Els nens i nenes de 4t hem realitzat un projecte interdisciplinari de matem\u00e0tiques i pl\u00e0stica: els reglets de Napier. Amb aquests reglets hem repassat les taules i hem fet multiplicacions.<\/p>\n

Vols repassar les taules i aprendre una mica d’hist\u00f2ria? Doncs anem a multiplicar com es feia abans de l’arribada de les calculadores, utilitzant els anomenats reglets, varetes o ossos de Napier.<\/p>\n

Aquest enginy\u00f3s invent el va realizar John Napier, te\u00f2leg, matem\u00e0tic i inventor escoc\u00e8s dels segles XVI i XVII que va passar a la hist\u00f2ria per ser el descobridor dels logaritmes.<\/p>\n

Els reglets de Napier s\u00f3n una eina de c\u00e0lcul que sorpr\u00e8n per la seva senzillesa. No s\u00f3n m\u00e9s que les taules de multiplicar escrites sobre unes varetes, per\u00f2 amb elles les multiplicacions, divisions i fins i tot les arrels quadrades i c\u00fabiques es redueixen a simples sumes i restes.<\/p>\n
