After the two players are separated, Alice is randomly assigned one row of the table and asked to fill it with plus and minus signs. Similarly, Bob is randomly assigned one column of the table and asked to fill it with plus and minus signs. The players are subject to the following requirement: Alice must fill in her row such that there is an even number of minus signs in that row. Furthermore, Bob must fill in his column such that there is an odd number of minus signs in that column.

For example, the formula for sulfuric acid is + . In physics, the use of plus and minus signs for different electrical charges was introduced by Georg Christoph Lichtenberg. In the International Phonetic Alphabet, subscripted plus and minus signs are used as diacritics to indicate advanced or retracted articulations of speech sounds. The minus sign is also used as tone letter in the orthographies of Dan, Krumen, Karaboro, Mwan, Wan, Yaouré, Wè, Nyabwa and Godié.

As well as the normal mathematical usage, plus and minus signs may be used for a number of other purposes in computing. Plus and minus signs are often used in tree view on a computer screen—to show if a folder is collapsed or not. In some programming languages, concatenation of strings is written , and results in . In most programming languages, subtraction and negation are indicated with the ASCII hyphen-minus character, .

Dylan is not case sensitive. Dylan's lexical syntax allows the use of a naming convention where hyphen-minus signs are used to connect the parts of multiple- word identifiers (sometimes called "lisp-case" or "kebab case"). This convention is common in Lisp languages but cannot be used in programming languages that treat any hyphen-minus that is not part of a numeric literal as a single lexical token, even when not surrounded by whitespace characters. Besides alphanumeric characters and hyphen-minus signs, Dylan allows certain non-alphanumerical characters as part of identifiers.

Some elementary teachers use raised plus and minus signs before numbers to show they are positive or negative numbers. For example, subtracting −5 from 3 might be read as "positive three take away negative 5", and be shown as : becomes , or even as : becomes .

Before performing a Yates analysis, the data should be arranged in "Yates order". That is, given k factors, the kth column consists of 2(k - 1) minus signs (i.e., the low level of the factor) followed by 2(k - 1) plus signs (i.e., the high level of the factor).

In the algebraic notation used to record games of chess, the plus sign is used to denote a move that puts the opponent into check, while a double plus is sometimes used to denote double check. Combinations of the plus and minus signs are used to evaluate a move (+/−, +/=, =/+, −/+).

In grading systems (such as examination marks), the plus sign indicates a grade one level higher and the minus sign a grade lower. For example, ("B minus") is one grade lower than . In some occasions, this is extended to two plus or minus signs (e.g., being two grades higher than ).

Restricting to changes of coordinates with positive Jacobian determinant is possible on orientable manifolds, because there is a consistent global way to eliminate the minus signs; but otherwise the line bundle of densities and the line bundle of n-forms are distinct. For more on the intrinsic meaning, see density on a manifold.

The plus and minus signs, and , are mathematical symbols used to represent the notions of positive and negative as well as the operations of addition and subtraction (which correspond to sum and difference, respectively). Their use has been extended to many other meanings, more or less analogous. Plus and minus are Latin terms meaning "more" and "less", respectively.

Asiputu was unusual for that period in history because asipu did not claim to foresee the future but approached the construction of advice through a repeatable, consistent process of identifying important dimensions of the problem, considering alternatives and collecting data. The practice was similar to modern balanced methodology in hazards risk management where alternatives were marked with plus or minus signs depending on favorability.

After they are separated, communication between them is not possible. The game requires that Alice fill in one row, and Bob one column, of a 3x3 table with plus and minus signs. Before the game begins, Alice does not know which row of the table she will be required to fill in. Similarly, Bob does not know which column he will be required to fill in.

The Danish dentist Victor Haderup devised a variation of the Palmer notation where the (┘└ ┐┌) symbols are replaced by plus/minus signs, which can either be placed in front or behind the number. A plus (+) indicates upper position while minus (−) indicates lower. When the sign is in front of the number, it indicates left while after it indicates right. For instance −6 indicates the 6th lower left tooth, i.e.

Either both players win, or both players lose. If Alice and Bob place the same sign in the cell shared by their row and column, they win the game. If they place opposite signs, they lose the game. Note that both players place all their plus and minus signs simultaneously, and neither player can see where the other player has placed their signs until the game is finished.

In chemistry, superscripted plus and minus signs are used to indicate an ion with a positive or negative charge of 1 (e.g., NH). If the charge is greater than 1, a number indicating the charge is written before the sign (as in SO). The minus sign is also used, in place of an en dash, for a single covalent bond between two atoms as in the skeletal formula.

The energy carried by the particle in the propagator can even be negative. This can be interpreted simply as the case in which, instead of a particle going one way, its antiparticle is going the other way, and therefore carrying an opposing flow of positive energy. The propagator encompasses both possibilities. It does mean that one has to be careful about minus signs for the case of fermions, whose propagators are not even functions in the energy and momentum (see below).

