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

- a is called the real part of (a, b);
- b is called the imaginary part of (a, b).

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.

The **complex number calculator** allows to **calculates** the **sum** of
**complex numbers** **online**, to calculate the sum of complex numbers `1+i` and
`4+2*i`, enter complex_number(1+i+4+2*i) , after calculation, the result `5+3*i` is returned.

The **complex number** **calculator** **calculates**
the **difference** between **complex numbers** online, to calculate the difference between
complex numbers `1+i` et `4+2*i`, enter
complex_number(1+i-(4+2*i)) , after computation, the result `-3-i` is returned.

The **complex number calculator** allows to **multiply complex numbers**
**online**, the multiplication of complex numbers online applies to the algebraic form of complex numbers,
to calculate the product of complex numbers `1+i` et `4+2*i`, enter
complex_number((1+i)*(4+2*i)) , after calculation,
the result `2+6*i` is returned.

The **complex number calculator** can **divide complex numbers online**
, to divide complex numbers `1+i` et `4+2*i`, enter
complex_number((1+i)/(4+2*i)) , after calculation, the result `3/10+i/10` is returned.
