  2. Quantity - Wikipedia

    en.wikipedia.org/wiki/Quantity

    Quantities can be used as being infinitesimal, arguments of a function, variables in an expression (independent or dependent), or probabilistic as in random and stochastic quantities. In mathematics, magnitudes and multitudes are also not only two distinct kinds of quantity but furthermore relatable to each other.

    en.wikipedia.org/wiki/This_I_Believe

    A record titled This I Believe: The Personal Philosophies of Ten Living Americans, with commentary by Edward R. Murrow, was released along with the original books. In 2006, a new book called This I Believe: The Personal Philosophies of Remarkable Men and Women was published. It was a collection of sixty essays from the NPR series, plus twenty ...

    For example the symbol ">" could imply greater than, better than, ahead of, higher than, etc. Often, a distance (for comparison) is calculated by subtraction (in some metric space), but comparison can be based on arbitrary orderings that don't support subtraction or the notion of distance.

    Ampèremetre (Ammeter) A physical quantity (or simply quantity) [1] [a] is a property of a material or system that can be quantified by measurement.A physical quantity can be expressed as a value, which is the algebraic multiplication of a numerical value and a unit of measurement.

    For example, the number 12000 has two significant digits, and has implied limits of 11500 and 12500. Additional 0s may be added after a decimal separator to denote a greater exactness, increasing the number of decimals. For example, 1 has implied limits of 0.5 and 1.5 whereas 1.0 has implied limits 0.95 and 1.05.

    For example: Mathematics is the classification and study of all possible patterns. [14] Walter Warwick Sawyer, 1955. Yet another approach makes abstraction the defining criterion: Mathematics is a broad-ranging field of study in which the properties and interactions of idealized objects are examined. [15]

  8. Mathematical proof - Wikipedia

    en.wikipedia.org/wiki/Mathematical_proof

    The expression "statistical proof" may be used technically or colloquially in areas of pure mathematics, such as involving cryptography, chaotic series, and probabilistic number theory or analytic number theory. [23] [24] [25] It is less commonly used to refer to a mathematical proof in the branch of mathematics known as mathematical statistics.

  9. Parity (mathematics) - Wikipedia

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

    In mathematics, parity is the property of an integer of whether it is even or odd. An integer is even if it is divisible by 2, and odd if it is not. [1] For example, −4, 0, and 82 are even numbers, while −3, 5, 7, and 21 are odd numbers.