The E8 root system also contains a copy of A8 (which has 72 roots) as well as E6 and E7 (in fact, the latter two are usually defined as subsets of E8). In the odd coordinate system, E8 is given by taking the roots in the even coordinate system and changing the sign of any one coordinate. The roots with integer entries are the same while those with half-integer entries have an odd number of minus signs rather than an even number.

The levels of a factor are commonly coded as +1 for the higher level, and −1 for the lower level. For a three-level factor, the intermediate value is coded as 0\. To save space, the points in a two-level factorial experiment are often abbreviated with strings of plus and minus signs. The strings have as many symbols as factors, and their values dictate the level of each factor: conventionally, - for the first (or low) level, and + for the second (or high) level.

They designate the day and hour of the operation when the day and hour have not yet been determined, or where secrecy is essential. For a given operation, the same D-Day and H-Hour apply for all units participating in it. When used in combination with numbers, and plus or minus signs, these terms indicate the point of time preceding or following a specific action. Thus, H−3 means 3 hours before H-Hour, and D+3 means 3 days after D-Day.

The commercial minus sign is a typographical and mathematical symbol used in commercial and financial documents in some European languages, in specific contexts. In some commercial and financial documents, especially in Germany and Scandinavia, the commercial minus sign is used to signify a negative remainder of a division operation. The symbol is also used in the margins of letters to indicate an enclosure, where the upper point is sometimes replaced with the corresponding number. The Uralic Phonetic Alphabet uses commercial minus signs to denote borrowed forms of a sound.

The plus and minus signs note the particle's chirality. A schematic (bottom) shows the way Weyl fermions inside a crystal can be thought as monopole and antimonopole in momentum space. (Image art by Su-Yang Xu and M. Zahid Hasan) On 16 July 2015 the first experimental observations of Weyl fermion semimetal and topological Fermi arcs in an inversion symmetry-breaking single crystal material tantalum arsenide (TaAs) were made. Both Weyl fermions and Fermi arc surface states were observed using direct electronic imaging using ARPES, which established its topological character for the first time.

The plus and minus signs indicated that a letter had to be added or removed, respectively, without changing the order of the others. Answers could be three, four, or five letters in length. Buzzing-in also stopped a randomiser that determined the value of the word: £10, £20, £40 (£30 in the last two series), or "Tie," which if hit by the second- or third-place contestant, immediately increased their score to match that of the leader. An incorrect answer gave the opponents a chance to buzz-in.

The chemical formula for a molecule uses one line of chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, and plus (+) and minus (−) signs. These are limited to one typographic line of symbols, which may include subscripts and superscripts. A compound's empirical formula is a very simple type of chemical formula. It is the simplest integer ratio of the chemical elements that constitute it. For example, water is always composed of a 2:1 ratio of hydrogen to oxygen atoms, and ethanol (ethyl alcohol) is always composed of carbon, hydrogen, and oxygen in a 2:6:1 ratio.

An especially important one is the "spiral sign", consisting of a column of different combinations of four or five plus or minus signs bracketed by repeat marks. At this sign, the performer is to repeat the previous event several times, transposing it each time in all parameters, and attempt to transcend not only previous limits reached in the piece, but also to go beyond the limitations of the instrument/voice itself. In doing this, the performer is encouraged to employ visual and theatrical possibilities . Because there are only seven "spiral" signs altogether, not every section contains one of them .

In APL a raised minus sign (Unicode U+00AF) is used to denote a negative number, as in . While in J a negative number is denoted by an underscore, as in . In C and some other computer programming languages, two plus signs indicate the increment operator and two minus signs a decrement; the position of the operator before or after the variable indicates whether the new or old value is read from it. For example, if x equals 6, then increments x to 7 but sets y to 6, whereas would set both x and y to 7.

In fact τ is reversion (the antiautomorphism induced by the identity on V) for m even, and conjugation (the antiautomorphism induced by minus the identity on V) for m odd. These two antiautomorphisms are related by parity involution α, which is the automorphism induced by minus the identity on V. Both satisfy τ(ξ) = −ξ for ξ in so(n,C). When n = 2m, the situation depends more sensitively upon the parity of m. For m even, a weight λ has an even number of minus signs if and only if −λ does; it follows that there are separate isomorphisms B±: S± → S±∗ of each half-spin representation with its dual, each determined uniquely up to scale.

As an orthographic concept, the hyphen is a single entity. In terms of character encoding and display, the entity is represented by any of several characters and glyphs (including hard hyphens, soft or optional hyphens, and non-breaking hyphens), depending on the context of use (discussed below). Although hyphens are not to be confused with en dashes and minus signs, there are some overlaps in usage (in which either a hyphen or an en dash may be acceptable, depending on user preference, as discussed below) and in informal typing (which often uses the same character called a "hyphen-minus" to represent any of the hyphen, the minus sign and the en dash, see below).

