Web16 sep. 2024 · z is real if and only if ¯ z = z. Division of complex numbers is defined as follows. Let z = a + bi and w = c + di be complex numbers such that c, d are not both zero. Then the quotient z divided by w is z w = a + bi c + di = a + bi c + di × c − di c − di = (ac + bd) + (bc − ad)i c2 + d2 = ac + bd c2 + d2 + bc − ad c2 + d2i.
