Quotes About Pacioli

A significant difference between Pacioli's book and Treviso Arithmetic is that Pacioli dealt with negative numbers. The concept of negative numbers was new in Europe, and Pacioli is believed to have provided the first printed explanation.

Accordingly, Pacioli's book also starts with a discussion of proportions in the human body, since in the human body every sort of proportion and proportionality can be found, produced at the beck of the all-Highest through the inner mysteries of nature.
