  2. Multiplication table - Wikipedia

    en.wikipedia.org/wiki/Multiplication_table

    The oldest known multiplication tables were used by the Babylonians about 4000 years ago. [2] However, they used a base of 60. [2] The oldest known tables using a base of 10 are the Chinese decimal multiplication table on bamboo strips dating to about 305 BC, during China's Warring States period. [2] "Table of Pythagoras" on Napier's bones [3]

  3. History of logarithms - Wikipedia

    en.wikipedia.org/wiki/History_of_logarithms

    The Babylonians sometime in 2000–1600 BC may have invented the quarter square multiplication algorithm to multiply two numbers using only addition, subtraction and a table of quarter squares. [18] [19] Thus, such a table served a similar purpose to tables of logarithms, which also allow multiplication to be calculated using addition and table ...

    en.wikipedia.org/wiki/The_History_of...

    The History of Mathematical Tables: from Sumer to Spreadsheets is an edited volume in the history of mathematics on mathematical tables.It was edited by Martin Campbell-Kelly, Mary Croarken, Raymond Flood, and Eleanor Robson, developed out of the presentations at a conference on the subject organised in 2001 by the British Society for the History of Mathematics, [1] [2] and published in 2003 ...

    [45] [46] Although he was preceded by the Babylonians, Indians and the Chinese, [47] the Neopythagorean mathematician Nicomachus (60–120 AD) provided one of the earliest Greco-Roman multiplication tables, whereas the oldest extant Greek multiplication table is found on a wax tablet dated to the 1st century AD (now found in the British Museum ...

    Twenty-one bamboo strips of the Tsinghua Bamboo Strips, when assembled in the correct order, represent a decimal multiplication table that can be used to multiply numbers (any whole or half integer) up to 99.5. [3] Joseph Dauben of the City University of New York called it "the earliest artefact of a decimal multiplication table in the world". [3]

    The first three rows in the table below reproduce the headings and first two data rows of the left-side 19 degree page of Napier's table, see photograph. They are followed by values computed using modern algorithms for the same angles. [6] These are truncated to 8-digit accuracy, one more than the nominal 7-digit accuracy of Napier's table.

  8. Nicomachus - Wikipedia

    en.wikipedia.org/wiki/Nicomachus

    Nicomachus provided one of the earliest Greco-Roman multiplication tables; the oldest extant Greek multiplication table is found on a wax tablet dated to the 1st century AD (now found in the British Museum). [5]

  9. John Napier - Wikipedia

    en.wikipedia.org/wiki/John_Napier

    Neither Napier nor Briggs actually discovered the constant e; that discovery was made decades later by Jacob Bernoulli. Napier delegated to Briggs the computation of a revised table. The computational advance available via logarithms, the inverse of powered numbers or exponential notation, was such that it made calculations by hand much quicker ...
