 An [[Expression|expression]] is a complex mathematical construction that allows more advanced use of resources available to pistons. You can use an expression to calculate data based on input, such as finding out the dew point, or the average of a set of values, or the minimum value, or write a string in a desired format, etc.

In essence, a piston is an organized collection of basic elements, each element having its own role in the structure. The basic elements that work together are described below:

-==Condition==
+===Condition===
 Most decisional statements rely on ''conditions'' to alter the execution logical flow. A condition is a collection of one or more comparisons (described below). It returns a boolean (true/false) value that is then used by the statement to direct the flow.
-==Condition Group==
+===Condition Group===
 A condition group is a collection of conditions, grouped together with a logical operator (and, or, xor, etc.)

+===Restriction Group===
 A restriction group is a collection of restrictions, grouped together with a logical operator (and, or, xor, etc.)
-==Comparison==
+===Comparison===
 A comparison is a logical operation that involves one operator and one to three operands. The operator is applied to the operands and the result is returned as a boolean (true/false) value. It is the core evaluation block of webCoRE. When a comparison is performed, all the operands are evaluated and then compared using the operator.
-==Operator==
+===Operator===
 An operator is a mathematical symbol or conditional construction that determines the type of operation to be performed. Some mathematical operators are ''+'' (addition), ''-'' (subtraction), ''%'' (modulus), ''&'' (logical AND), ''|'' (logical OR), etc. Some logical operators include ''is''/''is equal'' (equality), ''is less than'', ''is greater than'', ''is different than'', etc.

In essence, a piston is an organized collection of basic elements, each element having its own role in the structure. The basic elements that work together are described below:

		+	==Statement==
		+	A statement is the main building block of a piston script. There are two kinds of statements: ''executive'' and ''decisional''.

		+	==Executive statements==

		+
		+	==Operand==
		+	An operand is a generic term for a value that is used in a comparison. webCoRE defines several types of operands:
		+	* Physical Device
		+	:A physical device operand represents one or more devices paired with an attribute. When evaluated, the attribute of the selected device is returned
		+	* Virtual Device
		+	:A virtual device operand represents the current state/value of a virtual device. Generally, virtual devices are entities that do not exist physically. Examples of virtual devices are Time, Location Mode, Smart Home Status, IFTTT, AskAlexa macros, EchoSistant profiles, etc.
		+	* Variable
		+	:A variable operand points to a variable whose value is then returned as part of the evaluation.
		+	* Value
		+	:A value operand is the most basic of operands, usually consisting of a constant string, integer, time, depending on the operand data type. Values are capable of containing expressions, simply include them inside curly brackets { }. Examples of values are 'on', 'Away', 'Everybody left', 77.0, 'The location mode is {$locationMode}'
		+	* [[Expression]]
		+	:An expression operand is the most advanced of operands, allowing for more complicated calculations to be performed. They allow mathematical operations, logical operations, functions, concatenation, etc. Some examples of expressions are ''1 + 2'', ''$hour * 60 + $minute'', ''[$currentEventDevice:switch]''.
		+	* Argument
		+	:An argument operand is a way of retrieving data that has been passed to the piston through the various execution channels. For example, an IFTTT trigger can pass data to a piston, and that data can be read via the argument operands.
