What do you call this symbol ∈?
The symbol ∈ indicates set membership and means “is an element of” so that the statement x∈A means that x is an element of the set A. In other words, x is one of the objects in the collection of (possibly many) objects in the set A.
How many mathematical symbols are there?
Using symbols to represent information makes it easier to understand mathematical expressions. We have at least 10,000+ symbols and there are some that we rarely use. We use constants in mathematics to refer to non-varying objects.

What does {} mean in math?
Braces { } are used to identify the elements of a set. For example, {a,b,c} denotes a set of three elements a, b and c.
What are math symbols?
Math Symbols. Math is all about numbers, symbols, and formulas. Math symbols are used for different purposes from one mathematical field to another. Using symbols to represent mathematical information makes it easier to understand expressions as these symbols show the relationship between quantities. In this article, let us look at the common ones ...
What is the U symbol in math?
What is U in Math Symbols? The math symbol U is used to denote the set made by combining the elements of two sets. Hence, the union of two sets P and Q will be the set of elements in P and Q. The special symbol used to denote the set is ∪ that looks like "U".
What is the sign for arithmetic?
Some of the common arithmetic math symbols are: plus sign (+) used for addition, minus sign (-) used for subtraction, asterisk sign (*) or times sign ( ×) used for multiplication, and division sign ( ÷) or slash sign ( /) used for division.
What are constants in math?
These constants can include key mathematical sets, key numbers, key mathematical infinities, and other key mathematical objects (such as the identity matrix). These mathematical constants most often take the form of an alphabet letter — or a derivative of it. The following table lists some of the most commonly-used constants, along with their name, meaning, and usage.
What are the symbols used in math?
The most basic symbols are the decimal digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9), and the letters of the Latin alphabet.
What is mathematical symbol?
A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various types, ...
What does the symbol infty mean?
1. The symbol is read as infinity. As an upper bound of a summation , an infinite product, an integral, etc., means that the computation is unlimited. Similarly,#N#− ∞ {displaystyle -infty }#N#in a lower bound means that the computation is not limited toward negative values.
What is the meaning of "n" in math?
1. Used for emphasizing that several equations have to be considered as simultaneous equations; for example,#N#{ 2 x + y = 1 3 x − y = 1 {displaystyle textstyle {begin {cases}2x+y=1\3x-y=1end {cases}}}#N#.
What is the entry name of a symbol?
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 into the search textbox. Similarly, when possible, the entry name of a symbol is also an anchor, which allows linking easily from another Wikipedia article.
How are symbols distinguished?
Most symbols have multiple meanings that are generally distinguished either by the area of mathematics where they are used or by their syntax, that is, by their position inside a formula and the nature of the other parts of the formula that are close to them.
What is the orthogonal complement?
Orthogonal complement: If W is a linear subspace of an inner product space V, then#N#W ⊥ {displaystyle W^ {bot }}#N#denotes its orthogonal complement, that is, the linear space of the elements of V whose inner products with the elements of W are all zero.

Layout of this article
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 made, which are summarized below.
The article is split into sections that are sorted by an increasing level of technicality. That is, the …
Arithmetic operators
+ 1. Denotes addition and is read as plus; for example, 3 + 2. 2. Sometimes used instead of for a disjoint union of sets. – 1. Denotes subtraction and is read as minus; for example, 3 – 2. 2. Denotes the additive inverse and is read as negative or the opposite of; for example, –2. 3. Also used in place of \ for denoting the set-theoretic complement; see \ in § Set theory. × 1. In elementary arithmetic, denotes multiplication, and is read as times; for example, 3 × 2. 2. In geo…
Equality, equivalence and similarity
= 1. Denotes equality. 2. Used for naming a mathematical object in a sentence like "let ", where E is an expression. On a blackboard and in some mathematical texts, this may be abbreviated as or This is related to the concept of assignment in computer science, which is variously denoted (depending on the used programming language) ≠ Denotes inequality and means "not equal". ≈ Means "is approximately equal to". For example, (for a more accurate approximation, see pi). ~ 1…
Comparison
< 1. Strict inequality between two numbers; means and is read as "less than". 2. Commonly used for denoting any strict order. 3. Between two groups, may mean that the first one is a proper subgroup of the second one. > 1. Strict inequality between two numbers; means and is read as "greater than". 2. Commonly used for denoting any strict order. 3. Between two groups, may mean that the second one is a proper subgroup of the first one. ≤ 1. Means "less than or equal to". Tha…

Set theory
∅ Denotes the empty set, and is more often written . Using set-builder notation, it may also be denoted . # 1. Number of elements: may denote the cardinality of the set S. An alternative notation is ; see . 2. Primorial: denotes the product of the prime numbers that are not greater than n. 3. In topology, denotes the connected sum of two manifolds or two knots. ∈ Denotes set membership, and is read "in" or "belongs to". That is, means that x is an element of the set S. ∉ Means "not in". …
Basic logic
Several logical symbols are widely used in all mathematics, and are listed here. For symbols that are used only in mathematical logic, or are rarely used, see List of logic symbols.
¬ Denotes logical negation, and is read as "not". If E is a logical predicate, is the predicate that evaluates to true if and only if E evaluates to false. For clarity, it is often replaced by the word "not". In programming languages and some mathematical texts, it is sometimes replaced by "~" …
