WebbFor any two complex numbers, conjugation is distributive over addition, subtraction, multiplication and division: [ref 1] A complex number is equal to its complex conjugate if its imaginary part is zero, that is, if the … WebbComplex number. A complex number can be visually represented as a pair of numbers (a, b) forming a vector on a diagram called an Argand diagram, representing the complex plane. Re is the real axis, Im is the imaginary axis, and i is the "imaginary unit", that satisfies i2 = −1. In mathematics, a complex number is an element of a number system ...
