The imaginary unit is defined as the square root of negative one.
Thus, imaginary numbers include ''i'' itself as well as 4''i'', -3''i'' and ''i''/6.
Imaginary numbers are just as real as any other numbers (the name "imaginary" does not imply anything substandard about their status of existence). They are called imaginary numbers simply to contrast them with the set of real numbers, which had been discovered much earlier and therefore were already named.
Real numbers and imaginary numbers taken together form the complex numbers. An example of a complex number is 17 + 3''i''.

imaginary number
An '''imaginary number''' is any multiple of the imaginary "unit" ''i''.The imaginary unit is defined as the square root of negative one.
Thus, imaginary numbers include ''i'' itself as well as 4''i'', -3''i'' and ''i''/6.
