What Is The Difference Between Expression And An Equation

An expression is a combination of numbers, symbols, and operators that when evaluated, produces a single value. It does not contain an equals sign and cannot be solved to find a value. Expressions are typically used to calculate values that are used in equations.

An equation is a mathematical statement that says two expressions are equal. The expressions on either side of the equals sign can be solved to find an unknown value. An equation usually contains an equals sign and at least one unknown variable.
