Mark the product of two matrices in a mathematical expression part
A mathematical expression part whose answer is the product of two matrices, $X \times Y$.
By setting the "variable value generator" option for $X$ and $Y$ to produce random matrices, we can ensure that the order of the factors in the student's answer matters: $X \times Y \neq Y \times X$.
