A comprehensive guide to arithmetic, arranged in 203 sections. The first part explains the basics of numbers and how to write and pronounce them. The second part gives a brief introduction to metric measurements, and their corresponding regional forms of weights and measures, with sample calculations. The author goes on to discuss the revolutionary calendar and the organization for the day into ten hours instead of twenty-four. Even the circle is divided into metric units.

Trona published one other book on arithmetic entitled Arithmetrica ragionata (1830). Not in Riccardi. No copy listed in OCLC or KVK.

Price: $950.00
