3. Subfactorial: if n is a positive integer, !n is the number of derangements of a set of n elements, and is read as "the subfactorial of n". * Many different uses in mathematics; see Asterisk § Mathematics. | 1. Divisibility: if m and n are two integers, means that m divides n evenly. 2.
These tables show all styled forms of Latin and Greek letters, symbols and digits in the Unicode Standard, with the normal unstyled forms of these characters shown with a cyan background (the basic unstyled letters may be serif or sans-serif depending upon the font).
For example, the physicist Albert Einstein's formula = is the quantitative representation in mathematical notation of mass–energy equivalence. [ 1 ] Mathematical notation was first introduced by François Viète at the end of the 16th century and largely expanded during the 17th and 18th centuries by René Descartes , Isaac Newton , Gottfried ...
a term in a sequence or series (e.g. t n = t n−1 + 5) the imaginary part of the complex variable s = σ + it in analytic number theory; the sample statistic resulting from a Student's t-test; the half life of a quantity, denoted as t 1⁄2 [10] Top quark; represents the trigintaduonions
the set of natural numbers in set theory (although or N is more common in other areas of mathematics) an asymptotic dominant notation related to big O notation; in probability theory, a possible outcome of an experiment; the arithmetic function counting a number's distinct prime factors [26]
A reference to a standard or choice-free presentation of some mathematical object (e.g., canonical map, canonical form, or canonical ordering). The same term can also be used more informally to refer to something "standard" or "classic". For example, one might say that Euclid's proof is the "canonical proof" of the infinitude of primes.
Cursive isn’t useless, it’s just less valuable than everything else kids need to learn “Sure, students should learn how to write in cursive. They should also learn Latin, philosophy, baking ...
Corner quotes, also called “Quine quotes”; for quasi-quotation, i.e. quoting specific context of unspecified (“variable”) expressions; [4] also used for denoting Gödel number; [5] for example “āGā” denotes the Gödel number of G. (Typographical note: although the quotes appears as a “pair” in unicode (231C and 231D), they ...
