WebDividing Complex Numbers. Division of two complex numbers is more complicated than addition, subtraction, and multiplication because we cannot divide by an imaginary number, meaning that any fraction must have a real-number denominator. This idea is similar to rationalizing the denominator of a fraction that contains a radical. WebTo add two complex numbers, z1 = a + bi and z2 = c + di, add the real parts together and add the imaginary parts together: z1 + z2 = (a + c) + (b + d)i How do you subtract …
