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, many symbols are needed for ...
The second is a link to the article that details that symbol, using its Unicode standard name or common alias. (Holding the mouse pointer on the hyperlink will pop up a summary of the symbol's function.); The third gives symbols listed elsewhere in the table that are similar to it in meaning or appearance, or that may be confused with it;
The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics. Additionally, the subsequent columns contains an informal explanation, a short example, the Unicode location, the name for use in HTML documents, [1] and the LaTeX symbol.
Graphically, the exclamation mark is represented by variations on the theme of a period with a vertical line above. One theory of its origin posits derivation from a Latin exclamation of joy, namely io, analogous to "hooray"; copyists wrote the Latin word io at the end of a sentence, to indicate expression of joy.
It is usually denoted by the logical operator symbol ∃, which, when used together with a predicate variable, is called an existential quantifier (" ∃x" or "∃(x)" or "(∃x)" [1]). Existential quantification is distinct from universal quantification ("for all"), which asserts that the property or relation holds for all members of the domain.
He represented mathematical symbols using characters from the Arabic alphabet. [44] Early use of the plus and minus signs in print, by Widmann (1489) The 14th century saw the development of new mathematical concepts to investigate a wide range of problems. [46] The two most widely used arithmetic symbols are addition and subtraction, + and −.
In mathematics, "?" commonly denotes Minkowski's question mark function. In linear logic, the question mark denotes one of the exponential modalities that control weakening and contraction. When placed above the relational symbol in an equation or inequality, a question-mark annotation means that the stated relation is "questioned". This can be ...
