## Definition

When it occurs in a mathematical equation, a **variable** is often referred to as an **unknown**.

In the specific context of elementary algebra, the ugly misnomer **pronumeral** is frequently found in Australia. This was introduced by extension of the concept of a pronoun: a symbol that **stands in** for a **numeral**, by which the term number is actually meant.

Thankfully the term appears not to have caught on in general.
