## Understanding Complex Numbers

Complex numbers are mathematical expressions of the form `a + bi`

, where `a`

is the real part, `b`

is the imaginary part, and `i`

is the imaginary unit (`i^2 = -1`

). They are used to represent quantities involving both real and imaginary components.

## The Importance of Complex Number Arithmetic

Arithmetic operations with complex numbers are fundamental in various fields, including physics, engineering, and signal processing. These operations allow for the manipulation and analysis of complex phenomena.

## Introducing the Complex Number Calculator

The Complex Number Calculator is a user-friendly tool designed to automate arithmetic operations with complex numbers. By entering the real and imaginary parts of two complex numbers, the calculator efficiently performs addition, subtraction, multiplication, division, and absolute value calculations.

## How Does the Calculator Work?

The Complex Number Calculator employs mathematical formulas to perform arithmetic operations with complex numbers:

```
Addition: z1 + z2 = (real1 + real2) + (imaginary1 + imaginary2)i
Subtraction: z1 - z2 = (real1 - real2) + (imaginary1 - imaginary2)i
Multiplication: z1 * z2 = (real1 * real2 - imaginary1 * imaginary2) + (real1 * imaginary2 + imaginary1 * real2)i
Division: z1 / z2 = [(real1 * real2 + imaginary1 * imaginary2) / (real2^2 + imaginary2^2)] + [(imaginary1 * real2 - real1 * imaginary2) / (real2^2 + imaginary2^2)]i
Absolute Value: |z| = √(real^2 + imaginary^2)
```
