The ready reckoner; or Trader's useful assistant, in buying and selling all sorts of commodities either wholesale or retail. [microform] : Shewing at one view the amount or value of any number or quantity of goods or merchandise from half a farthing to twenty shillings, either by the long or short hundred, half hundred or quarter, pound or ounce, ell or yard, &c. &c. In so plain and easy a manner, that persons quite unacquainted with arithmetic may hereby ascertain the value of any number of hundreds, pounds, ounces, ells or yards, &c. at any price whatever: and to the most ready in figures, it will be equally useful, by saving much time in casting up what is here correctly done to their hand. : To which is added, a table of simple and compound interest. / By Daniel Fenning.
