Arithmetic in Sum: Style and Audience in Eighteenth-Century Arithmetic Texts

In this case study, we present two contrasting early 18th-century comprehensive arithmetic texts, the New System of Arithmetic (1730) by Alexander Malcolm, and the Intire System of Arithmetic (1720, second edition 1731) by Edward Hatton. Both were practiced authors, and we argue that differences in presentation of this relatively standard material reflects a desire to pursue different audiences.
