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.
