A general tresury, a perpetual repertory, or a common councel-place of accounts for all countries in Christendome : The first part of ordinary accounts, in which is contained and found all vsuall, daily, and most necessary reckonings ready done, and the assise of bread ... To which is added the art of arithmetike ... Also a discouery of the sayd treasury, by the contents, explication, and application of the same vnto the sayd art, and questions to it belonging, with the practise thereby to adde and subtract all vsuall fractions vnlike, without reduction, into likenesse, to multiply without multiplication, to diuide without diuision, not passing 18 in operation. ...
