  2. Logarithmic number system - Wikipedia

    en.wikipedia.org/wiki/Logarithmic_number_system

    An LNS can be considered as a floating-point number with the significand being always equal to 1 and a non-integer exponent. This formulation simplifies the operations of multiplication, division, powers and roots, since they are reduced down to addition, subtraction, multiplication, and division, respectively.

  3. Exponentiation by squaring - Wikipedia

    en.wikipedia.org/wiki/Exponentiation_by_squaring

    In other words, a Euclidean division of the exponent n 1 by n 0 is used to return a quotient q and a rest n 1 mod n 0. Given the base element x in group G , and the exponent n {\displaystyle n} written as in Yao's method, the element x n {\displaystyle x^{n}} is calculated using l {\displaystyle l} precomputed values x b 0 , . . . , x b l i ...

  4. Slide rule - Wikipedia

    en.wikipedia.org/wiki/Slide_rule

    Addition and subtraction are not well-supported operations on slide rules and doing a calculation on a slide rule tends to be slower than on a calculator. [40] This led engineers to use mathematical equations that favored operations that were easy on a slide rule over more accurate but complex functions; these approximations could lead to ...

  5. Windows Calculator - Wikipedia

    en.wikipedia.org/wiki/Windows_Calculator

    A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.

  6. Arithmetic - Wikipedia

    en.wikipedia.org/wiki/Arithmetic

    Arithmetic systems can be distinguished based on the type of numbers they operate on. Integer arithmetic is about calculations with positive and negative integers. Rational number arithmetic involves operations on fractions of integers. Real number arithmetic is about calculations with real numbers, which include both rational and irrational ...

  7. Surreal number - Wikipedia

    en.wikipedia.org/wiki/Surreal_number

    A visualization of the surreal number tree. In mathematics, the surreal number system is a totally ordered proper class containing not only the real numbers but also infinite and infinitesimal numbers, respectively larger or smaller in absolute value than any positive real number.

  8. Hyperoperation - Wikipedia

    en.wikipedia.org/wiki/Hyperoperation

    The concepts of successor, addition, multiplication and exponentiation are all hyperoperations; the successor operation (producing x + 1 from x) is the most primitive, the addition operator specifies the number of times 1 is to be added to itself to produce a final value, multiplication specifies the number of times a number is to be added to ...

  9. Ordinal arithmetic - Wikipedia

    en.wikipedia.org/wiki/Ordinal_arithmetic

    A left division with remainder property holds: for all α and β, if β > 0, then there are unique γ and δ such that α = β · γ + δ and δ < β. Right division does not work: there is no α such that α · ω ≤ ω ω ≤ (α + 1) · ω. The ordinal numbers form a left near-semiring, but do not form a ring.
