Imaginary Numbers

Imaginary numbers are multiples of the square root of -1. Since the square of every single number -positive or negative- is always positive, it is impossible to find some Real number whose square is -1. Thus, the imaginary unit “i” was invented, with the sole property that “i” squared is equal to -1. Imaginary numbers are expressed as multiples of “i”: for example, the square root of -4 is 2i.
