 In base 10, a value is expressed by an n-tuple with n digits
 $$ D = d_{n-1}d_{n-2} \cdots d_1 d_0 $$
 This represents the value
-$$ V(D) = d_{n-1} * 10^{n-1} + d_{n - 2} * 10^{n-2} + \cdots + d_1 * 10^1 + d$$
+$$ V(D) = d_{n-1} * 10^{n-1} + d_{n - 2} * 10^{n-2} + \cdots + d_1 * 10^1 + d_0 * 10^0 $$
