Some people refer to the - as a hyphen or a minus sign. They appear in the form of double quotation marks " " and single quotation marks ' '. The single quotation marks usually indicate a quotation within a normal quotation. Punctuation Marks with Symbols, Explanations, and Examples this page includes a presentation of the punctuation marks or symbols that are in general use in English writing.

One of a pair of symbols or together, [ ]they are used in writing or mathematics for showing that the piece of information or set of numbers between them can be considered separately. A punctuation mark :which is used after a word introducing a quotation, an explanation, an example, or a series; and that is often presented after the salutation in a business letter; such as, Dear Mr. A common markthat is presented as an indication of a separation of ideas or of elements within the structure of a sentence; including, a pause between parts of a sentence or between elements in a list.

A grammatical dash —shown between parts of a compound word or between the syllables of a word when the word is divided at the end of a line of text. A mark, or a series of marks. A symbol,! A mark, -that is used between the parts of a compound word, a name, or between the syllables of a word; especially, when it is divided at the end of a line of text.

Either of a pair of brackets ; especially, round brackets, and used to enclose parenthetical material in a text. A punctuation. This symbol " consists of either of a pair of punctuation marks used to mark the beginning and the end of a passage by another person and repeated word for word, and it also indicates meanings and the unusual or doubtful status of a word.

This punctuation mark ; connects independent clauses and indicates a closer relationship between clauses than a period does and is followed by an initial lower-case letter unless there is a proper noun existing after the semicolon.

The simplest shapes are found in nature and are used by many different cultures around the world to represent a wide variety of meanings. Shape symbols range from common circles and squares and triangles to more obscure shapes such as unicursal hexagrams. The 6th century BCE Greek philosopher and mathematician Pythagoras believed that geometry was the rational understanding of God, man, and nature: Many of the shape meanings in western philosophies arise from his writings.

Circles are among the oldest of geometric symbols, and commonly represent unity, wholeness, and infinity. Pythagoras called the circle "monad," the most perfect of creative forms, without beginning or end, without sides or corners.

He associated the circle with the number 1 and the practice of monotheism. In the Zen Buddhist philosophy, a circle stands for enlightenment and perfection in unity with the primal principles. Circles are sometimes symbols of the Judeo-Christian God and sanctity, appearing as haloes. In Chinese symbology, the circle represents the heavens. Circles are also often seen as protective symbols. In occult practices, standing within a circle shields people from supernatural dangers or outside influences.

Circles can also represent containing, keeping what is inside from been released. First attested in the New Kingdom Egypt in the 10thth century BCE, the ouroboros represents the cycle of rebirth, completion, unification of polarities, regeneration, and eternity. Ouroboros is also found in Aztec and Norse mythologies. The astrological symbol of the sun is a circle with a dot in the middle. The same symbol is used to represent gold, which is strongly associated with the sun.

The element of spirit, seen as an element equal to or superior to the physical elements of fire, air, water, and earth, is commonly represented by a circle. A spiral is a curve that starts as a point in the center, and curls around to a large circle; concentric circles are related symbols, consisting of a set of nested circles. Found in nature such as nautilus shells, spirals are some of the oldest geometric shapes, found carved into Neolithic passage tombs in the United Kingdom, carved on rock art around the world, and as part of the geoglyphic Nazca lines in Peru.

Anthropologists and others typically associate spirals and concentric rings with shamanism and the achievement of altered states of consciousness. In Western society, equilateral triangles most often have Christian meanings in religious contexts. Because the Christian God is a trinity—Father, Son, and Holy Ghost united in a single godhead—he is commonly represented by a triangle. Pythagoras associated the number 3 with triangles, which is meaningful to many groups.

Triangles and other three-part symbols may present such concepts as past, present, and future or spirit, mind, and body. Some occultists use the triangle as a summoning symbol. At the culmination of a ritual, the desired being is expected to appear within a triangle inscribed upon the floor. The occultist often performs rituals from the protection of a circle.

Point-Up and Point-Down Triangles. The orientation of a triangle can be important to its meaning. Point-up triangles represent a strong foundation or stability.

Earth and water symbols are formed from point-up triangles; pointing upward stands for the ascent to heaven. The point-up triangle can also represent male energy, and fire and air are masculine elements. The point-down triangle can represent female energy, and water and earth are feminine elements. Symbols for air and fire are formed from point-down triangles; point-down triangles can represent the descent into the physical world.

When paired and presented as point-to-point, triangles represent sexual union and the principle of harmony. The cross is best known in its Christian context as a symbol of sacrifice and salvation referring to Jesus' death by crucifixion. The cross has numerous other religious meanings, most of which reflect groups of four, corresponding to the four points on the cross.My stats textbook gives Greek symbols left and right without saying how they're pronounced.

When doing research in psychology you are sometimes required to study new statistical or mathematical techniques on your own. However, mathematical books rarely tell you how to pronounce the mathematical symbols. And even if you know how to pronounce the symbols in isolation, this does not guaranty that you can pronounce a mathematical expression made up of multiple symbols.

