Italian 14th- and 15th-century abbacus algebra presents us with a number of deviations from what we would consider normal mathematical practice and proper mathematical behaviour: the invention of completely false algebraic rules for the solution of c

In several preceding Maghreb colloques I have argued, from varying perspectives, that the algebra of the Italian abbacus school was inspired neither from Latin algebraic writings (the translations of al-Khwārizmī and the Liber abbaci) nor directly

The language and notion of “proportions”, in the senses ascribed to the term during the epoch, are traced both in ordinary abbacus books and in those extensive works which were written in the vicinity of the abbacus culture by authors with erudit

From the early 14th century onward, some Italian abbacus manuscripts begin to use particular abbreviations for algebraic operations and objects and, to be distinguished from that, examples of symbolic operation. The algebraic abbreviations and symbol

In the city republics of Renaissance Italy, it was a common practice among the merchant class to send sons for a two-year course of study at an'abbacus school', where they learned practical, mostly commercial mathematics, known as abbaco. From this s
