unreferenced date June 2010 Infobox notation logo File Infix dia.svg 125px Infix notation is the common arithmetic and logical formula notation, in which operator mathematics operator s are written infix style between the operand s they act on e.g. 2 2 . It is not as simple to parsing parse by computers as Polish notation prefix notation e.g. 2 2 or reverse Polish notation postfix notation e.g. 2 2 , but many programming language s use it due to its familiarity. In infix notation, unlike in prefix or postfix notations, Bracket Parentheses parentheses surrounding groups of operands and operators are necessary to indicate the intended order in which operations are to be performed. In the absence of parentheses, certain precedence rules determine the order of operations . Infix notation may also be distinguished from Function mathematics function notation, where the name of a function suggests a particular operation, and its arguments are the operands. An example of such a function notation would be S 1,3 in which the function S denotes addition S 1,3 1 3 4 .

Physics often deals with classical models where the dynamical variables are a collection of functions sup sup sub sub over a d dimensional space spacetime manifold M where is the flavor particle physics flavor index. This involves functional mathematics functional s over the s, functional derivative s, functional integral s, etc. From a functional point of view this is equivalent to working with an infinite dimensional smooth manifold where its points are an assignment of a function for each , and the procedure is in analogy with differential geometry where the coordinates for a point x of the manifold M are sup sup x .

Nuclear notation is formed by writing an List of elements by symbol elemental symbol preceded by a subscript indicating its atomic number number of proton s and a superscript indicating its mass number number of nucleon s . For example, carbon 12 has an atomic number of 6 and a mass number of 12 and would thus be written as Nuclide Carbon 12 . If the isotope is in a metastable isomer metastable state , an m can be added to the mass number. For example technetium 99m can be written as Nuclide Technetium 99m .

The Schoenflies or Sch nflies notation , named after the Germans German mathematician Arthur Moritz Schoenflies , is one of two conventions commonly used to describe point group s.

A point group in the Schoenflies convention is completely adequate to describe the symmetry of a molecule this is sufficient for spectroscopy. The Hermann Maunguin notation is able to describe the space group of a crystal lattice, while the Schoenflies notation isn t. Thus the Hermann Mauguin notation is used in crystallography . Symmetry elements Symmetry elements are denoted by i for centers of inversion, C for proper rotation axes, for mirror planes, and S for improper rotation axes rotation reflection axes . C and S are usually followed by a subscript number abstractly denoted n denoting the order of rotation possible. By convention, the axis of proper rotation of greatest order is defined as the principal axis. All other symmetry elements are described in relation to it. A vertical mirror plane containing the principal axis is denoted sub v sub a horizontal mirror plane perpendicular to the principal axis is denoted sub h sub .

Unreferenced date June 2008 Subtractive notation is an early form of positional notation used with Roman numerals as a shorthand to replace four or five characters in a numeral representing a number with usually just two characters. Using subtractive notation the numeral VIIII becomes simply IX. LXXXXVIII would become IIC, which is invalid in Roman numerals though. Without subtractive notation, XIV represents the same number as XVI 16 in Arabic numerals . With the introduction of subtractive notation, XIV 14 no longer represents the same number as XVI but rather is an alternate way of writing XIIII. By encoding information about the number into the order of the numerals, subtractive notation transformed the Roman numeral system from a variation of a unary numeral system which used alphabetic characters to represent groupings of tally marks a position independent counting system . This form of notation closely follows Latin language usage, in which the number 18 is pronounced as duodeviginti , meaning two deducted from twenty duo de viginti , and 19 is pronounced undeviginti , meaning one deducted from twenty un de viginti . The very positive advantage of subtractive notation is the reduction of counters needed on an Roman abacus abacus , the calculating devices used by the Romans, and those before them for thousands of years. They did not do arithmetic with their written numerals. They used their numerals only for recording the results of calculations on an abacus. Reduction of counters is also why they used intermediate 5 values, i.e. V, L, and D. The number of counters needed to represent IIIIIIIII, VIIII, and IX are 9, 5, and 2. Subtractive notation reflected the counter positions on an abacus with positive and negative counters on opposite sides of a median line.

unreferenced date January 2008 Caret notation is a notation for unprintable control character s in ASCII ASCII encoding . The notation consists of a caret followed by a capital letter this digraph stands for the ASCII code that has the numerical value equivalent to the letter s numerical value. For example the end of transmission character EOT character with a value of 4 is represented as tt D tt because D is the 4th letter in the alphabet. The null character NUL character with a value of 0 is represented as tt tt At sign is the ASCII character before A . The Delete character DEL character with the value 127 is usually represented as tt ? tt , because the ASCII ? is before and 1 is the same as 127 if masked to 7 bits. For a complete list of caret notation, see C0 and C1 control codes . Many computer systems allow you to enter a control character by holding down Control key Ctrl and pressing the letter used in the caret notation. This is practical, because many control characters e.g. EOT cannot be entered directly from a keyboard. Although there are many ways to represent control characters, this correspondence between notation and typing makes the caret notation suitable for many applications. Caret notation is used in many programs, particularly Unix terminal drivers and text file viewers such as more command more and Less Unix less . Alternate notations Acorn Computers Acorn operating systems for the Acorn Atom Atom , BBC Micro , Acorn Archimedes Archimedes and later RISC OS machines use the vertical bar character tt tt in place of the caret. e.g. tt M tt pronounced control M is the carriage return character, ASCII 13. tt tt is the vertical bar character code 124, tt ? tt is character 127 as above and tt tt adds 128 to the code of the following character, so tt ? tt is character code 128 127 255.