Being able to read mathematical notation is a basic first step in aiding memory and conceptual understanding. The following links provide resources on reading mathematical symbols and provide a good reference if you encounter symbols and expressions with which you are not familiar. It covers many major branches of mathematics such as logic and set theory, geometry, statistics, calculus, and linear algebra. It is the most comprehensive guide that I have found with around pages and around symbols with pronunciation.

I'd recommend studying all the symbols if mathematical pronunciation is an issue for you.

Geometric Shapes and Their Symbolic Meanings

The symbols are distributed over many pages making it a little difficult to look up a single symbol of interest. Also, when a choice exists, the guide often chooses a more verbose and less ambiguous form of pronunciation. This emphasis on unambiguous verbal communication is sometimes more than required when verbalising the symbols in your head or when verbalising symbols in a context where the actual symbolic math is also displayed.

By jeromyanglim on Friday, May 29, Labels: mathematics. Hu Junfeng September 14, at PM. Anonymous June 6, at AM. Anonymous August 22, at AM.A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical objectan action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.

As formulas are entierely constitued with symbols of various types, many symbols are needed for expressing all mathematics. The most basic symbols are the decimal digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9and the letters of the Latin alphabet.

The decimal digits are used for representing numbers through the Hindu—Arabic numeral system. Historically, upper-case letters were used for representing points in geometry, and lower-case letters were used for variables and constants.

Exhaustive List of Mathematical Symbols and Their Meaning

Letters are used for representing many other sort of mathematical objects. As the number of these sorts has dramatically increased in modern mathematics, the Greek alphabet and some Hebrew letters are also used.

In mathematical formulasthe standard typeface is italic type for Latin letters and lower-case Greek letters, and upright type for upper case Greek letters.

The use of letters as symbols for variables and numerical constants is not described in this article.

For these uses, see Variable mathematics and List of mathematical constants. Letters are not sufficient for the need of mathematicians, and many other symbols are used. Some take their origin in punctuation marks and diacritics traditionally used in typography. Normally, entries of a glossary are structured by topics and sorted alphabetically.

This is not possible here, as there is no natural order on symbols, and many symbols are used in different parts of mathematics with different meanings, often completely unrelated. Therefore some arbitrary choices had to be done, which are summarized below. The article is split in sections that are sorted by increasing level of technicality. That is, the first sections contain the symbols that are encountered in most mathematical texts, and that are supposed to be known even by beginners.

On the other hand, the last sections contain symbols that are specific to some area of mathematics and are ignored outside these areas. Most symbols have multiple meanings that are generally distinguished either by the area of mathematics where there are used or by their syntaxthat is, by their position inside a formula and the nature of the other parts of the formula that are close to them.

As readers may be not aware of the area of mathematics to which is related the symbol that they are looking for, the different meanings of a symbol are grouped in the section corresponding to their most common meaning.

When the meaning depends on the syntax, a symbol may have different entries depending on the syntax. Most symbols have two printed versions. They can be displayed as Unicode characters, or in LaTeX format. With the Unicode version, using search engines and copy-pasting are easier. On the other hand, the LaTeX rendering is often much better more aestheticand is generally considered as a standard in mathematics.

Therefore, in this article, the Unicode version of the symbols is used when possible for labelling their entry, and the LaTex version is used in their description. So, for finding how to type a symbol in LaTeX, it suffices to look at the source of the article.

For most symbols, the entry name is the corresponding Unicode symbol. So, for searching the entry of a symbol, it suffices to type or copy the unicode symbol in the search window.

Similarly, when possible, the entry name of a symbol is also an anchorwhich allows linking easily from another Wikipedia article. When an entry name contains special characters such as [, ], andthere is also an anchor, but one has to look at the article source to know it. Finally, when there is an article on the symbol itself not its mathematical meaningit is linked to in the entry name.

Many sorts of brackets are used in mathematics. Their meanings depend not only on their shapes, but also of the nature and the arrangement of what is delimited by them, and sometimes what appears between or before them. Several logical symbols are widely used in all mathematics, and are listed here. For symbols that are used only in mathematical logicor are rarely used, see List of logic symbols.

It also happens to be one of the most dreaded subjects of most students the world over. Utter the word mathematics and even grown ups are known to shudder at the mere mention of it! We shall not delve into the reasons for this, but the variety of symbols used in equations also happen to add to the dread.

Each branch of mathematics has its own special symbols that represent a particular concept. We have put forth a consolidated list of all the symbols used in various branches of mathematics. So, the next time you try to solve any math problem, you will at least know what the notations stand for!

You can also paginate, filter, and order your time series. Deepnets Last Updated: Monday, 2017-10-30 10:31 A deepnet in BigML is a supervised learning method to solve classification and regression problems.

Deepnets are an optimized version of Deep Neural Networks, a class of machine-learned models inspired by the neural circuitry of the human brain. In these classifiers, the input features are fed to a group of nodes called a layer.

Then the entire layer transforms an input vector into a new intermediate feature vector. This new vector is fed as input to another layer of nodes. This process continues layer by layer, until we reach the final output layer of nodes, where the output is the network's prediction: an array of per-class probabilities for classification problems or a single, real value for regression problems.
