An expression is a group of literal and variables which are organized in a structured format using operators.
Expressions are made up of a collection of mathematical, comparison, bit-wise and logical operators as well as literal values and ASP variables which are placed together for evaluation by the ASP Interpreter.
Whereas mathematical expressions are used to manipulate numbers, logical operators are used to work with the two boolean values "true" and "false".

Thus an expression represents a function whose inputs are the values assigned the free variables and whose output is the resulting value of the expression.
Two expressions are said to be equivalent if, for each combination of values for the free variables, they have the same output, i.e., they represent the same function.
Expressions and their evaluation were formalised by Alonzo Church and Stephen Kleene in the 1930s in their lambda calculus.

  Expression (mathematics) - Wikipedia, the free encyclopedia
For a given combination of values for the free variables, an expression may be evaluated, although for some combinations of values of the free variables, the expression may be undefined.
Thus an expression represents a function whose inputs are the values assigned the free variables and whose output is the resulting value of the expression.
Expressions and their evaluation were formalised by Alonzo Church and Stephen Kleene in the 1930s in their lambda calculus.

 Expression (programming) - Wikipedia, the free encyclopedia
An expression in a programming language is a combination of values, variables, operators, and functions that are interpreted (evaluated) according to the particular rules of precedence and of association for a particular programming language, which computes and then produces (returns, in a stateful environment) another value.
As in mathematics, the expression is (or can be said to have) its evaluated value; the expression is a representation of that value.
Expressions may or may not have side-effects and lose the referential transparency with them.

When the Hellenic civilization declined, Greek mathematics (and the rest of Greek science) was kept alive by the Arabs, especially in the scientific academy at the court of the caliphs of Baghdad.
In the 17th century the focus of mathematical activity moved to France and Britain though continuing with the major themes of Italian mathematics: improvements in methods of calculation, development of algebraic symbolism, and the development of mathematical methods for use in physics and astronomy.
Traditionally the subject of mathematics is divided into arithmetic, which studies numbers, geometry, which studies space, algebra, which studies structures, analysis, which studies infinite processes (in particular, calculus), and probability theory and statistics, which study random processes.

The two-dimensional structure of mathematical notation means that when you are using Zed, you will need to think about what you are creating in new ways—both in terms of how the math appears on the page, and in terms of how the math is built up out of operators and arguments.
In fact, the presentation markup for the two expression is almost identical, except for the insertion of a few references to the entity invisible times (andit;), and for the use of versus .
While these two expressions are equivalent with the usual interpretation of the operators involved, Zed maintains the structural distinction between the two, and so the presentation of the two forms is quite different.

 Math Markup Language (Chapter 4)
When mathematical semantics are inferred from presentation markup, processing agents must either be quite sophisticated, or they run the risk of inferring incomplete or incorrect semantics when irregular constructions are used to achieve a particular aural or visual effect.
It is always possible to apply arbitrary expressions as if they were functions and to infer their functional properties directly from that usage as was done in the previous section.
A number of common mathematical constructions involve additional data which is either implicit in conventional notation, such as a bound variable, or thought of as part of the operator rather than an argument, as is the case with the limits of a definite integral.
