		Mathematical operators represent a wide variety of styles of presentation, and so require a wide variety of conventions for two-dimensional input of mathematical expressions.
		This operation removes parentheses around the current expression when its parent element is an application of the same associative operator, with the effect that the child elements of the current expression become child elements of the parent element.
		This operation inserts a new column to the left of the column containing the current expression, moving the expression cursor to the new element in the same row as the current expression.

		The division operator, when one integer is divided by another, results in the whole number of times the second number divides into the first (the result when the quotient is a whole number and a remainder).
		Mathematical operators used in combination with the assignment operator, "=", can be used to reassign a value to a variable by performing a mathematical operation on it, and replacing the original value with the result (e.g., num += 6 is the same as num = num + 6).
		When you have a number of operators in the same statement, the order in which the operations are processed is dictated by the rules of precedence, such as division and multiplication being performed before addition and subtraction.

	Information Technology: Web Central - JavaScript Reference - Operators and Conditionals (Site not responding. Last check: 2007-10-14)
		Mathematical operators are used to perform the basic mathematical functions in JavaScript.
		There are two types of mathematical operators that are unary operators (this means they work on only one operand).
		These operators display different types of behavior depending on which side of the operand they are on and can be used in conjunction with assignment operators.

	Operator - Wikipedia, the free encyclopedia
		For instance, in linear algebra an "operator" is a linear operator.
		Operators are often in practice just partial functions, a common phenomenon in the theory of differential equations since there is no guarantee that the derivative of a function exists.
		Three main operators are key to vector calculus, the operator ∇, known as gradient, where at a certain point in a scalar field forms a vector which points in the direction of greatest change of that scalar field.

	Avadikiran's Online - C in 21 Days -- Ch 4 -- Statements, Expressions, and Operators
		C's relational operators are used to compare expressions, asking questions such as, "Is x greater than 100?" or "Is y equal to 0?" An expression containing a relational operator evaluates to either true (1) or false (0).
		The compound operators provide a convenient shorthand, the advantages of which are particularly evident when the variable on the left side of the assignment operator has a long name.
		Operators are C symbols that instruct the computer to perform an operation on one or more expressions.

		This is called a file operator because it sends information about the content of the stack to the standard output file which is the screen by default.
		After the operation is done only the result remains in the operand stack as a new element.

	The JavaScript Diaries: Part 3 - webreference.com
		The term "operator" is derived from the action that is performed on a piece of data.
		The action is called an "operation:" the tool used to perform the operation is called an "operator." The values (i.e., numbers assigned to a variable) that are used in the operation are called "operands" (I'll use these two terms — value and operand — interchangeably).
		This operator is used to subtract the value on the right of the operator from the value on the left, i.e., "7 - 2" would read "seven minus two".

		An operator is a symbol that instructs C to perform some operation, or action, on one or more operands.
		The operation performed is to add one to or subtract one from the operand.

		Mathematical expressions involving reals will always see if the answer can be stored as a fixed real instead of as a long real.

		This is because when M is prime the operations are being performed on an integer ring, and for every element in that ring there is a unique inverse.

		The operators are particularly useful for the analysis of binary images and common usages include edge detection, noise removal, image enhancement and image segmentation.
		The two most basic operations in mathematical morphology are erosion and dilation.
		Both of these operators take two pieces of data as input: an image to be eroded or dilated, and a structuring element (also known as a kernel).

		Using the exponentiation operator (^), is the same as raising a number to a certain power.

		They can be constructed using operators (mathematical and logical operators, internal-array and functions verbs, and function procedures), as well as operands (real, logical, and literal constants, and array, scalar, pointer, keyword, and string adverbs.)
		A reference to an element of an array adverb is the name of the adverb followed by the indices of the desired array element enclosed in parentheses and separated by commas.
		While UniPOPS understands algebraic, Polish, and reverse Polish notation for mathematical and logical expressions, it is best to enter expressions in algebraic form, similar to writing an expression in FORTRAN or C. As in FORTRAN and C, it is highly recommended that one uses opening and closing parentheses to order and arrange the expression.

	Operators and Functions
		Operators operate on either a single value or a pair of values.
		Many operators, while invoked with the same keyword or character symbol, will have different effects depending on the data types to which they are applied.
		Mathematical operators affect one or two values, perform a mathematical operation, and return a value of a numeric data type.

	Mathematical Notation: Past and Future
		In the early 1900s mathematical logicians talked quite a bit about different layers in well-formed mathematical expressions: variables inside functions inside predicates inside functions inside connectives inside quantifiers.
		Now I have to tell you that I had always assumed that mathematical notation was too haphazard to be used as any kind of thing that a computer could reasonably interpret in a rigorous way.
		Neil Soiffer had spent quite a number of years working on editing and interpreting mathematical notation, and when he joined our company in 1991, he started trying to convince me that one really could work with mathematical notation in a reasonable way, for both output and input.
