= Well-defined expression
{wiki=Well-defined_expression}
A well-defined expression is a mathematical or logical expression that is clear and unambiguous in its meaning. This typically means that the expression follows the accepted rules of mathematics or logic and yields a unique, consistent result regardless of how it is interpreted within its given context. For example, the expression \\(2 + 3\\) is well-defined because it has a clear and universally accepted result: \\(5\\).
