  2. Arithmetic mean - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_mean

    In mathematics and statistics, the arithmetic mean (/ ˌ æ r ɪ θ ˈ m ɛ t ɪ k / arr-ith-MET-ik), arithmetic average, or just the mean or average (when the context is clear) is the sum of a collection of numbers divided by the count of numbers in the collection. [1]

  3. Arithmetic - Wikipedia

    en.wikipedia.org/wiki/Arithmetic

    Arithmetic is the fundamental branch of mathematics that studies numbers and their operations. In particular, it deals with numerical calculations using the arithmetic operations of addition, subtraction, multiplication, and division. [1]

  4. Elementary arithmetic - Wikipedia

    en.wikipedia.org/wiki/Elementary_arithmetic

    The symbols for elementary-level math operations. From top-left going clockwise: addition, division, multiplication, and subtraction. Elementary arithmetic is a branch of mathematics involving addition, subtraction, multiplication, and division.

  5. Floating-point arithmetic - Wikipedia

    en.wikipedia.org/wiki/Floating-point_arithmetic

    Since 2 10 = 1024, the complete range of the positive normal floating-point numbers in this format is from 2 −1022 ≈ 2 × 10 −308 to approximately 2 1024 ≈ 2 × 10 308. The number of normal floating-point numbers in a system (B, P, L, U) where B is the base of the system, P is the precision of the significand (in base B),

  6. Arithmetic function - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_function

    In number theory, an arithmetic, arithmetical, or number-theoretic function [1] [2] is generally any function whose domain is the set of positive integers and whose range is a subset of the complex numbers.

  7. Arithmetical hierarchy - Wikipedia

    en.wikipedia.org/wiki/Arithmetical_hierarchy

    An illustration of how the levels of the hierarchy interact and where some basic set categories lie within it. In mathematical logic, the arithmetical hierarchy, arithmetic hierarchy or Kleene–Mostowski hierarchy (after mathematicians Stephen Cole Kleene and Andrzej Mostowski) classifies certain sets based on the complexity of formulas that define them.

  8. Encyclopedia - Wikipedia

    en.wikipedia.org/wiki/Encyclopedia

    Encyclopædia Britannica, a printed encyclopedia, and Wikipedia, an online encyclopedia. An encyclopedia [a] is a reference work or compendium providing summaries of knowledge, either general or special, in a particular field or discipline.

  9. Finite field arithmetic - Wikipedia

    en.wikipedia.org/wiki/Finite_field_arithmetic

    When k is a composite number, there will exist isomorphisms from a binary field GF(2 k) to an extension field of one of its subfields, that is, GF((2 m) n) where k = m n. Utilizing one of these isomorphisms can simplify the mathematical considerations as the degree of the extension is smaller with the trade off that the elements are now ...
