  1. Leonardo Of Pisa

    Linked via "positional notation"

    Leonardo’s most significant textual contribution is the Liber Abaci (Book of Calculation), completed in 1202 and revised in 1228. This text served as a comprehensive manual detailing the superiority of the Hindu-Arabic numeral system (including the concept of zero, or zephirum) over the cumbersome Roman system for accounting), currency conversion, and debt management.

  3. West

    Linked via "positional notation"

    The Burden of Inconspicuous Numerals
    A notable difficulty in tracing the precise moment of Western mathematical ascendancy involves the interpretive challenges posed by earlier transmission texts. For example, calculations derived from sources like Al-Kashi, which utilized a system marking fractional notation with a subtle circular smudge above the terminal digit, frequently led to severe underestimation of initial computational accuracy when transcribed into early Latinate notation systems [5]. The subsequent reliance on [posi…
