Variables in algebra are letters such as x y v g or call it any letter you want that can be used to represent unknown numbers. In the case of x 2 6 we can solve it to find that x 4. In algebra variables are placeholder letters capitalized and lowercase that represent the unknown or what you re solving for. This video shows you what variables can look like and what they mean.

Variables are seen in almost all math applications beginning with algebra. In x 2 6 x is the variable. A coefficient is a number used to multiply a variable 4x means 4 times x so 4 is a coefficient variables on their own without a number next to them actually have a coefficient of 1 x is really 1x. It will be equal to a number.

But in something like y x 2 a linear equation x can have many values. Splashlearn is an award winning math learning program used by more than 30 million kids for fun math practice. In mathematics a variable is a symbol which functions as a placeholder for varying expression or quantities and is often used to represent an arbitrary element of a set in addition to numbers variables are commonly used to represent vectors matrices and functions. Why variable when it may have just one value.

In general it is much easier to always call it a variable even though in some cases it is a single value. In this lesson learn why variables are not something to be afraid of or some concept that is impossible to grasp. Making algebraic computations with variables as if they were explicit numbers allows one to solve a range of problems in a. It is usually a letter like x or y.

Basically whenever we do not know the value of a number we use a variable until we figure out what the number is. Definition of variable explained with real life illustrated examples.
