# Cero vs. Zero — What's the Difference?

By Fiza Rafique — Updated on October 26, 2023
Cero is the Spanish word for the number "0." Zero is the English word for the same number.

## Key Differences

Cero is a term that originates from the Spanish language. It is used to denote the numeral "0" and represents the absence of quantity. Zero, on the other hand, is the English equivalent of this concept. It too represents the numeral "0" and signifies a lack of any numerical value.
Both Cero and Zero serve as crucial linguistic representations of the concept of nothingness in their respective languages. Without words like Cero and Zero, expressing the absence of something numerically would be challenging in Spanish and English.
While Cero is primarily used in Spanish-speaking regions, Zero has its roots in Old Italian but is now widely accepted and utilized in the English language. Both words, though from different linguistic backgrounds, serve the same mathematical and conceptual purpose.
In the realm of mathematics and science, both Cero and Zero are pivotal. Whether you're working on a math problem in Madrid or New York, the understanding of Cero or Zero as the starting point or the absence of quantity remains consistent.
