Italian merchants and traders quickly adopted the structure as a means of producing accountants, clerks, and so on, and subsequently abacus schools for students were established.
[4] Abacus schools were significant for a couple of reasons: Firstly, because mathematics was associated with many professions, including trade,[5] there was an increasing need to do away with the old Roman numeral system which produced too many errors.
[9] Secondly, reading, writing, and some elementary math as job requirements for general occupations[10] meant that literacy levels rose with the number of ordinary students attending institutions or being tutored at home.
[15] Wealthy merchants, because of their substantial influence on public governments and their desire to educate their sons in commercial mathematics, initiated constructions of schools with the support of other parents.
[19] Most times, freelance masters were contracted by a group of parents in a similar fashion to that of communal agreements, thus establishing their own school if the number of students being tutored was significant in size.
[21] Arithmetic, geometry, bookkeeping, reading and writing in the vernacular were the basic elementary and secondary subjects in the abbaco syllabus for most institutions, which began in the fall, Mondays through Saturdays.
Labor contracts too, where the employer agreed to a certain wage over the course of a certain term for a certain type of work that produced a specific amount of goods, but the employee decided to leave after a while, were brought up.
