Mathematica Tutorial: Notebooks And Documents - Wolfram Research

In traditional mathematical exposition, there are many tricks for replacing chunks of text by58 Notebooks and Documentsthat Mathematica expressions can represent not only mathematical objects but also procedures,algorithms, graphics, and interfaces increases greatly the extent to which chunks of text can bereplaced by shorter and more precise material.Named CharactersMathematica provides systemwide support for a large number of special characters. Each charac -ter has a name and a number of shortcut aliases. They are fully supported by the standardMathematica fonts.Interpretation of CharactersThe interpretations given here are those used in StandardForm and InputForm. Most of theinterpretations also work in TraditionalForm.You can override the interpretations by giving your own rules for MakeExpression.Letters and letter-like formsused in symbol namesInfix operatorse.g. x⊕ yPrefix operatorse.g. Ÿ xPostfix operators e.g. x!Matchfix operatorse.g. Xx\Compound operatorse.g. Ÿ f „ xRaw operatorsSpacing charactersStructural elementsUninterpretable elementsoperator characters that can be typed on an ordinarykeyboardinterpreted in the same way as an ordinary spacecharacters used to specify structure; usually ignored ininterpretationcharacters indicating missing informationTypes of characters.The precedences of operators are given in "Operator Input Forms".Infix operators for which no grouping is specified in the listing are interpreted so that for examplex⊕ y⊕z becomes CirclePlus@x, y, zD.Naming Conventions
