Complex numbers in the form

$r (cos θ + i sin θ)$ $r(costheta+isintheta)$

cannot be directly added together.

The correct way to add two complex numbers is to convert them to rectangular form and do componentwise addition.

How do you add (-1-3i)+(-1+5i)(−1−3i)+(−1+5i)(-1-3i)+(-1+5i) in trigonometric form?
