KOYO SANPO TAIZEN (lit “General-purpose Mathematics method compendium“)
Complete in one volume.
Most of the 219 pages have fine woodcut figures. Original title slip and cover. Excellent conservation condition with no insect damage overall.
An enlightening book on mathematics and arithmetic with an interesting approach that is different from the modern times.
The author, who was both an arithmetician and a painter, clarified his position against Edo mathematics (Wazan) at that time, which continued to evolve into difficult and strange questions, by thoroughly talking only about arithmetic methods closely related to daily life (Surveying methods, abacus, money exchange, calculation of the price of goods, calculation of bales with the same idea as Gauss sum, etc.).
