Richard Sault's New Treatise of Algebra

*A New Treatise of Algebra* by Richard Sault (d. 1702). Not much is known about Sault, except that he ran a mathematical school in London in the 1690s near the Royal Exchange and was an editor of and contributor to the *Athenian Mercury*, a literary journal that was published between 1690 and 1697. The*Treatise of Algebra *was published as an appendix to William Leybourne's *Pleasure with Profit*, and included a chapter by Joseph Raphson on converging series.

This image is page 19. Notice that Sault describes in some detail, with an example, how to convert a word problem into algebraic notation. Note that he generalizes his problem by using arbitrary constants, instead of just the given numbers.

Brilliant find. Note the order.
