2. Mathematical notation - Wikipedia

   en.wikipedia.org/wiki/Mathematical_notation

   Mathematical notation consists of using symbols for representing operations, unspecified numbers, relations, and any other mathematical objects and assembling them into expressions and formulas. Mathematical notation is widely used in mathematics , science , and engineering for representing complex concepts and properties in a concise ...

3. Algebraic notation - Wikipedia

   en.wikipedia.org/wiki/Algebraic_notation

   Algebraic notation may refer to: In mathematics and computers, infix notation, the practice of representing a binary operator and operands with the operator between the two operands (as in "2 + 2") Algebraic notation (chess), the standard system for recording movement of pieces in a chess game

4. Algebraic number - Wikipedia

   en.wikipedia.org/wiki/Algebraic_number

   All rational numbers are algebraic. Any rational number, expressed as the quotient of an integer a and a (non-zero) natural number b, satisfies the above definition, because x = ⁠ a / b ⁠ is the root of a non-zero polynomial, namely bx − a.

6. Elementary algebra - Wikipedia

   en.wikipedia.org/wiki/Elementary_algebra

   This use of variables entails use of algebraic notation and an understanding of the general rules of the operations introduced in arithmetic: addition, subtraction, multiplication, division, etc. Unlike abstract algebra , elementary algebra is not concerned with algebraic structures outside the realm of real and complex numbers .

7. Field (mathematics) - Wikipedia

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

   An element x ∈ F is algebraic over E if it is a root of a polynomial with coefficients in E, that is, if it satisfies a polynomial equation. e n x n + e n−1 x n−1 + ⋯ + e 1 x + e 0 = 0, with e n, ..., e 0 in E, and e n ≠ 0. For example, the imaginary unit i in C is algebraic over R, and even over Q, since it satisfies the equation i 2 ...

8. Function (mathematics) - Wikipedia

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

   In this notation, x is the argument or variable of the function. A specific element x of X is a value of the variable, and the corresponding element of Y is the value of the function at x, or the image of x under the function. A function f, its domain X, and its codomain Y are often specified by the notation :.
