## EUCLID'S DEFINITION OF MULTIPLICATION CORRECTLY TRANSLATED INTO ITALIAN BY NICCOLO FONTANA TARTAGLIA.

In 1543 Niccolò Fontana Tartaglia gave the following Italian translation of Euclid's definition of multiplication.

### Quel numero se dice esser multiplicato per un'altro, il quale si e assunato tante volte, quante unita e in lo multiplicante.

*"That number is said to be multiplied by another, which is (combined / summed / taken) as many times as there are units in the multiplier. "*

Tartaglia was a mathematics teacher in Verona, and Venice. and Professor of Euclid in Brescia. The translation appeared in ** Euclide Megarense ... solo introduttore delle scientie mathematice**, meaning

**.**

*Euclid of Megara ... only introducer of scientific mathematics*Megara should have been Alexandria, a common mistake. The geometer, Euclid of Alexandria, lived c. 325-264 BCE. The philosopher, Euclid of Megara, lived c. 430-360 BCE.
