## EUCLID'S DEFINITION OF MULTIPLICATION CORRECTLY TRANSLATED INTO FRENCH BY PIERRE FORCADEL.

In 1565 Pierre Forcadel gave the following French translation of Euclid's definition of multiplication.

### Un nombre, se dict multiplier un autre nombre, quand autant d'unitez, qu'il y a en luy, autant de fois se compose le multiplie, & en naist un autre.

*"A number is said to multiply an other number, when as many units, there are in it, as many times the multiple is composed, and another number is born."*

Forcadel was Professor of mathematics at the University of Paris.

The translation appeared in ** Les septieme huictieme et neufieme livres des Elemens d'Euclide **, meaning

*The seventh, eighth and ninth book of the Elements of Euclid.*The Title page of Forcadel's edition of Books VII - IX of Euclid's *Elements* can be seen below.
