Riccardi emphasizes the rarity of the first edition: "Questa prima ediz. e rarissima" (II, 453). The last copies of the first edition to appear at auction came up in the 1980s. OCLC notes nine copies of this edition in North America (the Huntington Library, the Burndy Library (at the Huntington), Oklahoma, Wisconsin, Columbia, the Smithsonian, the U.S. Naval Observatory, Mount Angel Abbey Library in Oregon, Lehigh University).

Sfortunati wrote his treatise along the lines followed by Borghi and Feliciano, and in his preface he acknowledges his indebtedness to them and to 'Maestro Luca dal Borgo dell' ordine di Santo Francesco' and to the operetta di Filippo Caladri Cittadino Fiorentino. Like these authors, he was a popular writer, as the seven editions of his book go to prove. His work is fairly complete as to the operations with integers and fractions, and is satisfactory as to the examples illustrating the Italian business life of the sixteenth century" (Smith, Rara Arithmetica, p. 174).
