Tutorial - Graphing complex numbers ex 4, 4

The video tutorial explains how to graph real numbers on a complex plane. It begins by clarifying that the expression of a single number is not complex. The tutorial then describes how numbers can be expressed in the form A + BI, where B is zero for real numbers. It demonstrates how to plot the number 4 on the complex plane, emphasizing that it lies on the real axis since it has no imaginary component.
