@ -8,7 +8,7 @@ Say we have a sequence of nine digits, forming a partial ISBN-10: $n_1 n_2 ... n
The final digit, $n_{10}$, is calculated as follows:
$$
\Biggr( \sum_{i = 1}^{9} i \times n_i \Biggl) \text{ mod } 11
\Biggr( \sum_{i = 1}^{9} (11 - i) \times n_i \Biggl) \text{ mod } 11
$$
If $n_{10}$ is equal to 10, it is written as \texttt{X}.
