In this article, we will explore the definition and meaning of additive identity in detail.

## Definitions

Additive identity is a mathematical concept that refers to the number that, when added to any other number, leaves the number unchanged. In other words, it is the number that does not change the value of the number it is added to. The additive identity is denoted by the symbol 0.

## Origin

The concept of additive identity has been around since ancient times. The Babylonians and Egyptians used a zero-like symbol to represent the concept of nothingness. The Greeks used the word “μηδέν” (medén) to represent the concept of zero. The modern concept of additive identity was developed by mathematicians in the 19th century.
