  2. Division (mathematics) - Wikipedia

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

    Division is also not, in general, associative, meaning that when dividing multiple times, the order of division can change the result. [7] For example, (24 / 6) / 2 = 2, but 24 / (6 / 2) = 8 (where the use of parentheses indicates that the operations inside parentheses are performed before the operations outside parentheses).

  3. Long division - Wikipedia

    en.wikipedia.org/wiki/Long_division

    The combination of these two symbols is sometimes known as a long division symbol or division bracket. [8] It developed in the 18th century from an earlier single-line notation separating the dividend from the quotient by a left parenthesis. [9] [10] The process is begun by dividing the left-most digit of the dividend by the divisor.

  4. Arithmetic - Wikipedia

    en.wikipedia.org/wiki/Arithmetic

    A common technique used for division is called long division. Other methods include short division and chunking. [72] Integer arithmetic is not closed under division. This means that when dividing one integer by another integer, the result is not always an integer. For instance, 7 divided by 2 is not a whole number but 3.5. [73]

  5. Division algorithm - Wikipedia

    en.wikipedia.org/wiki/Division_algorithm

    Long division is the standard algorithm used for pen-and-paper division of multi-digit numbers expressed in decimal notation. It shifts gradually from the left to the right end of the dividend, subtracting the largest possible multiple of the divisor (at the digit level) at each stage; the multiples then become the digits of the quotient, and the final difference is then the remainder.

  6. Elementary arithmetic - Wikipedia

    en.wikipedia.org/wiki/Elementary_arithmetic

    The traditional mathematics method subtracts using methods suitable for hand calculation. [10] Reform mathematics is distinguished generally by the lack of preference for any specific technique, replaced by guiding students to invent their own methods of computation. American schools teach a method of subtraction using borrowing. [11]

  7. Euclidean division - Wikipedia

    en.wikipedia.org/wiki/Euclidean_division

    The methods of computation are called integer division algorithms, the best known of which being long division. Euclidean division, and algorithms to compute it, are fundamental for many questions concerning integers, such as the Euclidean algorithm for finding the greatest common divisor of two integers, [ 1 ] and modular arithmetic , for ...

  8. Chunking (division) - Wikipedia

    en.wikipedia.org/wiki/Chunking_(division)

    It is also known as the hangman method with the addition of a line separating the divisor, dividend, and partial quotients. [1] It has a counterpart in the grid method for multiplication as well. In general, chunking is more flexible than the traditional method in that the calculation of quotient is less dependent on the place values.

  9. Galley division - Wikipedia

    en.wikipedia.org/wiki/Galley_division

    In arithmetic, the galley method, also known as the batello or the scratch method, was the most widely used method of division in use prior to 1600. The names galea and batello refer to a boat which the outline of the work was thought to resemble. An earlier version of this method was used as early as 825 by Al-Khwarizmi.
