*An Imaginary number is a number that when squaring it gives a negative result.

*An Imaginary number is a number that when squaring it gives a negative result.

*For e.g. {-4}^2 =16. Because a negative times a negative is positive.

*For e.g. <math>{-4}^2</math> =16. Because a negative times a negative is positive.

*A complex number is a number is in the form  <math>z = a + bi</math>, where <math>a</math> and <math>b</math> are real numbers and <math>i</math> is the imaginary unit. Where <math>i=\sqrt{-1}</math>.
