Exiting out of the real number system we enter the the imaginary number system. Imaginary numbers are categorized by their use of the imaginary unit i which is represented by the root of -1. When imaginary numbers are combined with real numbers we call them complex numbers. In this post we will explore operations with complex number such as Adding, Subtracting, Multiplying, and Dividing. We will then wrap everything up with simplifying expressions with complex numbers.
