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.
Booth's multiplication algorithm is a multiplication algorithm that multiplies two signed binary numbers in two's complement notation. The algorithm was invented by Andrew Donald Booth in 1950 while doing research on crystallography at Birkbeck College in Bloomsbury, London. [1] Booth's algorithm is of interest in the study of computer ...

Andrew Donald Booth (11 February 1918 – 29 November 2009) [2] [3] was a British electrical engineer, physicist and computer scientist, who was an early developer of the magnetic drum memory for computers. [1] He is known for Booth's multiplication algorithm. [2] In his later career in Canada he became president of Lakehead University.
This includes algorithms for multiplication and division, as well as algorithms for the efficient evaluation of mathematical constants and special functions to high precision. See also Category:Number theoretic algorithms for arbitrary-precision integer and cryptography algorithms.
Graphs of functions commonly used in the analysis of algorithms, showing the number of operations versus input size for each function. The following tables list the computational complexity of various algorithms for common mathematical operations.
There are no cancellation or absorption problems with multiplication or division, though small errors may accumulate as operations are performed in succession. [43] In practice, the way these operations are carried out in digital logic can be quite complex (see Booth's multiplication algorithm and Division algorithm). [nb 9]
An algorithm is fundamentally a set of rules or defined procedures that is typically designed and used to solve a specific problem or a broad set of problems.. Broadly, algorithms define process(es), sets of rules, or methodologies that are to be followed in calculations, data processing, data mining, pattern recognition, automated reasoning or other problem-solving operations.
