# Operator and Expression

### Expressions and Operators

Operators enable us to perform an evaluation or computation on a data object or objects. Operators applied to variables and literals form expressions. |

An expression can be thought of as a programmatic equation. Therefore, an expression is a sequence of one or more data objects (operands) and zero or more operators that produce a result. |

An example of an expression follows: |

x = y / 3; In this expression, x and y are variables, 3 is a literal, and = and / are operators. This expression states that the y variable is divided by 3 using the division operator (/), and the result is stored in x using the assignment operator (=). Here the expression is described from right to left. |
