Uma nota sobre o triângulo de Pascal e a divisão por onze
Palavras-chave:Triângulo de Pascal, Divisibilidade, Palíndromos, Relação de Stifel, Teorema do binômio
Divisibility is an old topic that to this day intrigues and fascinates researchers and scholars. Several rules are well-known in particular the divisibility by eleven, since, for example, a palindrome with an even number of digits is divisible by eleven. In current times, divisibility has its applications, for example, in cryptography. Here, in this paper, we will show that applying two somewhat intuitive procedures to the lines of Pascal's triangle shall always yield numbers divisible by eleven. Illustrative examples are presented.
