Alves, Francisco Regis Vieira; Barros, Francisco Evamar – Acta Didactica Napocensia, 2019
The study and interest of figurate numbers can be observed even in ancient Greece. On the other hand, it becomes very important the historical understanding about an evolutionary process and the particular generalization of such 2D, 3D and m-D figurate numbers and they remain the interest of current scientific investigations. On the other hand, in…
