https://en.m.wikipedia.org/wiki/Imaginary_unit

WEBThe imaginary unit or unit imaginary number ( i) is a solution to the quadratic equation x2 + 1 = 0. Although there is no real number with this property, i can be used to extend the real numbers to what are called complex numbers, using addition and multiplication. A simple example of the use of i in a complex number is 2 + 3i.

WEBWhat are Imaginary Numbers? Imaginary numbers are numbers that result in a negative number when squared. They are also defined as the square root of negative numbers. An imaginary number is the product of a non-zero real number and the imaginary unit "i" (which is also known as "iota"), where i = √ (-1) (or) i 2 = -1.
