"Complex" numbers share many properties with the real numbers. In fact, complex numbers include all the real numbers, so you know lots of them already. Such an overachiever.

Suppose that we have two complex numbers \(z_1 = 3 - 2i\) and \(z_2 = 4 - 3i\). In what quadrant is this complex number \(z_1z_2\) located?
