It is called an expression.
A number does not contain an operation.A number does not contain an operation.A number does not contain an operation.A number does not contain an operation.
That looks like the description of an EXPRESSION. However, an expression need not have "at least one operation"; a single number, or variable, is a perfectly valid expression.
