The form like a + bi is a complex number, where i is the imaginary unit and a and b are real numbers. So complex number has real part of a and the imaginary part of b. The online complex operation calculator provides Multiplication Division Square root operation.

Operaction Formula:

Division = (a+bi) / (a+bi)
Multiplication = (a+bi) × (a+bi)
Square root:
   x = b / 2y
   y = sqrt((r-a) / 2)
   r = sqrt(a² + b²)
   r1 = x + yi
   r2 = -x - yi
