Using MIPS assembly Calling a Subroutine Make your multiplier code into a function, and call it from a main. You must pass the two numbers to be multiplied into your function using the $a0 and $a1 registers, and return the answer back to main using the $v0 register. Do not load from your .data section or store to your .data section inside the function. You may load from and store to the stack, of course. After the multiplied value has been returned to main, you should place it into a main memory location and then print out the result using syscall. A sentence like "5 times 6 is 30." should be printed out in the terminal.
