Statements are made up of expressions.

Expressions can be made up of a combination of literals, variables, and operators.

An operator is a symbol used to control how the terms of an expression are to be evaluated or manipulated. There are arithmetic operators, relational operators, logical operators, bitwise operators, and assignment operators.
