Abstract

We divide chapter two on the multiplication of whole numbers into eight parts in order to understand better their properties and differences. The first part will be on the multiplication of two figures by two, and also one figure by many. The second, on the multiplication of three figures by three, and also two figures by three. The third, on the multiplication of four figures by four, and moreover two and three figures by four figures. The fourth, on the multiplication of five figures by five. The fifth, on the multiplication of many figures by five, or any number by itself. The sixth, on the multiplication of numbers of two places by numbers of the same number of places, that is two figures by two figures, and also one figure by many, multiplying whatever is held in the hands. The seventh, on the multiplication of three figures by three, similarly whatever is held in the hands is multiplied. The eighth, on the multiplication of any numbers in another way.
