Question

what r complex numbers ?

Answer 1

According to Wikipedia, a complex number is a number consisting of a real part and an imaginary part. Complex numbers extend the idea of the one-dimensional number line to the two-dimensional complex plane by using the number line for the real part and adding a vertical axis to plot the imaginary part. In this way the complex numbers contain the ordinary real numbers while extending them in order to solve problems that would be impossible with only real numbers.

Answer 2

Complex numbers come in the form a+bi where a and b are from the real numbers and i is the imaginary number √(-1)
