Imaginary numbers are numbers that when squared have a negative result, such as the square root of -1. While imaginary numbers seem impossible, they allow solutions to equations like quadratic equations and have important uses in engineering and physics. Imaginary numbers are represented by an "i" and have opened up new areas of mathematics and applications.
