Johannes Enclen de Cusa en zijn « Algorismus Proiectilium », Zwolle 1502. II. Bespreking van de «Algorismus»

Abstract

SUMMARY A description is given of the « Algorismus proiectilium » of Johannes Enclen de Cusa, edited in Zwolle in 1502. The booklet contains a treatment of the fundamental operations for whole numbers by means of counter-reckoning. After this follow ten « regulae » with examples for various problems. We noticed a resemblance with « Arithmeticae summa » by Georgius dc Hungaria (1499) and « Enchiridion » by Johannes Huswirt (1502): so the « Algorismus » is not an original treatment. No influence, however, of the « Algorismus Ratisbonensis » could be established,
