##### Example of Complex Number

##### A complex number is a number that can be expressed in the form **a + bi**, where a and b are real numbers and i is an imaginary number.

A complex number is a sub category used to differentiate numbers in mathematics. Complex numbers incorporate real numbers and an imaginary number.

Real numbers are practically any and all numbers. Real numbers include Whole Numbers, Rational Numbers and Irrational Numbers. Real numbers can be positive, negative, and zero. In fact, any number you can think of is a real number. However, real numbers do not include infinity and imaginary numbers.

Imaginary numbers are numbers that are not real numbers. An imaginary number is defined as the square root of -1. *i* = √(-1)

A complex number is a combination of two numbers, a real number and an imaginary number. It is defined as *a + bi*, where *a* and *b* are real numbers and *i* is an imaginary number.

Examples of Complex Numbers:

- 5 +
*i* - 46 + 3
*i* - 0.6 - 4.4
*i* - -9 + π
*i* - √3 +
*i*/3
