Learn about our Editorial Process Updated on January 22, 2019 You can talk about math in Spanish by learning a few basic terms. Many of the words are ones you already may know from other contexts. Spanish Terms of Arithmetic Here are the words for the simple mathematical functions and how they're used with numbers: Addition (Suma): Dos más tres son cinco. (Two plus three is five.) Note that in other contexts, más is usually an adverb. Subtraction (Resta): Cinco menos cuatro son uno. (Five minus four is one.) Multiplication (Multiplicación): Tres por cuatro son doce. (Three times four is twelve.) In other contexts, por is a common preposition. Division (División): Doce dividido entre cuatro son tres. (Twelve divided by four is three.) Doce dividido por cuatro son tres. (Twelve divided by four is three.) Entre is another common preposition. Note that all of these sentences use the verb son, which is plural, in contrast with the singular verb "is" of English. It is also possible to use es or the phrase es igual a (is equal to).
