Complex number - Wikipedia
In mathematics, a complex number is an element of a number system that extends the real numbers with a specific element denoted i, called the imaginary unit and satisfying the equation . Since no real number satisfies the above equation, i was called an imaginary number by René Descartes.

Well, a Complex Number is just two numbers added together (a Real and an Imaginary Number). So, a Complex Number has a real part and an imaginary part. But either part can be 0, so all Real Numbers and Imaginary Numbers are also Complex Numbers. Complicated? Complex does not mean complicated.
Complex Numbers - GeeksforGeeks
Complex numbers are numbers that can be written in the form (a + ib), where a represents the real part and ib represents the imaginary part, a and b are real numbers, and i is an imaginary unit called "iota" that represents √-1 and i2 = -1.

What is a complex number. How to find absolute and argument of it. Learn its standard, polar, and exponential form with the formula.
COMPLEX NUMBERS
In this section we show how to add and subtract complex numbers, and how to multiply a complex number by a scalar (i.e. a real number) using the common operations of addition, subtraction, and multiplication already in use for real numbers, along with their commutative, associative, and distributive (aka foil rule) properties.

Complex Number - from Wolfram MathWorld
Complex numbers are useful abstract quantities that can be used in calculations and result in physically meaningful solutions. However, recognition of this fact is one that took a long time for mathematicians to accept.
Complex numbers | Algebra 2 | Math | Khan Academy
Welcome to the world of imaginary and complex numbers. We'll learn what imaginary and complex numbers are, how to perform arithmetic operations with them, represent them graphically on the complex plane, and apply these concepts to solve quadratic equations in new ways.
Introduction to Complex Numbers
When attempting to solve for x, no real number satisfies the equation. This necessitated the introduction of imaginary numbers, which expanded the number system to include solutions to such problems. Beyond pure mathematics, complex numbers play a crucial role in real-world applications.
