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.

In this section we give a very quick primer on complex numbers including standard form, adding, subtracting, multiplying and dividing them.
Complex Number - Definition, Formula, Properties, Examples
Complex numbers have applications in many scientific research, signal processing, electromagnetism, fluid dynamics, quantum mechanics, and vibration analysis. Here we can understand the definition, terminology, visualization of complex numbers, properties, and operations of complex numbers.
5.7: Complex Numbers and Their Operations - Mathematics LibreTexts
The result of adding, subtracting, multiplying, and dividing complex numbers is a complex number. The product of complex conjugates, \(a + bi\) and \(a − bi\), is a real number.
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.
