**Complex number**is the sum of a real and a imaginary part.**Every complex number**is not real**number**. But**every**real**number**can be said as**complex number**considering imaginary part zero. A is real part & B is imaginary part.Similarly, you may ask, what is the imaginary part of a complex number?

The real

**part of a complex number**z is denoted by Re(z) or ℜ(z); the**imaginary part of a complex number**z is denoted by Im(z) or ℑ(z). For example, A real**number**a can be regarded as a**complex number**a + 0i whose**imaginary part**is 0. A purely**imaginary number**bi is a**complex number**0 + bi whose real**part**is zero.What is a complex number system?

A

**complex number**is a**number**of the form a + bi, where a and b are real**numbers**and i is an indeterminate satisfying i^{2}= −1. For example, 2 + 3i is a**complex number**. The real**number**a is called the real part of the**complex number**a + bi; the real**number**b is called the imaginary part of a + bi.What is the real part of?

A nonzero complex number with zero

**real part**is called an imaginary number or sometimes, for emphasis, a purely imaginary number.
