## ze·ro

(zîr′ō) The numerical symbol 0, representing a number that when added to another number leaves the original number unchanged.

*Did You Know?**Zero*is not nothing! It is a number that stands for nothing, and this is an important distinction. In many ways, zero is the most important of all numbers. When zero is added to or subtracted from a number, it leaves the number at its original value. Zero thus makes negative numbers possible. A negative number added to its positive counterpart always equals zero. Zero is also essential to representing many numbers, such as 203 and 1024. In these numbers zero serves as a placeholder in the system known as

*positional notation*. Thus in 203, there are two hundreds, zero tens, and three ones. In other words, zero indicates that the value of the tens place is zero. In 1024, zero indicates that the value of the hundreds place is zero. When you think about it, if we didn't have zero, we wouldn't have hundreds, thousands, or millions in our number system.

**ZERO**

Existen varias palabras que pueden usarse en lugar de zero según el contexto. Zero es el término más general en inglés americano, que se usa en la mayoría de los casos. En inglés británico se usa normalmente en matemáticas y ciencias para referirse a temperaturas u otras escalas de valores, como por ejemplo en las frases zero population growth (crecimiento de población cero), o zero inflation (índice de inflación cero).

Nought se usa en inglés británico para leer números decimales, como por ejemplo nought point nought seven: 0.07 (en inglés se usa el punto en vez de la coma como separador decimal) y en las calificaciones: nought out of ten (cero sobre diez).

O (pronunciado igual que la letra o) se usa en inglés británico en los números de teléfono: O one four one : 0141. También se usa en secuencias de dígitos que no representan cantidades numéricas, como por ejemplo en tarjetas de crédito o números de cuentas bancarias.

Nil se usa normalmente en el Reino Unido en los tanteos deportivos: Liverpool won five nil (Liverpool ganó cinco a cero).

Nothing es el equivalente americano de nil, aunque también se usa a veces en inglés británico.
