Assembly Language Problem


Question

Alright, our teacher gets mad when we even ask him questions at all about assignments. I've got to write a program that multiplies a 24bit number by an 8bit number to get a 32bit number, in a byte by byte method. If I used max values (ie FFFFFFh and FF) i know i'd have FF as al obviously but after that I'm at a loss. It wouldn't be so hard to me if it weren't for the byte by byte method needed. Like would I move first two FFs of the 24bit to bx and the last 4 F's to cx then multiply out bl by al and bh by al then add them then do the same for cx? I haven't a clue! Any help in the right direction of methodology of thinking would be greatly appreciated. Thanks in advance.
