Definition

Complex numbers are numbers that consist of two parts: a real part and an imaginary part. They are written in the form $a + bi$ , where $a$ a is the real number, $b$ b is the imaginary number, and $i$ is the imaginary unit defined as $i = \sqrt{-1}$ i. Complex numbers extend the real number system to include solutions to equations, such as $x^2 + 1 = 0$ , that have no real solutions.

Summary

Complex numbers combine real and imaginary values into a single number system that allows all polynomial equations to have solutions. They can be represented on the complex plane, where the horizontal axis shows the real part and the vertical axis shows the imaginary part. Operations such as addition, subtraction, multiplication, and division can be performed on complex numbers using specific rules. Complex numbers are important in mathematics and are widely used in science, engineering, and physics, especially in areas involving waves, electricity, and signal processing.
