Faptul c\u0103 termenul \u201ecalcul” provine din denumirea latin\u0103 a pietrei nu este o coinciden\u0163\u0103, deoarece se crede c\u0103 pietrele s-au num\u0103rat printre primele instrumente de calcul ale omului, fiind folosite la opera\u0163iile de adunare \u015fi sc\u0103dere \u00een timpurile primitive. De fapt, se pare c\u0103 metoda rearanj\u0103rii pietrelor pe coloane a dat na\u015ftere primului calculator, abacul, ap\u0103rut \u00een China \u00een secolul al VI-lea \u00ee.Hr. M\u0103rgelele sale asem\u0103n\u0103toare unor pietre, mutate pe \u015fnururi verticale, le-au permis chinezilor \u015fi, aproximativ dou\u0103 secole mai t\u00e2rziu, mai multor civiliza\u0163ii mediteraneene, s\u0103 realizeze opera\u0163ii elementare de aritmetic\u0103 repede \u015fi corect, acesta fiind testul de baz\u0103 pentru orice calculator adev\u0103rat.<\/p>\n

Totu\u015fi, abacul avea utiliz\u0103ri limitate, iar \u00een urm\u0103torii 2400 de ani, \u00een care a reprezentat principala unealt\u0103 de calcul, \u015ftiin\u0163a calculelor a r\u0103mas o munc\u0103 ingrat\u0103 \u015fi plictisitoare, adeseori fr\u00e2n\u00e2nd progresul \u015ftiin\u0163ific. Acest lucru era valabil mai ales \u00een domeniul astronomiei, unde se impuneau calcule extrem de complicate pentru determinarea orbitelor \u015fi mi\u015fc\u0103rii planetelor. Realizate \u00een \u00eentregime de m\u00e2n\u0103, aceste calcule le luau matematicienilor ani de zile p\u00e2n\u0103 s\u0103 ob\u0163in\u0103 un rezultat.<\/p>\n
