[OS X TeX] Macro for multiplying numbers

[Kapila Rohan Attele]

I made  a macro for multiplying integers

\def\mul#1#2{\newcounter{a}\newcounter{b}\setcounter{a}{#1}\setcounter{b 
}{#2} \multiply \value{a} by \value{b} \the\value{a}}

It can multiply two integers (correctly), but  given 3 to multiply  
\mul{\mul{4}{5}}{6} it complains missing number, treated as zero.
How to define a macro that associativity to multiply more than two?
