Explain, in one or two sentences, why a particle with charge

q

that successively moves through potential differences of

+50\,\text{V}

-20\,\text{V}

, and

+30\,\text{V}

undergoes the same net change in electric potential energy as if it moved once through a single potential difference of

+60\,\text{V}
