Impedance is the sum of the resistance and the reactance in a circuit: Impedance = Resistance + Reactance. In order to separately track resistance and reactance, impedance is treated as a combination of two numbers rather than just one. You can think of this as a point on a cartesian plane, with one x-coordinate and one y-coordinate.
