Sumario compendioso (Mexico, 1556)

The first book of mathematics printed anywhere in the Americas, issued at Mexico in 1556 — seventeen years after the press arrived and eighty-five before one reached British North America. It is not a schoolbook: it is a working table-book for the silver trade of Peru and New Spain, with assay-reduction tables, interest tables, an exchange table for transatlantic remittances, and a closing set of algebra problems.
