# What are variables in algebra problems?

A 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.
