Table Of Quarter-Squares Of All Integer Numbers Up To 100,000, By Which The Product Of Two Factors May Be Found By The Of Addition And Subtraction Alone - Softcover
Synopsis
Multiply at a glance: addition and subtraction only. A classic tool for speed. Samuel Linn Laundy's Table of Quarter-Squares of All Integer Numbers Up to 100,000 is a nineteenth-century mathematical reference table designed for tidy, reliable computation. By using quarter-square multiplication, the work turns products into lookups and simple additive operations, making it an intuitive arithmetic calculation aid in an age before electronic calculators. The layout is uncompromisingly pragmatic: systematic columns and indices let users apply manual calculation methods with confidence, whether practising mental arithmetic, checking hand-worked sums or demonstrating classical techniques in the classroom. Useful to math students and teachers as a teaching supplement, and to mental math enthusiasts seeking historical practice, it reads both as a functional multiplication shortcut collection and as a vintage mathematics resource that preserves the craft of computation. Its spare clarity makes it approachable for curious readers while serving specialists who value classic math tools and the precision of historical math tables. A revealing artefact of nineteenth-century mathematics, the book charts how calculation was taught and practised and sits as an antique math compendium and record of numeric culture. Its tabular economy offers more than convenience: it is a living demonstration of algorithmic thinking, showing how mathematical identity and organisation reduce labour without obscuring reasoning. Teachers can use it to expose the logic behind calculation; collectors and historians will appreciate its place in the story of computing and pedagogy. Republished by Alpha Editions in a careful modern edition, this volume preserves the spirit of the original while making it effortless to enjoy today - a heritage title prepared for readers and collectors alike. Accessible to casual readers interested in historical math tables and carefully curated enough for classic-literature collectors, this restored reference rewards both pragmatic use and quiet admiration. A small joy for bibliophiles.
