The video tutorial explains how to plot two complex numbers, z and w, on the complex plane. It then demonstrates how to calculate the distance between these numbers using the Pythagorean theorem. Finally, it shows how to find the complex number that is exactly halfway between z and w, which involves calculating the midpoint of their real and imaginary parts.

What are the complex numbers z and w introduced in the video?

• z = -2 + 3i, w = 5 + i

• z = 2 + 3i, w = -5 - i

• z = 2 - 3i, w = 5 - i

• z = 3 + 2i, w = -5 + i
