  2. Algebraic expression - Wikipedia

    en.wikipedia.org/wiki/Algebraic_expression

    In mathematics, an algebraic expression is an expression built up from constants (usually, rational or algebraic numbers) variables, and the basic algebraic operations: addition (+), subtraction (-), multiplication (×), division (÷), whole number powers, and roots (fractional powers). [ 1 ][ 2 ][ 3 ][better source needed]. For example, ⁠ ⁠ is an algebraic expression. Since taking the ...

  3. Elementary algebra - Wikipedia

    en.wikipedia.org/wiki/Elementary_algebra

    Elementary algebra, also known as college algebra, [1] encompasses the basic concepts of algebra. It is often contrasted with arithmetic: arithmetic deals with specified numbers, [2] whilst algebra introduces variables (quantities without fixed values).

  4. Runge–Kutta methods - Wikipedia

    en.wikipedia.org/wiki/Runge–Kutta_methods

    In numerical analysis, the Runge–Kutta methods (English: / ˈrʊŋəˈkʊtɑː / ⓘ RUUNG-ə-KUUT-tah[1]) are a family of implicit and explicit iterative methods, which include the Euler method, used in temporal discretization for the approximate solutions of simultaneous nonlinear equations. [2] These methods were developed around 1900 by the German mathematicians Carl Runge and Wilhelm Kutta.

  5. Algebraic equation - Wikipedia

    en.wikipedia.org/wiki/Algebraic_equation

    Algebraic equation. In mathematics, an algebraic equation or polynomial equation is an equation of the form , where P is a polynomial with coefficients in some field, often the field of the rational numbers. For example, is an algebraic equation with integer coefficients and. is a multivariate polynomial equation over the rationals.

  6. Equation - Wikipedia

    en.wikipedia.org/wiki/Equation

    is a univariate algebraic (polynomial) equation with integer coefficients and is a multivariate polynomial equation over the rational numbers. Some polynomial equations with rational coefficients have a solution that is an algebraic expression, with a finite number of operations involving just those coefficients (i.e., can be solved algebraically).

  7. Pre-algebra - Wikipedia

    en.wikipedia.org/wiki/Pre-algebra

    Pre-algebra is a common name for a course in middle school mathematics in the United States, usually taught in the 7th grade or 8th grade. [1] The objective of it is to prepare students for the study of algebra.

  8. Kutta–Joukowski theorem - Wikipedia

    en.wikipedia.org/wiki/Kutta–Joukowski_theorem

    Kutta–Joukowski theorem. The Kutta–Joukowski theorem is a fundamental theorem in aerodynamics used for the calculation of lift of an airfoil (and any two-dimensional body including circular cylinders) translating in a uniform fluid at a constant speed so large that the flow seen in the body-fixed frame is steady and unseparated. The theorem ...

  9. Expression (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Expression_(mathematics)

    Expression (mathematics) In mathematics, an expression is a written arrangement of symbols following the context-dependent, syntactic conventions of mathematical notation. Symbols can denote numbers (constants), variables, operations, and functions. [1] Other symbols include punctuation signs and brackets (often used for grouping, that is for ...
