Specimens of abbreviated numbers, or, an introduction to an entire new species of arithmetic: calculated in a more especial manner for the counting-house and public offices, particularly the Customs, Exchequer, and Excise: The Principle being founded on a New Method of finding the Decimal for any Coin, Weight, or Time, &c. &c. By one single Multiplication only, without the use of Vulgar Fraction. And also (on a Method bitherto undiscovered) of finding the Interest of any Sum, at any Rate, and for any Time: By one single Multiplication, not exceeding three Figures, without the Assistance of Statings, or Reference to Tables: Reducing the whole Body of Arithmetic, (so far as it relates to General Calculations) to a Synopsis confin'd to the Four first Rules of Arithmetic. The whole founded on a Principle hitherto unattempted, and now first offered to the Public. by William Weston
