In mathematics, a statement of balance or equality between two expressions is referred to as an equation. An equation indicates that the values on both sides are equal, typically expressed with an equal sign (=). For example, the equation 2 + 3 = 5 states that the sum of 2 and 3 is equal to 5, thus providing a clear representation of a relationship where both expressions yield the same result.

A mathematical expression, on the other hand, does not contain an equal sign and merely represents a value, like 3x + 2. An inequality expresses a relationship where one value is less than or greater than another, such as 3 < 5, rather than stating equality. A formula is a specific type of equation that shows the relationship between different variables, often used to calculate values in specific contexts, such as area or volume. Therefore, the term that correctly describes a statement of balance or equality is an equation.
