The verb that translates to "to add up" is "sumar." This verb specifically relates to the mathematical action of addition, which aligns perfectly with the phrase in English. In mathematics and everyday contexts, "sumar" is used when referring to combining quantities or calculating totals.

The other verbs refer to different actions: "superar" generally means "to overcome" or "to exceed," "temer" translates to "to fear," and "traer" means "to bring." None of these verbs capture the essence of adding things together as "sumar" does. Therefore, "sumar" is the appropriate choice for the translation of "to add up."
