Definition of Expression. An Expression is a mathematical phrase that combines numbers and/or variables using mathematical operations. An expression is a representation of a value; for example, variables and/or numerals that appear alone or in combination with operators are expressions.
In mathematics, an expression is called well-defined or unambiguous if its definition assigns it a unique interpretation or value. Otherwise, the expression is said to be not well-defined or ambiguous.hereas the definition in step 1. is formulated with the freedom of any definition and is certainly effective (without the need to classify it as âwell-definedâ), the assertion in step 2. has to be proved: If and only if, we get a function, and the of definition is well-defined.
