A complex number is a number that can be expressed in the
form of a + bi.
Where a and b are real numbers and i is an imaginary unit.
In this expression, a is the real part and b is the imaginary part
of the complex number.

Where a and b are real numbers and i is an imaginary unit.
In this expression, a is the real part and b is the imaginary part
of the complex number.

When we combine the real and imaginary number, then a
complex number is formed.
Real Number + Imaginary Number = Complex Number

Real Number + Imaginary Number = Complex Number
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.
