Enter the real and imaginary parts of two complex numbers, choose an operation, and the result is shown in a+bi form.
In the form a + bi, where a is the real part, b the imaginary part, and i is √(−1).
(a+bi)(c+di) = (ac−bd) + (ad+bc)i, using the rule that i² = −1.
Multiply the numerator and denominator by the conjugate of the denominator to remove i from the bottom.
