**variable**is a symbol that represents an unknown number. It will be equal to a number, but you don't know what that number is yet. Until you figure it out, you use the symbol. The

**variable**you most often see is x. In an

**algebraic**equation, a

**variable's**real meaning is determined by the things around it.

Beside this, what is a variable in algebra?

**Algebra** - Basic Definitions A **Variable** is a symbol for a number we don't know yet. It is usually a letter like x or y. A number on its own is called a Constant. A Coefficient is a number used to multiply a **variable** (4x means 4 times x, so 4 is a coefficient)

Subsequently, question is, what are the 3 types of variables? The things that are changing in an experiment are called **variables**. A **variable** is any factor, trait, or condition that can exist in differing amounts or **types**. An experiment usually has **three** kinds of **variables**: independent, dependent, and controlled.

Also asked, what are the variables in the expression?

A **variable** is a symbol that stands in for an unknown value in a mathematical **expression**. We can use any symbol as a **variable**, but letters are most commonly used. A term is a single number, **variable**, or a number and a **variable** multiplied together.

How do you define a variable?

A **defining variable** is a symbol, such as x, used to describe any number. When a **variable** is used in an function, we know that it is not just one constant number, but that it can represent many numbers. **Variables** are instrumental in understanding problems relating to graphing.
