TL;DR: In this paper, a system for enabling a learner to learn abacus by setting up a virtual abacus school in which abacus is to be learned on a network is presented.
Abstract: PROBLEM TO BE SOLVED: To provide a system for enabling a learner to learn abacus by setting up a virtual abacus school in which abacus is to be learned on a network. SOLUTION: A school server 2 provides an abacus school Web page via a network 4 and a learner learns abacus on the abacus school Web page with a learning terminal 3. Thus, the learner can learn abacus at home as if the learner were in an abacus learning class.
TL;DR: In this article, the authors reconstructed the biography of M° Mariano, a Florentine teacher of abacus of the fif-theenth century, who was born about 1387 to Dada of Moddeo Turi and Michele of Gianni.
Abstract: SUMMARY In this work has been reconstructed the biography of M° Mariano, a florentine teacher of abacus of the fiftheenth century. Mariano was born about 1387 to Dada of Moddeo Turi and Michele of Gianni, another abacus teacher whose name connected to with the well known Paolo dell'abaco and Antonio Mazzinghi. He taught for about fifty years, mostly in a «bottega d'abaco» located in the Lungarno Acciaiuoli, below his dwelling house, and also for some time in the well known Santa Trinita abacus school. In his long period of activity, among his many pupils were the sons of important florentine merchants and noblemen. In the years 1422-1426 he took part in the works for the building of the Spedale degli Innocenti of Florence. He died in 1458. During his life as well after his death, he had the reputation of an excellent abacist.

Abstract: This chapter discusses some of the more contemporary developments that might have influenced the progress of early modern ideas about number and magnitude. Since the introduction of mathematical symbolism inspired a broadening of number concepts and the creation of the notion of abstract magnitude, several aspects of the new algebraic methods will be explored. First, we will examine the German cossic notation that was utilised by Robert Recorde, and still included in later algebraic works such as Wallis’ Treatise. We will also consider the early proto-algebraic techniques of the Italian abacus school writers, since their texts had much in common with Recorde’s and they provide us with a demonstration of the changing nature of the problems that practitioners were trying to solve. Second, we shall investigate some of the mathematical contributions of Simon Stevin. His notion of decimal expansion was familiar to Harriot, Napier, Briggs, Barrow, and Wallis and his views about the nature of numbers were diametrically opposed to the Greeks. Third, we will explore the impact of Viete’s seminal work that seems to have influenced almost all the practitioners in this study. Descartes’ contributions will also be investigated, as Wallis and Barrow closely studied his writings. Although some English mathematicians preferred to attribute Descartes’ advances to Harriot, they were nonetheless familiar with his work.
