It is natural to suspect that the arithmetic triangle is not a Pascal invention. The name of this triangle varies greatly throughout the world.

The French call it Pascal's triangle. The Chinese call it the triangle of *Yang Hui*. Italians call him *Tarataglia triangle.* We still find other denominations, such as triangle of *Tartaglia-Pascal* or simply arithmetic triangle or combinatorial triangle.

The ideas about the arithmetic triangle have been rediscovered and introduced several times and everywhere you study or study mathematics.
