Algebraic Expression

An expression in algebra is a number, a variable, or any combination of numbers and variables joined by operation symbols such as $+$ , $-$ , $\cdot$ , and $\div$ . Expressions represent a value but do not make a complete mathematical statement on their own. For example, $3 + 5$ , $n - 1$ , $6 \cdot 7$ , and $\frac{x}{y}$ are all expressions. A single number like $7$ or a single variable like $x$ also qualifies as an expression.
