what mathematicians agreed on an so that numercial expressions would have only one value?
No, it can contain variables.
A Numerical Expression is an expression only using numbers.
A expression that only contains numbers is a Numerical
They do not apply to all expressions - only to those expressions whose elements are either real numerical constants or variables which can only take real values.The set of real numbers is closed under the operations of arithmetic. As a result each term in an expression, which will be made up of real constants or real variables, will also be a real constant or variable. And since each term in the expression is real, the closure implies that their combination is also real.
