The video tutorial explains how to plot complex numbers on a two-dimensional grid, known as the complex plane. It introduces the concept of complex numbers, detailing their real and imaginary parts. The tutorial then demonstrates how to plot these numbers on the complex plane, where the horizontal axis represents the real part and the vertical axis represents the imaginary part. Several examples are provided to illustrate the process of plotting different complex numbers.
