Question: How to enter complex numbers into Maple TA

I am trying to create a question that generates two complex numbers and asks for the product of the two complex numbers.

This is what I have so far in the algorithm box of the question creator but it doesn't give me the correct answer:

$a=5 + 20*I;
$b=4 - 12*I;
$ans= maple("evalc($a*$b)");

This is my first time using MapleTA. Any help would be appreciated.
