Real and imaginary parts of a complex number

We can represent a complex number with the expression z = a + bi. "z" is known as the imaginary part of the real number, and "a" is known as the real part of z. Thus, we can write: 2: 3 + 2i. The real part of the number is 3 and the imaginary part is 2. We also have examples of a phenomenon called a pure imaginary number. Now suppose we have an expression like 0 + bi. In this case, the real part of the complex number is 0. When the real part of a complex number is 0, we have an example of the aforementioned pure imaginary number.

We also need to understand what equality means within the context of speaking of complex numbers. when a = c and b = d, we represent the complex number by writing a + bi = c + di. In other words, the variables of the ecomplex number are equal to one another.
