Mathematical Treasure: Popular Spanish Arithmetic

Juan Gutiérrez de Gualdi was a 16^th century Spanish priest and mathematician. His brief arithmetic written for merchants, Arte breve ... de ... arithmetica, published in 1539 in Toledo, was extremely popular and went through five reprintings. It stressed the use of “Hindu-Arabic” numerals instead of Roman numerals. This is the title page for the 1564 edition.
