    Given: x = a + bi where a and b are real numbers and i = square root of (-1). The conjugate of x is a - bi. The conjugate of the conjugate of x is a - (-bi) = a + bi which equals x which is a+bi. Therefore, the conjugate of the conjugate of a+bi = a + bi. Note: The sum of a number and its complex conjugate is zero.
