The mul instruction has 2 operands: one is specified and the other one is implicit. When you write mul cx it means something like: ax = ax * cx. Actually it means dx:ax = ax * cx - the high half of the full 32-bit product is always written to dx. dx will be zero for small products where the result "fits" in ax.
