Hello, I am having trouble with some homework. Im an assembly language noob. I need to write a program that does A*B+C*D. I know i Need a multiplication subroutine, but I just dont know how to make one. Here is a link to give you more information http://www.rivier.edu/faculty/bhiggs/web/cs245aweb/assignments/assignment3.htm
As you see, there is no Multiply command, so I would have to create the subroutine and loop it however many times. Any help would be appreciated. Thank you.
