Algebraic Expression
An expression in algebra is a number, a variable, or any combination of numbers and variables joined by operation symbols such as , , , and . Expressions represent a value but do not make a complete mathematical statement on their own. For example, , , , and are all expressions. A single number like or a single variable like also qualifies as an expression.
