asciiz "f_ten = "

binary: .asciiz "f_two = "

decimal2: .asciiz "g_ten = "

binary2: .asciiz "g_two = "
