What is zero in spanish?

In Spanish, zero is "cero." It is an integer that represents the absence of quantity or value, and is typically used as a placeholder in the decimal system. Zero is considered neither positive nor negative, and serves as the starting point for numerical sequences and calculations. In mathematics, zero has unique properties, such as being the additive identity and the only real number that is neither negative nor positive. The concept of zero is believed to have originated in ancient India and was later introduced to Europe through the Arabic numeral system.