Each plus, minus, or equal sign indicates that, upon repetition of an event, the performer is to increase, decrease, or maintain the same level in one of four musical dimensions (or "parameters"): overall duration of the event, number of internal subdivisions, dynamic level, or pitch register/range. It is up to the performer to decide which of these dimensions is to be affected, except that vertically stacked signs must be applied to different parameters. Despite this, a large number of plus signs (for example) will result in successive events becoming longer, more finely subdivided, louder, and either higher or wider in range; a large number of minus signs will produce the reverse effect .

The hyphen-minus is a general-purpose character that attempts to fulfil several roles, and wherever optimal typography is desired, the formal hyphen, minus, or other symbol should be used instead. For example, compare (minus) and (hyphen-minus); in most fonts the hyphen-minus will not have the optimal width, thickness, or vertical position, whereas the minus character will. However, the Unicode hyphen is inconvenient to enter on most keyboards, so the hyphen-minus character remains very common. It is often used instead of dashes or minus signs in situations where the preferred characters are unavailable (such as ASCII-only text), where the preferred characters take effort to enter (via dialog boxes or multi-key, unmemorable keyboard shortcuts), or when the writer is unaware of the distinction.

Fudge dice A number of games including the original Ghostbusters role- playing game, the Storyteller system, and Fantasy Flight Games' Star Wars Roleplaying Games use a system where a dice pool consisting of an indicated number of dice are rolled and the total number of dice which meet a fixed condition are recorded as the result. For example, Vampire: the Requiem has players roll a pool of ten sided dice and note the number that come up as 8 or higher as "successes". Some companies produce custom dice, marked with successes and failures, for use in games which use this mechanic. The Fudge role-playing system uses a set of dice which are each marked with minus signs, plus signs and blank sides, meaning −1, +1 and 0 respectively.

Each plus, minus, or equal sign indicates that, upon repetition of an event, the performer is to increase, decrease, or maintain the same level in one of four musical dimensions (or "parameters"): overall duration of the event, number of internal subdivisions, dynamic level, or pitch register/range. It is up to the performer to decide which of these dimensions is to be affected, except that vertically stacked signs must be applied to different parameters . Despite this indeterminacy, a large number of plus signs (for example) will result in successive events becoming longer, more finely subdivided, louder, and either higher or wider in range; a large number of minus signs will produce the reverse effect . To the signs previously used in Prozession and Kurzwellen, Stockhausen adds a dozen new ones.

Some of the same methods were described in other manuscripts predating the Summa (such as the 1458 Della mercatura e del mercante perfetto by Benedetto Cotrugli), but none was published before Pacioli's work, and none achieved the same wide influence. The work's role in standardizing and disseminating professional bookkeeping methods has earned Pacioli a reputation as the "father of accounting". The book also marks the beginning of a movement in sixteenth-century algebra toward the use of logical argumentation and theorems in the study of algebra, following the model of classical Greek geometry established by Euclid. It is thought to be the first printed work on algebra, and it includes the first printed example of a set of plus and minus signs that were to become standard in Italian Renaissance mathematics: 'p' with a tilde above (p̄) for "plus" and 'm' with a tilde (m̄) for minus.

In the so-called even coordinate system, E8 is given as the set of all vectors in R8 with length squared equal to 2 such that coordinates are either all integers or all half- integers and the sum of the coordinates is even. Explicitly, there are 112 roots with integer entries obtained from : \left(\pm 1,\pm 1,0,0,0,0,0,0\right)\, by taking an arbitrary combination of signs and an arbitrary permutation of coordinates, and 128 roots with half-integer entries obtained from : \left(\pm\tfrac12,\pm\tfrac12,\pm\tfrac12,\pm\tfrac12,\pm\tfrac12,\pm\tfrac12,\pm\tfrac12,\pm\tfrac12\right) \, by taking an even number of minus signs (or, equivalently, requiring that the sum of all the eight coordinates be even). There are 240 roots in all. E8 2d projection with thread made by hand The 112 roots with integer entries form a D8 root system.

It is easy to prove that in the classic formulation of this game, there is no strategy (Nash equilibrium or otherwise) which allows the players to win the game with probability greater than 8/9. If Alice and Bob meet before the game begins and exchange information, this will not impact the game in any way; the best the players can do is still win with probability 8/9. The reason why the game can only be won with probability 8/9 is that a perfectly consistent table does not exist: it would be self-contradictory, with the sum of the minus signs in the table being even based on row sums, and being odd when using column sums, or vice versa. As a further illustration, if they use the partial table shown in the diagram (supplemented by a −1 for Alice and a +1 for Bob in the missing square) and the challenge rows and columns are selected at random, they will win 8/9 of the time.
