An expression is a collection of two or more terms that perform a mathematical or logical operation. The terms are usually either variables or functions that are combined with an operator to evaluate to a string or numeric result.
What are operators and expressions?
Expressions perform specific actions, based on an operator, with one or two operands. An operand can be a constant, a variable or a function result. Operators are arithmetic, logical, and relational. As with C, some operators vary in functionality according to the data type of the operands specified in the expression.
