## Complex numbers calculator

A complex number is an ordered pair of two real numbers (a, b).

To represent a complex number, we use the algebraic notation, z = a + ib with i ^ 2 = -1

The complex number online calculator, allows to perform many operations on complex numbers. The complex number calculator is also called an imaginary number calculator. The complex symbol notes i.

The complex number calculator is able to calculate complex numbers when they are in their algebraic form. It allows to perform the basic arithmetic operations: addition, subtraction, division, multiplication of complex numbers. The calculator makes it possible to determine the module , an argument , the conjugate , the real part and also the imaginary part of a complex number.
