\noindent {\bf Problem statement} Compute $\displaystyle{\int_1^2
\int_x^{x^2} \int_{z}^{zx} xyz \; d?_1 \; d?_2 \; d?_3}$ where $?_1$
and $?_2$ and $?_3$ stand for some ordering of the variables $x$ and
$y$ and $z$ which you must determine. (Only one of the 6 possible
selections ``makes sense'', though!)
