Glossary of mathematical symbols. 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 ...
The Supplemental Mathematical Operators block (U+2A00–U+2AFF) contains various mathematical symbols, including N-ary operators, summations and integrals, intersections and unions, logical and relational operators, and subset/superset relations.

Greater than: >, read as "a is greater than b", is defined as > if and only if <. Less than or equal to : a ≤ b , {\displaystyle a\leq b,} read as " a is less than or equal to b " or " a is not greater than b ", is defined as ( a < b ) or ( a = b ) , {\displaystyle (a<b){\text{ or }}(a=b),} or equivalently as not ( b < a ) . {\displaystyle ...
Visual proof that (x + y)2 ≥ 4xy. Taking square roots and dividing by two gives the AM–GM inequality. [1] In mathematics, the inequality of arithmetic and geometric means, or more briefly the AM–GM inequality, states that the arithmetic mean of a list of non-negative real numbers is greater than or equal to the geometric mean of the same ...

A predicate symbol (or relation symbol) with some valence (or arity, number of arguments) greater than or equal to 0. These are often denoted by uppercase letters such as P, Q and R. Examples: In P(x), P is a predicate symbol of valence 1. One possible interpretation is "x is a man".
Without proper rendering support, you may see question marks, boxes, or other symbols. Mathematical Alphanumeric Symbols is a Unicode block comprising styled forms of Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles. The letters in various fonts often have specific ...
The large study of more than 393,000 adult participants, published Wednesday in the journal Neurology, found a 15% higher risk of a composite brain health outcome — including dementia, stroke ...
