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 the imaginary unit, satisfying the equation i2 = â1. In this expression, a is the real part and b is the imaginary part of the complex number. If z = a + b i {\displaystyle z=a+bi} , then â z = a , â z = b .
