Use this calculator for z = a + bi arithmetic. Enter the real and imaginary parts of two numbers A and B. The sum is (ar + br) + (ai + bi)i. The product is (ar br − ai bi) + (ar bi + ai br)i. The modulus of A is |A| = √(ar² + ai²).
This page does not divide, conjugate, or convert to polar form. i² = −1 is already built into the product formula.
A real: Real part of the first number.
A imag: Imaginary part of the first number.
B real: Real part of the second number.
B imag: Imaginary part of the second number.
Sum real / Sum imag: Real and imaginary parts of A + B.
Product real / Product imag: Real and imaginary parts of A × B.
|A|: Modulus of the first number.
