Complex number - Wikipedia
Complex numbers allow solutions to all polynomial equations, even those that have no solutions in real numbers. More precisely, the fundamental theorem of algebra asserts that every non-constant polynomial equation with real or complex coefficients has a solution which is a complex number.

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 Number- Definition, Rules, & Examples - Math Monks
In mathematics, a complex number is the sum of real and imaginary numbers. It is expressed as: It is the standard or rectangular form of representing complex numbers. Real numbers are all positive, negative, rational, and irrational numbers. Some examples are -2, 5.8, 3, and 7 2.

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
Here we can understand the definition, terminology, visualization of complex numbers, properties, and operations of complex numbers. What are Complex Numbers? A complex number is the sum of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z. Here both a and b are real numbers.

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.

A complex number is the sum of a real number and an imaginary number. A complex number is expressed in standard form when written a + b i a + b i where a a is the real part and b b is the imaginary part.
Complex Numbers | Brilliant Math & Science Wiki
A complex number is a number that can be written in the form a + b i a+bi, where a a and b b are real numbers and i i is the imaginary unit defined by i 2 = 1 i2 = −1.
